Sometimes, ATX isn’t big enough.

Perhaps you’re looking for a motherboard form factor that can accommodate the most high-end build/overclocking possible.

Whether it’s for the most powerful gaming PC, streaming rig, server, or even a production build, E-ATX is the way to go.

Which is why we’ve put together this feature on the best E-ATX motherboards available today.

(We’ve even included an XL-ATX choice for someone who wants the largest motherboard for their next monster setup).

Top Picks

Intel vs AMD EATX Motherboards

We’ve touched on this topic more in our motherboard CPU combos feature.

While AMD usually takes the top spot in the mid-range Micro ATX / ATX motherboard sizes, Intel is king for E-ATX.

There are simply more good options available between the Z490 and X299 chipsets in this form factor when building a very high-end PC.

This is why we’ve primarily focussed this guide on Intel options.

The picks below are some of the best options for Intel Core i9-9900K and 10th gen HEDT CPUs.

(But we’ve included a very worthy high-end AMD Extended-ATX motherboard pick for those interested).

Now, let’s get to it:

Overall Best E-ATX Motherboard: MSI X299 Pro

What a beast this is.

The X299 Pro strikes an amazing balance between accommodating different types of high-end builders whilst also maintaining excellent value for its price.

Let’s start with the graphics card potential for gaming/production builds.

With 4 x PCIe 3.0 x16 slots combined with an impressive bandwidth, you’ve got an SLI/Crossfire motherboard capable of 3-way graphics card integration.

On top of that, it’s filled with great onboard/BIOs facilities for overclocking

Combined with the right GPU/other hardware, this is an amazing 4k gaming motherboard.

It’s hard to imagine needing more for any upcoming games.

This is also a motherboard with 8 RAM Slots.

This means you can have up to 256GB of DDR4 RAM (overclocked up to 4200Mhz).

This memory capability will future-proof you for pretty much any build, even if you are video editing at 8K (and beyond) or building an intensive server PC.

The other great storage option that you’ll definitely want in a high-end build is 2 x PCIe Gen 3 x4 M.2 storage outputs.

Combined with the motherboard’s extended heatsink reaching over these inputs, you’ll have an amazing performance for dual NVMe SSD storage.

Easily one of the best LGA 2066 motherboards around, giving you compatibility with Intel’s Core-X processors, you’ll be able to achieve some incredible processing power.

The X299 Pro has many more great features that we could take all day describing, from a good featured I/O panel to great onboard audio.

While this is certainly one of the best gaming motherboards around, we would go further and say it has all you need if you’re building a high-end production PC too.

Simply put, if you’re looking at an EATX PC and don’t want to fork out double the price for the high-end picks below, this is a no brainer pick.

Runner-Up Best E-ATX Motherboard: Gigabyte X299X AORUS Master

If you have a slightly higher budget, this Gigabyte motherboard is an even more feature-packed option.

Boasting an X299X chipset, it’s a fantastic motherboard for Intel 10th gen CPUs (and 9th gen).

This board offers:

The above are just the highlights. 

There are a bunch of additional onboard/BIOs features that make this a premium motherboard (anything from excellent onboard heatsinks to great build quality for durability in a heavy EATX PC Case).

Combined they make this the best motherboard for overclocking at its respective price-point.

With the incredible graphics card, storage, RAM, and cooling capability, you’ve got an incredible motherboard for video editing, gaming, streaming, and production.

We wanted to give the Aorus master our top spot, but we think the MSI motherboard has everything the average E-ATX build will need for around 25% less cost.

That said, if your wallet is thick but not so thick that you’re looking at our high-end picks below, then this is likely the best mobo pick for you.

High-End Best Intel E-ATX Motherboard: MSI MEG Z490 GODLIKE

And now we come to the choice for those who care more for power than price.

Brand new to the market, this MSI motherboard is simply incredible.

To start, it’s built on the Z490 chipset / LGA 1200 socket, which combined with the features below, easily makes this one of (if not the) best motherboard for Core i9 10900K and other 10th gen CPUs.

  • 3 x PCI-e x16 slots
  • 4 x DDR4 RAM slots with max speeds up to 5000 MHz+
  • Fantastic I/O panel with Intel JHL7540 Thunderbolt 3 controller
  • 3 x M.2 storage outputs with Frozr heatsinks, and an adapter for a further 2

You may be asking yourself, “why does this board have less max RAM/GPU slots than our runner-up pick”?

Well, while we love the high RAM/GPU approach, the Z490 GODLIKE has chosen alternate bandwidth allocations.

Each motherboard can only circulate so much power and this MSI offering puts more into its CPU chipset, overclocking potential, and other features.

We’re sure you’ve also noticed that this is perhaps the best looking motherboard on the market.

With a fantastic array of headers for an RGB build, wonderful LED lighting, and an OLED screen to act as a “dashboard” for your computer status.

With a host of onboard features and incredible thermal solutions across the board, reviews are quickly finding that this is one of the best motherboards for overclocking available.

You’re going to get incredible high FPS 4K gaming if tied with the right CPU/GPUs, and a future-proofed production machine with the insane RAM overclocking.

If budget isn’t a concern, and your only question is “how do I achieve the most power” for your Intel build, this is the one.

High-End Best AMD E-ATX Motherboard: MSI MEG X570 GODLIKE

Now, we’ve focussed on Intel E-ATX mobos as there are better options for them in most of the price ranges.

But for a premium choice, MSI released an AMD version of our top Intel pick that is just as impressive.

This AMD offering stands out for a few reasons, but the biggest is that it’s one of the best X570 motherboards on the market perfect for Ryzen 9 CPUs.

The X570 chipset enables PCI-e 4.0 support which will give you incredible bandwidth/performance for top-end GPUs/M.2 storage.

While this bandwidth may not be fully exploited with all current hardware, you easily have one of the best motherboards for an RX 5700 / other 5000 GPUs as these can take advantage of it.

Let’s breakdown the spec highlights:

  • 4 x PCIe 4.0 x16 slots with 4-way Crossfire support
  • 4 x DDR4 slots with up to 128GB RAM OC’ed up to 5000Mhz+
  • 3 x onboard high-performance M.2 storage with an M.2 XPANDER-Z GEN 4 PCIe adapter allowing for 2 more, all with excellent thermal control
  • Incredible build quality, design and light features (including onboard lights, RGB header availability and OLED screen)
  • Fantastic onboard audio and Wi-Fi

As we’ve stated above, you can make an incredible gaming build with 2-3 GPUs.

But if you’re looking for more, this is perhaps the best Quad-GPU motherboard available today.

Additionally, the thermal solutions across the board will give you incredible overclocking capability, with benchmarks showing amazing OC performance on this board for RAM, CPUs, and GPUs.

The top of its class, the GODLIKE is one of, if not the best X570 motherboard on the market.

If your heart is set on AMD and this is out of your price range, there are good options in other form factors.

But if you have the budget, know that you really can’t get much better than this.

Best Budget E-ATX Motherboard: EVGA X299 FTW K

If you’re going for an E-ATX build, whether for high-end gaming or production, we’d recommend the picks above.

That being said, what EVGA manages to fit into this cheap EATX motherboard is insane for the price.

This includes:

  • 8 x DDR4 RAM slots for up to 256GB memory
  • 4 x PCIe x16 slots with capability for up to 3-way SLI GPU builds.
  • 2 x M.2 storage outputs
  • Great onboard lighting (though not as many RGB header options available as the above/others)

As you can see, you still have the utility here for a high-end build for gaming, streaming, video editing, and other production rigs.

You don’t have the same level of onboard features for overclocking/cooling as you do on the above boards, but it’s still capable of great clock speeds across your hardware.

Aside from that, the biggest problem here is the user complaints of issues.

It’s common for hardware that seems “too good to be true” for its price point to have lots of users complaining about defected units.

Now EVGA is a big manufacturer and you can expect your warranty to cover problems.

But depending on what the issue/s are, it may be painful to go through the process as it appears to have been for many others.

That being said, such a risk is a worthy trade-off if you can’t afford the other mobos and want an E-ATX PC.

One of the cheapest X299 motherboards available, if you’re trying to build a high-end machine on a budget, this is an incredible pick.

Best XL-ATX Motherboard: Gigabyte X299X AORUS Designare 10G

We’ll start by repeating what is said in our complete guide to motherboard sizes:

You don’t need an XL-ATX motherboard over an E-ATX one for a large high-end build.

The options above will give you more than enough for a premium gaming motherboard (or for production, streaming, etc).

That being said…

If you simply want more space to play with in a “super tower” PC case, we included this as it’s still a fantastic pick.

A Socket 2066 motherboard, the AORUS Designare boast:

  • 8 x DDR4 RAM slots for up to 256GB memory at 
  • 4 PCIe x16 outputs capable of 4-way CrossFire or SLI builds
  • A fantastic I/O panel including 2 x Thunderbolt 3 connectors
  • Great Onboard Realtek ALC1220-VB HD audio
  • Gorgeous LED lighting with great RGB header support for an RGB build
  • Fantastic build quality with lots of port reinforcement, good for such a large setup

When you can combine this colossal graphics card capability with all of the onboard thermal solutions/excellent BIOs, you have one of the best gaming motherboards for overclocking.

Its price-point sits in between our top picks and high-end picks, and we’d say that’s about right for what it offers.

If you’re looking to build an absolute monstrous PC both in power and size, this is perhaps the best XL-ATX Intel motherboard available.

Deciding what order to buy your gaming PC parts in is hard.

One of the worst offenders is choosing which CPU & motherboard you should pair.

With countless variations, the whole process is unnecessarily confusing.

Which is why we’ve collated the best CPU motherboard combinations available for all different sizes, purposes & budgets.

This is a long feature – we recommend scrolling to the headings you’re actually interested in instead of reading it top-to-bottom.

 Table of Contents

AMD vs Intel CPUs/Motherboards

No feature on this topic would be complete without a say on the “is AMD better than Intel?” battle.

We’ll keep it short as there’s already a lot of good info on this topic.

For this generation of CPUs, both flagship models from each manufacturer give great performance for gaming and other build purposes.

But if looking at the numerous benchmarks available for games/production for both brands with price in mind: AMD tends to have an edge.

Many of the current-gen Intel CPUs are fantastic.

But on average, you’re usually paying a little more for the performance you can get from the AMD alternative.

A lot of credit is given to Intel for its integrated graphics processors on many of their CPUs.

But really, we find this a borderline moot point.

Anybody seriously building for gaming/production/streaming is going to want a standalone graphics card.

For motherboards, the AMD versions tend to be cheaper also (with the exception of Mini-ITX).

Short answer: We’d push you towards an AMD build to get the highest value CPU motherboard combos.

But we do understand some people are just more comfortable with Intel.

Don’t fret – know that the Intel motherboard combos we’ve recommended below are still great for their respective price-points.

With that said, let’s get into it:

Overall Best AMD Motherboard CPU Combo:

AMD Ryzen 7 3700X with ASUS ROG Strix B450-F

To start off our list, we’ve chosen what we think is the best gaming CPU motherboard combo available for an “all-round”/mid-range build.

The AMD Ryzen 7 3700X is a fantastic accomplishment in CPU engineering.

Offering 8 threads and 16 cores with a max frequency of 4.4GHZ, this AMD processor packs an incredible punch for its competitive price.

Its utility will hit the sweet spot for what most gamers need.

You have a great basis here for a powerful gaming build that will accompany some intensive GPUs (including multi-crossfire builds).

Tied with some decent VGA hardware, this CPU is more than capable of running a 1440p/4k gaming PC.

The included stock cooler also performs decently and looks great with its color-controllable LED lighting.

Outside of games, the 3700x is very capable of general multi-purpose PC tasks (benchmarking well in tasks across the board, not just gaming fps tests).

Meaning it’s a great CPU for streaming, video editing, production, and more.

If this is the budget you have for a processor, we really can’t recommend it more.

The ASUS ROG Strix B450-F is a popular motherboard for a reason.

With its ATX form factor and B450 chipset, the ASUS mobo has pretty much everything we expect a majority of gamers to need.

You’ve got:

  • 3 PCI-e slots for a multi-GPU build (or integrated sound/network cards as required)
  • 4 x DDR4 RAM slots
  • Dual NVMe M.2 storage options
  • Great onboard sound
  • Gorgeous RGB lighting and 2 headers for a great RGB build.
  • Stylish and well-equipped I/O panel

It’s a great motherboard for overclocking, with lots of good onboard features as well as a great, user-friendly BIOs.

For the price, we really think the Strix B450-F hits the sweet spot between offering features without reaching “diminishing returns”.

If we had to choose one CPU/motherboard combo to recommend for the majority of gamer computers (and other production needs), this is it.

Overall Best Intel Motherboard CPU Combo:

Intel Core i7-9700K with MSI Z390-A PRO

Our top Intel picks are also a great hardware pairing.

They perform a tad better but cost a fair chunk more as we discuss below.

The i7-9700K is, with performance-per-$ in mind, the best Intel CPU for gaming today.

The processor packs 8 cores/threads and the very impressive capability to overclock up to 4.9Ghz.

It performs excellently across gaming tests and tied with a good GPU (or 3), will grant you excellent performance for games and other tasks.

Certainly more than capable of being the basis of a powerful 1440p/4k gaming build.

i7-9700K vs Ryzen 7 3700X

These frontline CPUs have faced off in loads of benchmarking tests.

The short answer?

They come out very close.

The i7-9700K performs slightly better in most gaming FPS tests, but not enough to be decisive.

The Ryzen 3700X tends to perform marginally better at other computational tasks (anything from unzipping files, to compression, to multi-tasking).

Because of this, we would certainly recommend the R3700X if you’re interested in also building a PC for streaming, video editing, and/or production work.

Now, you may think that makes the Intel CPU the best choice for gaming.

We’d agree if you happen to see them at the same price.

But nearly always, the 3700X (and accompanying motherboard) work out significantly cheaper.

That saved budget would be much better spent on buying a more expensive GPU, the AMD CPU will still be able to work with a very intensive VGA demand.

The MSI Z390-A PRO is one of the best value Intel motherboards on the market.

An ATX form factor mobo, it has excellent overclocking facilities (with some nice bells and whistles like an extended onboard heatsink).

The main features include:

  • 2 x PCI-e ports (1 with reinforcement to reduce GPU sag, though don’t read into this as a huge deal)
  • 4 x DDR4 / DIMM slots
  • NVMe support
  • Good onboard sound
  • I/O panel that includes USB 3.1 type C output

You’ll note it has 1 less PCI-e port than our top AMD offering.

While this would be a nice addition, we doubt many of you looking at a mid-range build will require more than 2 (if you do and want to stick to Intel, check out our high-end pick below).

It has everything you’d expect in a decent mid-range Z390 motherboard and works great alongside the 9700K.

Best Budget AMD Motherboard CPU Combo:

AMD Ryzen 5 3600 With ASUS TUF B450M-Plus Gaming

As far as cheap AMD CPUs/motherboards go, the below pair is the best value combo for gaming.

You can go cheaper, but these next AMD/Intel combos are the lowest we’d recommend for most gamer needs.

If however you just want a PC for general use/light gaming, see our “cheapest” picks further below.

The Ryzen 5 3600, as far as cheap gaming processors go, is our favorite.

Providing great performance for a 1080p/1440p gaming build, you’re still able to run some decent graphics hardware alongside this CPU.

Offering an impressive 6 cores, 12 threads, and max 4.2 GHz, it’s got an impressive spec for a budget processor.

The included Wraith Stealth cooler is not the best on the market but will get the job done for a budget gaming build if you don’t want to buy standalone.

You still have enough power in this processor to stream and perform other intensive tasks (respecting that they, of course, won’t be quite as fast as the more expensive builds).

Overall what you get for the price in this CPU is fantastic.

If it’s as far as your budget can stretch, you’re still going to be able to create a great PC for gaming.

The Asus TUF B450M-Plus Gaming is a great cheap AMD motherboard option that still offers everything you need for most games.

It’s a Micro ATX form factor, which is more cost-effective than their ATX counterparts (including cheaper cases).

The board includes:

On top of it still having reasonable overclocking capability, features like NVMe M.2 / RGB inclusions are really impressive for the low price point.

You’ll likely just be buying 1 GPU for a budget gaming build, but it’s nice to have the option to expand with the second PCI-e slot later on.

Overall, this cheap CPU motherboard combo still has everything you need to play the latest games at reasonable settings.

Best Budget Intel Motherboard CPU Combo:

Intel Core i5-9400F With Asus Prime Z370-P II

Our budget Intel combo is also worth your consideration, especially if they happen to be cheaper/on a deal whenever you’re browsing.

Note: it seems that manufacturers are fading out the Z370 chipset motherboards. 

We’ve included the best value one below but if made unavailable, your best bet will be to tie the i5-9400F with our best overall motherboard: The MSI Z390-A PRO

If you’re looking for a cheap Intel gaming CPU, The Core i5-9400F is the best option.

We’re specifically recommending the non-graphics integrated version because even in a budget gaming build, you want a standalone card.

With a clock speed of up to 4.1GHZ and 6 cores/threads, this Intel offering still packs a punch and can be paired with a decent GPU.

i5-9400F vs Ryzen 5 3600

At the time of writing this, the two budget CPU options are around the same price.

Originally the Ryzen 5 3600 was a more “premium” option, and it shows in the benchmarks.

The card tends to perform 10-20% better across the board, from games to general PC tasks.

If the Intel option happens to be significantly lower price at the time you’re looking, then, by all means, go for it.

But if the prices are what we expect, then the 3600 is the best value CPU for gaming available.

But the 9400-F will still get a lot done in a production/gaming/streaming build should you want to stick to Intel.

The Asus Prime Z370-P II is the best cheap gaming Intel motherboard available on the market today.

It may soon be discontinued as manufacturers move towards focussing on the Z390 chipset.

If you can’t get this motherboard, go for the MSI Z390-A PRO.

This ASUS offering is an ATX motherboard. It’s great that it retains the good value at this form factor, offering:

  • 2 x PCI-e slots
  • 4 x DIMM/DDR4 RAM slots
  • Dual NVMe M.2 Storage option

It won’t have as many bells and whistles as our mid-range picks (RGB headers, reduced overclocking facilities, no USB 3.1 type C, etc).

But as far as the utility you need from a budget gaming build?  This Asus motherboard has everything you need.

Cheapest AMD Motherboard CPU Combo:

AMD Ryzen 3 3200G With Asus Prime B450M-A

Let’s be clear:

If you’re serious about building a gaming PC, or one capable of decent production/streaming output, then the budget picks above should be the minimum.

That being said…

What if you’re happy with a PC that’s just for lightweight gaming (e.g. Fortnite on fairly low settings/older games) and general web browsing/Netflix etc?

We’ve included the cheapest CPU motherboard combos we’d recommend if this fits what you’re after.

For its low price point, the AMD Ryzen 3 3200G manages to pack an impressive amount and is the cheapest AMD CPU for gaming we’d recommend.

Still packing 4 cores/threads, max frequency of 4.0GHZ, and an included wraith stealth cooler (enough for a cheap setup).

With your budget in mind, AMD has included integrated graphics into this CPU.

But know for games, the performance will be pretty poor, you’d be playing games on low at best.

Therefore even if your budget is tight, try to stretch to a standalone card.

That being said, don’t be put off if you can’t afford some of the better picks on this list.

You can still play plenty of great modern games with this AM4 CPU when combined with a fair GPU (just not at crazy settings/resolutions!).

The Asus Prime B450M-A is definitely the cheapest AM4 motherboard we’d recommend.

At its Micro ATX form factor, you’re getting:

  • 1 x PCI-e slot
  • 4 x DDR4 compatible outputs
  • Surprisingly, an RGB header should you ever need
  • An NVMe M.2 storage option

As far as overclocking goes, you’ll be limited on this board.

But in a budget build, you’ll not want to spend lots on cooling anyway.

Put simply: this mobo and CPU combo is excellent for someone looking at the minimum for supporting a gaming PC.

Cheapest Intel Motherboard CPU Combo:

Intel Core i3-9100F With MSI H310M PRO-M2 Plus

When considering i3-9100F vs Ryzen 3 3200G, the performance in this category is actually quite comparable.

So if you’re looking for the cheapest Intel CPU motherboard combo, rest assured that this option is as good as AMD’s offering.

With that said, if you don’t have a brand allegiance, we’d recommend you just pick whichever of the two pairs happens to be cheaper at the time you’re looking.

The Intel Core i3-9100F is as cheap as you can get for an Intel gaming CPU.

With similar specs to the AMD offering, you’re looking at 4 cores/threads and clocks up to 4.2GHZ.

A basic cooler is included (all you’d want for a very low budget PC).

Integrated graphics are not included, but as always, you want to fork out for a standalone card if you’re interested in gaming anyway.

One of the cheapest Coffee Lake CPUs available, this offering isn’t really designed for gaming as you can expect from the price.

But if you’re happy with lower settings on less demanding games (or just want a PC for general purposes) this can still manage your needs just fine.

The MSI H310M PRO-M2 Plus, to put it simply, is the cheapest Coffee Lake motherboard that won’t bottleneck a basic gaming build.

Another mATX mobo (as expected for the budget), you have:

  • 1 x PCI-e slot
  • 2 x DDR4 compatible outputs
  • NVMe M.2 support
  • Acceptable onboard sound

Of course, at this very cheap price point, you’re not getting much more than the minimum.

But really in a budget build, you only need 1 PCI-e slot and 2 x RAM slots anyway.

Coming in at an exceptionally low price-point, this Intel CPU motherboard combo is perfect for anyone who really needs to make every $ count.

Best High-End AMD Motherboard CPU combo:

AMD Ryzen 9 3900X With Asus Prime X570-Pro

If price is not a concern, the next pair is the best CPU motherboard combination on the list.

Of course, at these prices, this is for a very powerful gaming build or someone after a high-end production/video editing/streaming PC.

For the average gaming PC, you’ll do well with the top picks above.

But if you’re more interested in power than budget, keep reading!

The AMD Ryzen 9 3900X is an incredible piece of hardware.

With a monstrous 12 cores, 24 threads, and overclockable up to 4.6GHZ, despite its high price-point, it still somehow manages to feel impressively valuable with all this included.

The processor will be more than capable of running a high-intensity multi-GPU build.

As far as gaming goes, provided you have the high-end VGAs to match, you can consider yourself future-proofed, 

This Ryzen 9 CPU will be capable of working alongside top-end graphics cards to act as a 4k gaming PC (with decent settings/fps to boot).

This AMD offering also performs excellently across benchmarks for pretty much all other major computational task tests.

Meaning its a perfect CPU for production, video editing, and the best streaming processors for absolute top quality/multi-tasking.

The processor also comes with a good quality LED cooler, good for the basis of an RGB build.

This cooler won’t compete with standalone heatsinks or CPU water coolers (that we expect most high-end builders to go for) but it’s a nice inclusion nonetheless.

It’s hard not to rave about the 3900X and its superb feature set, it’s one of the best CPUs for overclocking and if you’re looking for a top-quality gaming build, start here.

Ryzen 9 3900X vs 3950X

Some of you may be wondering why we chose the 3900x over its more powerful brother for our top-end pick.

With an additional 8 threads and higher overclocking potential, the 3950X is indisputably better.

But for around 50% extra cost, there are pretty huge diminishing returns.

If you also need your build to be state of the art for production purposes or want to ensure you can max out games like RDR 2 and Cyberpunk 2077 (when it comes out) at a very high resolution/FPS, then definitely go for the 3950X.

But otherwise, even for your high-demand gaming needs, we think the 3900X will match what you need (spend the delta on better GPUs).

The Asus Prime X570-Pro Ryzen 3 is one of the best AM4 motherboards available today.

With the X570 chipset, you’ll have access to not only the best processor power draw around today (to max out that expensive CPU), but also PCI-e 4.0.

The main utility here is for GPUs and NVMe storage performing at faster speeds.

This is great for top-end builds, and while you may not see the full capability of PCI-e 4.0 for another few years, it means you’re investing in a future-proof motherboard.

In terms of other features, oh boy, the list is plentiful and we won’t cover it all in the summary, but for the highlights:

  • ATX form factor with 3 x PCI-e slots
  • 4 x DDR4 slots
  • Dual NVMe M.2 support
  • Fantastic onboard sound (Realtek 8.1 S1220A)
  • Beautiful onboard RGB lighting, 2 addressable headers, and 1 standard RGB header, perfect for an RGB build.
  • Numerous other onboard BIOs features for overclocking & optimization

Yes, the board is expensive.

But for enthusiasts, the quality of life features you get for overclocking amongst all the points mentioned above really make it a gem.

You can go a lot more expensive with motherboards, but we’d say this is the sweet spot even for the most avid of power builders.

If we had to pick just one: this is the best gaming motherboard CPU combo we’d recommend in the entire list.

Best High-End Intel Motherboard CPU combo:

Intel Core i9-9900K With MSI MEG Z390 ACE

Our most expensive Intel CPU motherboard combo is a worthy competitor to AMD’s offering.

The Intel Core i9-9900K is one of the most popular CPUs of the current generation, and for good reasons!

With 8 cores, 16 threads, and up to 5.0GHZ clock speed, you can get amazing speeds out of this processor for a gaming computer.

As far as other tasks go, the CPU always perform excellently, benchmarking very well for the needs of a production or streaming PC

i9-9900K vs Ryzen 9 3900X

A battle of titans.

Both of these are amazing CPUs for gaming.

With that said, in all the benchmarking done for these 2, there is a slight edge to 3900X.

That is across lots of different factors, from gaming to various general PC task tests.

It isn’t completely unanimous, with the i9 recording some slightly better fps peaks in some 1080p tests.

But it’s clear that the Ryzen CPU tends to take the victory if we had to choose.

We also like that the AMD CPU comes with PCI-e express support, which future-proofs your next gaming setup when combined with our recommended motherboard.

If however, when you were browsing, the i9 CPU motherboard combo was >10% cheaper, it would likely be worth the savings as they are still close in performance.

One final thing to bear in mind: the 3900X includes a nice LED RGB cooler and the 9900K doesn’t include even a basic stock cooler.

Though we expect most of you will be going for a standalone option anyway.

Intel i9 9900K vs Intel 10900x
If you keep up with PC news, you’ll know the 10900x is the “new guy” in town.

The CPU is currently very hard to get hold of and quite pricey.

Although the architecture behind it is very impressive (as you’d expect from the next-gen comet lake CPUs), in real-world performance terms, it’s a tad underwhelming.

Benchmarks vs existing CPUs show only marginal improvements.

Even for enthusiast builds, we would stick with the 9900 or comparable AMD offerings for the time being.

The MSI MEG Z390 ACE is one of the best Z390 motherboards around if your wallet is thick.

Let’s start with the design.

We don’t often focus on style for motherboards…

But tied with a nice visible PC case, the Z390 AC will look fantastic with its slick RGB lighting and steel fixtures (on PCI-e slots, etc).

It’s an ATX motherboard which like our top AM4 motherboard, has too many features to list.


  • 3 x PCI-e slots
  • 4 x DDR4 slots
  • 3 x M.2 support (with 1 x integrated M.2 heatsink)
  • Very good integrated sound (Realtek 8.1 S1220A)
  • Excellent rear I/O panel including a USB type C port.
  • Also (rather uncommonly) includes potential inputs for 2 x USB type C ports for the front I/ O panel
  • Beautiful onboard RGB lighting and addressable headers for an RGB build.
  • Locks of overclocking utility within the BIOs/onboard heatsinks

If you’re looking for an Intel gaming motherboard CPU combo in the era of Coffee Lake/Z390 and you have the money, this is the pair you want.

Best Micro ATX AMD Motherboard CPU Combo:

AMD Ryzen 7 3700X With ASUS Prime B450M-A

For those of you looking for a Micro ATX AMD Gaming PC we’ve combined our best gaming CPU pick from the top of this list with a great, affordable mATX motherboard.

We’ve already been over the AMD Ryzen 7 3700X at the top of our list (where it belongs).

It has returned because it’s easily the best Ryzen CPU for gaming when considering a “mid-range” user.

The 3700X is a great choice for an mATX CPU Motherboard combo too because you’re still going to be looking for good processor power in a mini-tower gaming PC.

With its 8 cores / 16 threads, it will be very effective for single/dual GPU setup (2 is the most you’ll do with a Micro ATX mobo).

What else is there to say that we haven’t already?

This is the best value gaming CPU on the market today. If it fits into your budget, pick it up.

The Asus Prime B450M-A has an impressively dense feature-set for its mATX form factor and low price.

You’ll be getting:

  • 1 x PCI-e slots
  • 4 x DDR4 RAM slots
  • NVMe support

And solid onboard features/BIOs to enable customization/good performance.

We’ve recommended a board with 1 x PCI-e slots as imagine many of you looking at building a Micro ATX gamer computer will be focussing on single-GPU builds.

If you want a crossfire gaming PC (or the potential for one later), you can fork out more on the Gigabyte B450M DS3H (still compatible with the Ryzen 3700X).

You’ll note that there are some cheaper 2 x PCI-e AMD mobos floating around.

But some other features you lose out on (limited SATA availability/other power draw concerns around the board) are not worth it unless you’re sticking to a very cheap build.

Overall, this motherboard, combined with the most popular AMD gaming CPU on the market will make your setup a powerhouse when combined with a good GFX card.

Best Micro ATX Intel Motherboard CPU Combo:

Intel Core i7-9700K With ASRock Z390M PRO4

For the Micro ATX Intel CPU motherboard combo, we’ve also returned to our top CPU pick tied with an excellent value mobo.

The Intel Core i7-9700K is just as good a CPU for an mATX gaming PC as it is for our top (ATX) based combo.

The only extra thing to bear in mind for a smaller build is with the lack of stock cooler, you’ll be putting effort into buying a CPU cooler that’s compatible with a mini-tower case.

There’s usually enough room in this form factor for a majority of them though (just ensure you check dimensions).

The 9700K is more than capable of running greatly alongside a powerful GPU (or two), which is what you’d be looking at in an mATX PC.

What more is there to say?

This is the best Intel CPU for gaming today with the average budget in mind, and great for an mATX computer.

The ASRock Z390M PRO4 is such an impressive value-offering, for most mATX CPU motherboard combos, this is more than good enough.

You may not have heard of ASRock to the same extent as say, ASUS or MSI.

But rest assured they are an excellent motherboard manufacturer, especially in the affordable price ranges.

With this board, you’re getting:

  • 2 x PCI-e slots
  • 4 x DIMM outputs
  • Decent onboard sound

It’s a motherboard for a dual-GPU build should you need it in the future (unlike the AMD mATX ASRock board on Amazon, it doesn’t sacrifice as much on SATA/power draw to have that extra slot).

If you have the budget for a mobo with some more bells and whistles (better M.2/RGB capacity, slightly improved audio & integrated wi-fi) then you could also go with the excellent MSI MPG Z390M.

But the ASRock will give you everything you need for a “no-frills” base and is a perfect pair with the Ryzen for an mATX CPU motherboard combo.

Best Mini ITX AMD Motherboard CPU Combo:

AMD Ryzen 5 3600 With B450I GAMING PLUS AC

For the smallest form factor, we’ve chosen a pair of slightly more affordable options given you don’t need a CPU that powers a huge powerhouse in an mITX gaming PC.

We’ll discuss potential upgrades should you have the budget though.

The AMD Ryzen 5 3600 is another offering we’ve already raved about in our budget pick.

Easily the best Ryzen 5 CPU for gaming, the cores/threads you’re getting for the price is fantastic.

Why are we going for a “budget CPU” for the top Mini-ITX combination?

Well, in mITX builds and PC case sizes for the form factor, you’re going to be sticking to single GPU builds.

With this in mind, the 3600 is a good enough CPU to not bottleneck one graphics card for your gaming.

Don’t get us wrong, you’re still going to get some decent extra juice out of our favorite pick, the Ryzen 7 3700X, if you have the budget.

Especially if you want a mini-ITX streaming PC or a CPU for video editing/production.

But overall, we think this Ryzen 5 processor will cover what most of you will need.

So don’t fret if it’s the furthest your budget can stretch for your mITX gaming computer.

The MSI B450I GAMING PLUS AC is pricey, but also the best Mini ITX AM4 motherboard on the market.

Decent mITX AMD motherboards seem to be more expensive than the Intel category.

A tad unusual in this generation. We expect this is simply because of supply/demand.

That being said, if you’re looking at a mITX build, this is still a great option, with:

  • 1 x steel-plated PCI-e slot (standard for the form factor)
  • 2 x DDR4 RAM slots (also standard for mITX)
  • Decent onboard sound
  • Included wi-fi (recommended for mITX so you’re not relying on limited USB/PCI slots)
  • A well-featured I/O panel, considering the size

Combined with either the Ryzen 5 or Ryzen 7 CPUs above, you have a fantastic basis here for a gaming PC.

Remember with a ITX computer/ single GPU, you’re not going to get quite the same power as you would out of something larger.

But know that if that single GPU is a powerful one, you can still create a great portable gaming PC/something suitable for LAN parties or a VR demo build.

This small CPU motherboard combo will also still perform great with other general computational tasks too if you have video editing/streaming in mind.

Best Mini ITX Intel Motherboard CPU Combo:

Intel Core i5-9600K With ASRock Z390M-ITX/ac

When it came to confirming the best CPU motherboard combos for mITX, we actually found that Intel came out looking better than AMD.

Not something we saw in many of the other categories, so take this pair seriously!

Last but certainly not least on our list is the fantastic Intel Core i5-9600K CPU.

The smaller brother of the i7-9700K, the CPU still manages a decent 6 cores/threads and up to 4.6GHZ clock speed.

The base clock speed is also 3.7GHZ, which is nice for those worried about overclocking in such a tight form factor where cooling is often minimal.

Combined with the below Mini-ITX Z390 motherboard, you have a great combo here to tie with a single GPU for a powerful gaming build.

i5-9600K vs i7-9700K

Some users may wonder if it’s worth forking out more for the i7 CPU, which we consider the best Coffee Lake CPU for gaming with price in mind.

Well, while it’s great for ATX/mATX builds, it’s probably a tad overkill for ITX PCs.

If you’re looking to build the best mITX gaming computer you can, by all means go for the 9700K.

It will also open up more capability in the way of multi-tasking/other task speeds – whether that’s for a streaming setup, video editing, or a production rig.

But we expect most people looking at mITX are more interested in achieving a decent, but not “ultra-powerful” portable PC.

For you guys, be comfortable knowing the 9600K is enough alongside a great GPU.

i5-9600K vs Ryzen 5 3600 combo

When putting our smallest CPU motherboard combos head-to-head, we think in this case, Intel comes out on top.

When it comes to the CPU specifically, the 9600K performs slightly better in gaming.

The Ryzen 5 3600, with its increased threads, will be marginally better at multi-tasking.

But really, they’re in the same ballpark. 

The Ryzen 5 3600 is usually more valuable as it’s typically around 10-15% cheaper.

The reason we choose Intel here?

Because the mITX Intel motherboard options are better than AMD’s.

The value you’re getting from the cheaper motherboard outweighs what you get from the cheaper processor.

By all means, if you check the prices of our top picks on Amazon via the links and see the AMD combo at a lower price, go for it.

But chances are, the Intel offering is cheaper, and we think, your best choice for this form factor.

The ASRock Z390M-ITX/ac is what makes this pairing so valuable and in our view, the best Mini ITX CPU motherboard pairing for either Intel or AMD.

At a very impressive price-point, you’re getting.

  • 1 x PCI-e slot (the mITX standard)
  • 2 x DIMM slots (also the mITX standard and still gives you up to 32GB RAM)
  • Good quality onboard audio
  • Integrated Wi-FI
  • NVMe support

Again remembering that on a miTX motherboard you’re obviously limited compared to larger form factors, this is a fantastic value offering.

Having NVMe support is really nice for a tiny build where storage space matters.

Integrated Wi-Fi at the price point is very useful when you have limited USB/PCI slots too.

Simply put, if you add a decent graphics card, this Intel CPU motherboard combo will be fantastic for an mITX gaming computer.

Final Word

We appreciate how long this feature is and how much information you have just digested!

If you’re feeling overwhelmed, know that we only provided so many options to ensure every size, budget & requirement.

If you want the short answer for what suits most PCs for gaming, streaming, production, and general usage: go with our top AMD choice.

We put this combination at the top for the reason and really stands out as being perfect for most users.

But rest assured, whatever category you’re most focussed on, know that these options are all fantastic for their respective price-points and great basis’ for your next exciting build!

Motherboard Sizes Explained

E-ATX Motherboard

The largest of the main types. An Extended-ATX motherboard is for builders focussed on building the most powerful PC possible.

This mobo form factor is designed to work alongside a full tower PC case, providing you with incredible space/features.

This often includes support for Quad-GPU builds and 8 RAM slots (which could achieve up to 256GB of memory).

Not to mention the breathing room to cool all of these components with immense overclocking potential.

Perfect for very high-end gaming & production (editing, rendering, etc), an E-ATX motherboard will open up utility you can’t get from any other size.

Note that there are, of course, diminishing returns when building such a powerhouse.

If you’re the average gamer or don’t need the best PC money can buy, E-ATX can be overkill.

The boards are very expensive and alongside an E-ATX case, are enormous. Make sure you have space.

That being said, if you care less about the budget and more about the most power possible, this is the size for you.

ATX Motherboard

The mid-tower motherboard. ATX has reigned as the most popular size for a long time, and for good reasons.

When considering EATX vs ATX, sure the latter will have slightly less space for high-end builds.

But ATX still has everything important to the majority of gamers/enthusiast builds.

Including support for 2-3 GPUs, 4 x DDR4 RAM, plenty of SATA ports, and their ATX case-counterparts come with plenty of decent cooling options.

Even if it’s not the best motherboard for overclocking (that belongs to E-ATX), it’s still a very close second and will achieve what most gamers need.

The other great advantage is due to the popularity, there are so many good ATX mobos available at competitive prices.

An ATX build is still going to be fairly big with limited portability. Bear that in mind if you’re building an on-desk setup.

But overall, if you’re looking for the best “all-round” option, an ATX build is the way to go.

Motherboard Sizes 2

mATX Motherboard

While ATX may be the most popular overall, Micro ATX motherboards have been giving them a run for their money in the last few years.

Why? Well, the quality of this form factor has dramatically improved.

With a majority now having 4 x DDR4 RAM slots, good SATA connector availability, and even 2 PCIe slots for a small SLI/Crossfire GPU build.

This is the smallest PC build you can create while still accomodating a majority of mainstream components.

Note that as we get to this size, running a dual-GPU build will usually get cramped and isn’t ideal.

It’s certainly possible, but the preference would be to stick to a single graphics card (with the utility to overclock).

As we discuss further below in our top picks, the Micro ATX motherboard size nails affordability.

If you want something compact/cheap but not so small that you have to be extra careful with your hardware choices, this is the pick.

mITX Motherboard

And then there are those looking for the smallest PC possible.

A Mini-ITX build is for those very focussed on portability or a compact style (e.g. LAN-party build, HTPC, or perhaps a streaming computer).

With such a tiny size, you’re of course compromising on feature availability.

Most Mini-ITX mobos come with 2 RAM slots (still providing up to 64GB), a single PCIe slot, and limited SATA ports.

The cases that support them are also on the smaller side. Leading to limited ventilation/cooling. You’re going to struggle with overclocking.

With this small size, you will need to pay more attention to the other parts you buy (most notably GPU/PSUs).

This can often include having to buy parts that are a bit more expensive (usually offset by the cheap motherboard and cases, however).

With all that being said, the convenience of a portable PC is massive and compact builds often look fantastic.

If this is what your heart is set on, don’t fret! You can build a great gaming computer on a Mini-ITX motherboard.


How to Choose a Motherboard Size

Ahead of giving you our top picks, we’ve broken down the key criteria for what to look for in a motherboard.

Just know that not all these factors will be important to you individually (many people don’t need to worry about having more than a few SATA ports, etc.).

Don’t be overwhelmed by all the factors, just focus on what’s important to you, and check out our recommendations if in doubt.

Computer Case Size Comparison Chart

Form Factor / PC Case Size

Let’s start with an obvious one.

Whatever motherboard you pick, you want to make sure that you have an appropriately sized case to go with it (e.g. E-ATX case for an E-ATX motherboard).

Check out our joint-feature on PC case sizes if you want more info.

But in short, the type of motherboard you want will probably also guide the case size you need anyway (e.g. if you’re looking at a smaller motherboard, the case will have fewer hardware space/cooling options, but that’s the trade-off for portability).

CPU compatibility

Motherboard CPU CompatibilityAlthough not explicitly related to size, this one is worth covering as it’s one of the most important buying factors.

When purchasing a motherboard, make sure it’s compatible with the CPU you’re looking at.

Firstly there’s LGA vs PGA vs BGA.

There’s already good resource if you want the very technical explanation, but in short:

  • LGA is most common for Intel CPUs.
  • PGA is most common for AMD CPUs.
  • BGA is more for manufacturers and not worth considering for your individual build.

Note: this isn’t universal, you may (rarely) in the future see an AMD CPU on LGA – but this will usually be very clear in a listing.

The most common socket types right now are LGA 1151 for Intel, and AM4 for AMD.

These will support the most common CPUs you’ll be looking at for gaming.

There will be more terms in this area that will probably confuse you like Z370 vs z390 (which is mainly just a difference in wifi/USB compatibility).

If you are confused here, don’t worry – just check the product listing!

We’ve only provided this info for the full picture. Once you’ve found the CPU you want, it’s pretty clear what a motherboard supports in the product listing like below:

CPU Chipset Compatibility Explained


PCI Slots

Motherboard PCIe SlotsOne of the big factors for a gaming computer.

The larger your motherboard size, the more PCI Express (PCIe) slots you will have available, these are what allow you to install graphics cards.

An E-ATX motherboard for example, will often have 4 PCI-e 3.0 slots, allowing for a 4-way GPU PC. 

Aside from GPUs, other PCI slots are often included if you have other focusses (e.g. installing a high-quality independent sound/network card).

Just know that you’ll usually have to put them in a place that blocks you from fitting an extra GPU.

That’s the beauty of a large motherboard though. Not many people need 4 GPUs, so those PCIe slots can come in handy for other things.

PCI-E x4 vs x8 vs x16

When looking at PCI-E slots you may notice the different numbers next to them (i.e. PCI-E 3.0 x4/x8/x16).

Putting it simply, a motherboard can only circulate a certain amount of data/bandwidth at a time.

So if you have a lot of PCI-e slots, some of them will be x4 – x8 which means they can’t output the same bandwidth as your main x16 slot/s.

But: There have been many benchmarks on what the performance difference is between these types.

The difference between PCIe x4, x8, and x16 is very minimal for performance/gaming.

We’re talking a couple of FPS in games.

This is because most GPUs don’t come close to actually requiring the x16 power that an x16 slot provides.

Whichever x type, you’re still going to be getting a majority of the card’s power overall.

SATA Ports

Motherboard SATA portsLarger boards will come with more SATA ports to allow you to connect more SSDs, HDDs and optical drives.

For most gaming builds, you’ll have more than enough SATA ports for your requirements on most boards.

It’s worth checking if you’re purchasing an mATX / mITX motherboard to ensure you have enough.

It’s only if you’re building say, a video editing PC, or if you have other requirements that means you want to install a lot of storage, should you be too worried about confirming these beforehand.


NVMe M.2 Storage

Motherboard M2 StorageM.2 storage is less common than the standard 2.5″ SSD but worth your consideration if you’re all about speed.

It’s a type of solid-state drive that larger motherboards have become more compatible with over the last few years.

M.2 SSD vs SSD (2.5″) – An M.2 SSD installed via NVMe is around 5 times faster than a SATA-installed SSD.

Note that this is during benchmarking. In real terms to the user, this will likely be around 2-3 times faster.

These storage units are of course a lot more expensive (here’s our top pick) but run like a dream when you’re installing your OS and common apps on there.

If you like the sound of this, we recommend looking at an ATX or E-ATX motherboard.

You might be able to squeeze out the utility for an NVMe M.2 within mATX but it will likely mean the board is sacrificing bandwidth somewhere else.

Most motherboard listings will detail their support for this storage type so don’t fret about compatibility too much.

Just make sure to get an NVMe M.2 SSD (SATA ones perform similarly to a 2.5″ SSD) – here’s our top pick.

RAM slots

Motherboard RAM SlotsA majority of motherboards from E-ATX to Micro ATX will provide a minimum of 4 x DDR4 RAM slots.

The smallest form factor, mITX, tends to come with a maximum of 2 x DDR4 RAM slots.

In reality, this means you can still make a build with up to 32GB of storage which is plenty for gaming and most other functions.

Of course if you’re focussed on the best speed possible, more slots will help.

Not just because of the increased overall storage, but more RAM sticks are marginally more effective than overall storage (e.g. 4 x 8GB RAM is better than 2 x 16GB RAM for most users).

We wouldn’t worry about RAM compatibility too much unless you’re running some high-quality production/editing/streaming computer.

Gaming PCs won’t need more than 32GB for a while.

If you do have specialist requirements, high-end E-ATX/ATX motherboards include up to 8 RAM slots/256GB capability!

I/O Panel

Motherboard IO PanelThe features available in an I/O panel will typically increase not just with chipset (which allows your mobo to support more inputs, e.g. USB 3.1 type C) but also the size.

E-ATX/high-end ATX motherboards often have a host of great ports available.

Smaller motherboards will usually have the standards though (some USB/audio ports) but check that your choice will have what you need, or you have a suitable extender.

Extra features

Finally, there are all the extra bells and whistles motherboards can come with.

The most common ones are:

  • Integrated sound card
  • Integrated network card (Wi-Fi/ethernet)
  • Integrated Bluetooth (if not, adapters are dirt cheap)

Typically, larger motherboards include more of these features as it’s easier for the manufacturers to add.

We would say it’s often preferred to buy a standalone sound card or network card if you have PCIe slot room (not essential if your budget is tight, though).

Even Mini-ITX boards can come with these features integrated, just know that you may not get quite the same quality as large integrations or standalone cards.

That being said for smaller builds, we’d recommend getting integrated versions of features you need where possible so you’re not having to use your very finite USB/PCI inputs.

Which Motherboard Should you get?

Best budget gaming motherboard

If your focus is on affordability above all else, go with Micro ATX.

While you may not get the same features as E-ATX/ATX you’re not going to need them for a cheap build.

Things like excellent cooling/space for multi-GPU builds aren’t so important for a cheap gaming PC where you should be focussing on 1 graphics card.

Micro ATX builds are the perfect balance between being small enough for good mobo/case affordability while not so small that you have to fork out more money/effort for “specialist” small parts.

Our best cheap gaming motherboard picks:

Best mid-range gaming motherboard

For most builders, the sweet spot is an ATX motherboard for gaming.

With all the feature a large majority of builders need, good space for parts/cooling in their compatible cases, and lots of choices, ATX mobos are perfect for most setups.

Even if you don’t need every PCIe/SATA/RAM slot, know that having an ATX case/motherboard gives your parts more room for ventilation (and makes the build process easier).

Our top picks for the best ATX motherboard:

Best high-end gaming motherboard/production PC

Now let us be clear: the options above will be enough for a majority of readers.

But, if you’re less concerned with budget and more with creating the most powerful PC you can, then you want to look at an E-ATX motherboard.

These will give you the most space and utility possible with no compromises made for compactness.

This is what makes them appealing not just for gaming, but for someone looking for the best production PC possible (video editing, rendering, etc).

Not to mention the large cases that come with the most room for cooling, drives, and ease-of-build.

In fact, even if you wanted an ATX motherboard for your high-end build (also doable), we’d recommend looking at E-ATX full tower (or “super tower”) cases for the best airflow/cooling options as long as you don’t mind the size.

Our top picks for the best E-ATX motherboards for gaming:

Best small motherboard for portable/HTPC build

Finally, there are those after the smallest motherboard for a portable build or HTPC.

It will come as no surprise that Mini ITX motherboards are the best option for you if this is what you’re hunting for.

Yes, as we’ve discussed, you’re losing out on some hardware compatibility and other features with a PC this small.

But combined with a high-quality case and some consideration for which parts you’re going to buy (ensuring they fit), you can still create a gaming PC capable of LAN parties or streaming.

Our top picks for the best Mini ITX motherboard:



XL-ATX motherboards are another form factor that traditionally are a similar width to E-ATX, but a bit longer.

We’ve chosen not to include them in our guide for a couple of reasons:

  • This size type is super uncommon and the options available aren’t great.
  • The use-cases are incredibly specific, given you can build anything from a powerful server to gaming PC on an E-ATX mobo, we’d wager XL-ATX isn’t necessary for anybody reading this.
  • Similarly to “full tower vs super tower”, XL-ATX is loosely defined and is a marketing term as much as it is a legitimate form factor. A lot of “extra-large motherboards” are E-ATX or even ATX anyway.

Short answer: don’t worry about Xl-ATX.


What order should I pick PC Parts?

Reading this guide and the criteria for selecting a motherboard, you may be confused as to how you should build your PC (e.g. do you pick a compatible motherboard for your chosen CPU or vice versa?).

It’s a bit of a “chicken and egg” situation, there’s no “right” order to pick parts in.

But here’s the outline we would recommend for most gamer builds (from first to last):

GPU – > CPU – > Motherboard – > Case – > RAM/storage/extras – > PSU

Don’t think that the above also represents order of importance, a PSU is very important!

It can just make sense to pick it last once you know the power requirements of your PC/what size PSU will fit in your case.

It all starts with the motherboard.

Nowadays, the market for this foundational part is so competitive, manufacturers have come up with new ways to add value to their latest versions.

Luckily for us builders focused on a beautiful PC, the big emerging trend is now the inclusion of RGB lighting within the motherboard, and lots of RGB header availability to light up your PC subtly, or make it look like a glowworm cave.

Not all the options available are great though, which is why we’ve collated the best RGB motherboards available on the market and categorized them for your varying needs.

 Table of Contents

Quick Tip:

RGB builds look great in cases with lighter colors/more windows. The reflective surfaces/increased visibility can really add to the effect. Check out our write-up on 15 best lighter cases.

Anyway, let’s get to it:

Best Intel Motherboard Overall: Asus ROG Strix Z390-E

This one is popular for a reason!

Asus has created what we think is the best RGB gaming motherboard for LGA with the Z390-E. Filled with fantastic features at a competitive price point against many of the other Intel offerings.

Let’s talk about the RGB utility. To start, you have a gorgeous LED ASUS logo and “cybertext” shining across the I/O panel. Which combined with the 2 x RGB headers and 1 x addressable RGB headers available on the board, gives you fantastic customization options when installing additional LED strips on your case.

What gives Asus the top stop from an RGB perspective is the Aura Sync software. With an incredibly wide compatibility range to other LED parts (be it cases, fans or GPUs) and a multitude of different effect options (anything from rainbow color cycles to lighting in beat with the music you’re playing). It’s hard to get a better base for your next crazy RGB PC build.

But the board isn’t just about being a light show. Featuring 4 x DIMM (DDR4 compatible) RAM slots, LGA 1151 socket for Intel gen 8/9 processors, and 2 x PCIe 3.0 (x16) / 1 x PCI-e 3.0 (x4), the board has everything you need for a powerful multi-GPU setup should you desire. Also coming with a bunch of quality software and onboard utility that will expand your ability to effectively overclock your CPU and GPU.

And to round up is the set of great features available through the beautiful I/O port. Excellent HD-quality audio is outputted via an S1220A codec SupremeFX chipset; which surpasses what many independent sound cards achieve. Not to mention Gen2 802.11AC wi-fi (and Bluetooth) capability. And of course, it includes all the usual ports you will expect to see with a nice addition of USB 3.1 Type C.

If this board fits in your price range and you’re looking for the best RGB motherboard for gaming, you’ve found the one.

Best Intel Motherboard Runner-Up: Gigabyte Z390 AORUS MASTER

This may not be our number #1 pick, but it sure is a good second place.

Boasting a very flashy set of LEDs across the logo, bottom left shroud, top right small logo, and I/O panel; this option certainly has some of the most onboard LED display out of the options in its price range (if you’re looking for RGB abundance).

The MASTER comes with multiple RGB LED headers and the RGB Fusion 2.0 software, a very respectable competitor in features to ASUSs’s Aura sync.

Aside from that, the motherboard is also well equipped for your gaming/production needs, with 4 x DIMM, intel 8th/9th gen support, and 3 PCI-e 3.0 x16 slots.

There’s a host of additional nice quality-of-life utility to this board. To name a couple of highlights: there are nice additional durability features for some of the case’s ports (particularly for the GPUs where this can be a problem), alongside an onboard thermal guard solution for your overclocking requirements.

The included ESS SABRE DAC ES9118 chipset will arguably provide the best high-quality audio of all RGB motherboards outside of the high-end options. With a wi-fi offering similar in quality to our top pick. The I/O panel includes everything you’d expect with USB 3.1 Type C.

Overall, if you prefer the style and feature offering of the Z390 over our top Asus choice, don’t fret: we’re still confident this board will be a fantastic choice for your RGB PC build.

Best Intel Budget Choice: ASRock B365 Phantom Gaming 4

This may seem a tad pricey for a budget pick, but this can be common for Intel motherboards. And truthfully, while there are cheaper LGA RGB options available, we simply can’t recommend any of them.

That being said, the B365 is a fantastic choice for someone looking for RGB style without reaching too far into their pocket. With some gorgeous RGB illumination on 3 parts of the board (logo, I/O panel, and underneath) + 1 x addressable and 2 x standard RGB LED headers, you have an impressive amount of lighting available here for the price.

ASRock also has its own software for lighting customization with Polychrome Sync. While not as highly regarded as some of the other offerings here, it’s still got all the central utility you’ll need to configure many interesting lighting formations.

The general features of the motherboard are decent. With 9th/8th gen intel support, 4 x DDR4 DIMM slots, 2 x PCI Express 3.0 x16 Slots, and the usual I/O ports included. The onboard sound won’t be quite as good as the other top offerings but for most users, it’s still going to give you the performance you need.

If you (and your wallet)  like the look of the ASRock B365, then know you’ve still got everything you need here to set up an ambitious budget gaming PC build. The same goes for VR, streaming and production.

Best Intel High-End Choice: ASUS ROG Rampage VI Extreme Omega

With a price as long as its name, the Rampage VI Extreme Omega is a beast of a motherboard (this being the hardest category on the list to decide, with 2 other fantastic options available: MSI MEG Z390 ACE & ASUS ROG Maximus XI ).

If the price isn’t a barrier for you, this is the best RGB motherboard you’ll find for Intel builds.

Firstly, the RGB utility: you’ve got some of the most gorgeous inbuilt lighting from the get-go with the large ASUS logo, I/O panel strip, and underside of the motherboard glowing from Aura Sync-controlled RGB lights. On top of that is the 1 x addressable and 2 x standard RGB headers. Combined, you’re going to have some fantastic, customizable case lighting.

Then there’s the general feature set and build quality. Which is pretty much as impressive as you can imagine and too quantitative to go over here. But to name a few highlights:

  • A fantastic array of onboard temperature control (from an aluminum heatsink surround the PCIe M.2 expansion slots to the DIMM.2 cooling).
  • Top range Intel Wireless-AC 9260 for high-performance wi-fi.
  • An I/O panel with more USB ports than you’ll ever need (including a USB 3.1 type C input) and illuminated LED audio ports powered by the fantastic SupremeFX S1220 CODEC.
  • 8 x DIMM slots, supporting a maximum of 256GB DDR4 RAM (this would be quite the build for video editing or high-end production).
  • Livedash screen: see the area on the I/O panel underneath the LED strip? That’s an OLED screen that you can customize to display the things you want to monitor most.

The list truly does go on, this board has been designed to provide the best overclocking facility available today.

If you’re looking for the best RGB motherboard money can buy for a multi- GPU build alongside other very demanding components; then provided your wallet can handle it, this board is going to blow you away.

Best AMD Motherboard Overall: MSI B450 Gaming PRO Carbon AC

If I had to pick the most impressive board on the list with consideration for price, this would be it.

Let’s start with the RGB: The board has two beautiful in-built RGB lights, one shining under the MSI logo and one under the board itself. If you’re thinking this may look more “understated” than some of the other options, know that once you have your shiny/bright CPU cooler, GPU and RAM in, some of the onboard lighting can become harder to see, so having light directly underneath is a great way for the presentation to still shine through.

For RGB customization, the PRO Carbon AC comes with 2 x 12V 4 pin headers and a 1 x 5V 3 pin header. Giving you great options for further lights on top of the existing ones. All of this can run through the Mystic Light Sync software, a similar offering to ASUS and Gigabytes offerings that allows you to customize and add cool effects to your LEDs.

Of course, we’re not just here for the RGB. At a fantastic value point, you’re getting support up to Ryzen 9, 4 x DIMM slots for DDR4 RAM and a host of quality-of-life features to allow for more effective overclocking.

One thing to point out is the lack of a third PCIe x16 slot. It’s perfectly suitable for a crossfire setup and we expect for a large majority, having only 2 slots will not be an issue, but if you need to use a high amount of PCIe x16 inputs, you may want to look at our runner-up choice (or really the high-end choice if you’re trying to run some 3+ GPU setup).

The onboard Audio Boost 4 processor will provide you with great sound through the available outputs (and some great onboard software to get exactly what sound optimization you’re looking for). Accompanying them on the I/O panel are the standard ports, with plenty of USB/display options and very impressively for the price point, a decent onboard wi-fi adapter.

Reading through this, I’m sure you’ll see why we’re so excited about the PRO Carbon AC. MSI has really created a fantastic option here and if it meets your desired RGB style, component requirement, and price point, then we can’t recommend it enough.

Best AMD Motherboard Runner-Up: ASUS ROG Strix B450-F

Closely in second place is the AMD version of our top pick for Intel.

With the same very sleek LED logo in the top left I/O panel and two RGB headers on board, you still have great options to work alongside the fantastic Aura Sync software.

The reason this board didn’t take the same top spot as it did on the intel side is the lack of addressable RGB header and the slick “cybertext” logo also isn’t an LED in this version. This is likely due to the generally lower price point of AMD motherboards.

Aside from that, you have largely the same fantastic offering here for the AMD side: with 4 x DIMM dual-channel RAM slots, AM4 socket for 1st/2nd generation Ryzen chipsets, and 2 PCIe 3.0 x16 / 1 PCIe 2.0 x16. With a host of great onboard features if you wish to overclock.

The I/O panel is standard with everything you’d usually expect, this specific motherboard doesn’t have wi-fi inclusion (and is lower in price as a positive result) but does include the fantastic SupremeFX S1220A CODEC chipset for excellent high-quality audio.

If the Carbon AC doesn’t catch your eye, we love this ASUS offering and would be a fantastic foundation for an RGB gaming PC.

Best AMD Budget Choice: ASRock B450 Steel Legend

While we’d recommend spending a little more to get the MSI PRO Carbon AC,  this is still a great option for an AMD PC build.

The RGB options here are brilliant for the price. We have the addressable LED lights on the I/O panel and underneath the logo, as well 1 x addressable and 2 x standard RGB headers, plenty for nearly any RGB build and with ASRock’s Polychrome Sync software to customize them to your desire (not quite as good as the ASUS/MSI software but still perfectly decent).

The board includes the usual DIMM DDR4 slots, AMD AM4 socket, and 2 x PCIe 3.0 x16 slots. While not as feature-dense for overclocking as the other models above, you still have some onboard utility that puts it above a standard motherboard.

The I/O panel is also great for the price, with 6 USB 3.1 ports (including 2 x gen 2) amongst the other standard ones. While not the best on the list, the onboard audio will satisfy most.

As far as buying a cheap RGB motherboard goes, this is one of the best value offerings you can find if you’re not looking to spend a little more on the MSI PRO Carbon AC and still has everything you need for a cheap gaming build.

Best AMD High-End Choice: MSI Prestige X570 Creation 

Just look at this thing.

Aesthetic is just one of the many areas the Prestige X570 excels at (there is little it isn’t good at, except friendliness with a budget!).

Firstly, this is the only AMD motherboard on the list that fits into the E-ATX form factor, giving you optimal space for your build if compactness isn’t a concern for you.

For the RGBs, you have stylish LED strips running across the I/O panel, and lighting underneath, both powered MSI’s great Mystic Light software; which will also give you control over the 1x 4-pin RGB, 2x 3-pin Rainbow & 1x 3-pin Corsair LED connectors available on the board (between these headers and the onboard lighting, you have the best options available on the market for an AMD RGB PC build).

The other quality-of-life features across this motherboard are fantastic. Anything from steel protectors around the PCIe ports to protect your beefy GPUs, to the auto-adjust Frozr heatsink designed to maximize the cooling/overclock potential for the best gaming PC build possible.

With top-tier wi-fi, audio quality, and the highest amount of USB ports and types on the list, the rear I/O panel is also second to none.

Simply put, if you’re building an AMD RGB PC build and want the best performance possible, you’ll be hard-pressed to find anything that comes close to competing with the X570 Creation.

Best Micro ATX Motherboard: MSI MPG Z390M Gaming Edge AC

If you’re looking at Micro ATX/Mini ITX RGB builds, there unfortunately isn’t a crazy amount on the market we’re willing to recommend right now (which is why this list only features Intel options for these categories).

That being said, thankfully the MSI MPG Z390M exists! It’s crowning feature from an RGB perspective is having both 2 x 4-pin RGB LED and 2 x 3-pin RAINBOW LED connectors onboard, fantastic for an mATX motherboard; combined with the inbuilt addressable RGB lighting underneath the board, you’re going to have plenty of lighting utility to brighten up an RGB mini tower.

The motherboard includes 8th/9th Intel processor support with its LGA 1151 socket, 4 x DIMM DDR4 RAM slots, and 2 x PCI-e 3.0 x16 inputs (you’re unlikely to need more for a mini-tower).

The I/O panel and additional features are good, with USB 3.1 Gen 2 ports, high-quality audio (not the best on the list but still great for the average user), and an Intel Wireless-AC 9560 giving the motherboard great onboard wi-fi (Bluetooth included).

If you’re looking to create a Micro ATX RGB PC, this is without a doubt the best motherboard to do so. If you’re really desperate for a Micro ATX RGB Motherboard for AMD, then check out the AsRock B450m.

Best Mini ITX Motherboard: ASUS ROG Strix Z390-I

Another ASUS ROG Strix board came out on top for our smallest form factor today.

It’s very impressive how many of the features are still crammed into this thing from the full form factor-sized models (accepting of course, that there are some removals).

The included RGB LED lighting shines underneath the back of one whole side of the board and is accompanied by 1 x addressable / 1 x standard RGB header connectors. This is all controllable through ASUS’s fantastic Aura Sync software. It’s hard to imagine you needing any more lighting in a tiny build like this!

The board boasts what you would expect for CPU and RAM, with an LGA 1151 socket and4 x DIMM DDR 4 slots. There is only one PCI-e 3.0 x16 slot. This is standard for mITX, and I’m assuming you’re not looking at SLI or Crossfire in such a tiny RGB build!

Covering a huge portion of the board is a VRM heatsink/thermal pad. This is going to be great to manage cooling in such a compact build, where the lack of space/airflow can often cause problems in gaming /production rigs.

That board also includes a fantastic SupremeFX S1220A CODEC audio unit, Intel 9560 wi-fi adapter, and a good amount of I/O ports for the size of the board.

For the tiny form-factor AMD builders out there, there’s also the AMD equivalent ASUS ROG Strix B450-I too (with some slight variations in specs but still a great option)!

Overall, we’re really pleased to see that ASUS has created an mITX version of the Strix series that still feels nearly as impressive as its larger counterparts. We think you’ll love picking this up for your RGB Mini ITX build.

Honorable Mention: MSI MPG Z390 Gaming PRO Carbon

While not quite getting one of the top spots, this item was effectively 3rd place in the “ATX motherboards with RGB lights” category. We wanted to round off the list with an option we would still recommend if it better aligns with your style, price range, or hardware requirements (with an AMD version available too).

The PRO Carbon includes subtle lighting against the I/O panel and underside of the board, alongside the option to extend your RGB LED lights with 2 x 4-pin RGB, 1 x 3-pin Rainbow & 1 x 3-pin Corsair LED connectors. The biggest reason we wanted to include this on the list is that this amount of RGB headers included for the price is impressive and would give you a lot of customization options (especially working alongside the MSI Mystic Light software).

The case is great in the standard areas too, with 4 x DDR4 RAM slots, coffee lake CPU support & 3 PCIe3 x16 slots. The I/O ports being relatively normal but including good onboard audio also.

If you’re a fan of MSI, the board style, or anything else that is shifting you towards this, don’t be put off for it not getting a top recommendation; we’ve added it for a reason. It’s still a great base for an RGB PC.
