Best Micro ATX X370 Ryzen Motherboards 2018

Ryzen has been out for over a year now, and finally, motherboard manufacturers have released Micro ATX X370 motherboards for the AM4 socket. Since the performance of the B350 and X370 has proven to be nothing short of amazing, we’ve seen an influx of market share go to AMD over this time. Luckily we’ve got SLI support and a plethora of great features on these motherboards from ASRock, Asus, MSI and more. So let’s dive into the specifics and what makes for the absolute best micro ATX X370 Ryzen motherboards…

You can find current-gen Ryzen processors going for super good deals. Also, AMD already dropped Ryzen prices in January, then pushed them down, even more, this month. Now, costs have plunged yet again for two mainstream models if you’re willing to fill out rebate forms. It’s a great time to buy into Ryzen AM4, even if GPU prices are still very inflated (hopefully this changes sooner than later). Here are what we think are the best Micro ATX X370 Ryzen Motherboards 2018:

What is a Motherboard?

Chances are, if you are researching something this deep, you already know this, but it is still worth addressing. A motherboard is typically thought of as the “backbone” of a computer. It is a essential piece of hardware that allows the computer to run. All of the components inside of the computer are connected to the motherboard. This allows them to communicate with each other and do their job.

This includes video cards, sound cards, hard drives, optical drives, the CPU, RAM sticks, USB ports, a power supply, etc. On the motherboard are also expansion slots, jumpers, capacitors, device power and data connections, fans, heat sinks, and screw holes.

B350 or X370 MicroATX?

So lets get to the point. There are very few MicroATX X370 motherboards. In fact, there is only one. However, unless you want to run SLI/Crossfire you lose nothing by sticking to B350. If you need to run SLI, strangely enough there are some great ITX options to choose from. Why motherboard manufacturers decided to skip over mATX for the x370 chipset is beyond me. If you need a list of ITX options, see here.

If you are hell-bent on using Micro ATX X370 with ryzen, another option is to move up to X399 and thread ripper. ASRock has a fantastic high-end X399 option, but it’s not cheap, unlike our Best gaming mousepads.

AMD Ryzen 2000 Series

As AMD has promised, the Ryzen 2000-series CPUs will fit into the exact same AM4 CPU socket in the 1000 series Ryzen processors. Though there will be a new set of 400-series chipsets. What this means is if you pick up a X370 or B350 today, you’ll be set to drop the new Ryzen processors without issue.

So what is the difference between X370, B350, X470, B450?

Pugetsystems made a nice chart outlining the differences and think it’s worth highlighting.

Micro ATX (mATX) Motherboards and Why to Downsize?

While the focus has been on full ATX motherboards, we thought it prudent to give an overview of the smaller form factor Mobos for those of us who love smaller form factor cases. We lose out on a few features like additional USB ports, possibly fewer memory slots, less PCI slots and a few SATA ports. But, for a lot of us we don’t really use them all anyway.

Whichever the reason may be, you’re here for details on which mATX motherboard is the best for you. So let’s break down some of the best Micro ATX X370 motherboards out on the market.


Best Micro ATX X370 Motherboards

Due to the limited number of AM4 mATX motherboards, we will be limiting our list to the top 3.

High End | ASUS TUF B350M-PLUS GAMING

TUF B350M-PLUS GAMING matx

I thought that maybe ASUS had finally gone and abandoned the idea that the ASUS TUF motherboards being superior compared to the other options, I was wrong.

The TUF B350M mATX board has a fairly nice heatsink over the vrm’s and has a quiet 80mm fan to boot. Moreover, the integrated network controller is great! The board is quite heavy for its size but is made with high-end components so it makes sense.

With many features like “Fan Xpert 2+” and high-end PCIe retention shields, this earns its title as the best mATX x370 Ryzen motherboard.

Other notable specifications for the ASUS TUF B350M-Plus Gaming include:

4 xDDR4 3200(O.C.)Realtek ALC887 Audio
6 x SATA 6Gb/s PortsRealtek RTL8111H LAN Chipset
AURA Sync RGB Lighting2 x USB 3.1 Gen 2
M.2 Support
Both SATA & PCIE mode
4 x USB 3.1 Gen 1
1 x Fan RGB header2 x USB 2.0
Front USB 3.1 Gen 12 x Chassis Fan connector

More Info

ASUS brings a lot of functionality with the TUF lineup and the price is honestly reasonable. Now, You don’t see the $400+ price tags like you would on their high-end mATX motherboards. But, you still get every feature you should need especially for such a reasonable price point.

SafeSlot is the name ASUS gave it’s PCIe slot retention, and its engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points. Or so they say…

A few other points worth note:

  • AUDIO SHIELDING
    Separates analog/digital signal domains, significantly reducing multi-lateral interference.
  • DEDICATED CHANNEL LAYOUTS
    Separate layers for left and right channels to guard the quality of the sensitive audio signals.
  • AUDIO ENJOYMENT
    Premium Japanese audio capacitors provide warm, natural, and immersive sound with exceptional clarity and fidelity.


Mid Range | GIGABYTE GA-AB350M-Gaming 3 Micro ATX

Budget | ASRock A320M PRO4 mATX

ASRock A320M mATX Motherboard review
The budget-friendly ASRock A320M PRO4 X370 mATX motherboard can pack quite a bit into a small budget. There isn’t currently much more you can ask for at such a small price. For example, this motherboard comes with dual m.2 SSD’s. One PCIe Gen3 x4 Ultra M.2 interface that pushes data transfer speeds up to 32Gb/s, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSD. And the other one supports SATA3 6Gb/s M.2 modules.

Another great feature of this board is the software package that it comes with. ASRock has a surprisingly useful array of software in the APP Shop. ASRock APP Shop is an all-in-one utility designed for system update and software downloading. It is integrated with a variety of applications and support software. The ASRock APP Shop provides the latest BIOS updates and system upgrade software for users to download. You can easily optimize your system and keep your PC up-to-date with it. Also, APP shop is geared up with numerous popular PC games. You can also receive exclusive bonuses, in-game items. Not too bad.

A few notable specs on the ASRock A320M PRO4:

4 xDDR4 3200(O.C.)Realtek ALC892 Audio
4 x SATA 6Gb/s PortsRealtek 8111GR LAN Chipset
Support for APP Center1 x USB 3.1 Gen1 Type-C Port
M.2 Support
Both SATA & PCIE mode
4 x USB 3.1 Gen1 Ports
1 x Fan RGB header2 x USB 2.0
Front USB 3.1 Gen 12 x Chassis Fan connector

The PRO4 might not be the best micro ATX X370 motherboard but it gives you the best bang for your buck. However, You cannot argue with the features and build quality provided at this price point. If you’re not looking for extreme overclocking capabilities and don’t necessarily need the software included in any of the ASUS boards then you might want to settle for the PRO4.


Conclusion

With the upcoming release of the Ryzen 2000-series CPUs, and the new Nvidia GPUs coming in the summer, now might be a great time to pick up a new X370 mATX motherboard. So, While the next few months, the upcoming 400 series mobos might be released, they undoubtedly will come at a steep price.

Overall, we look forward to seeing whats next for motherboard manufacturers this year and will update this guide of the best micro ATX X370 motherboards as we move forward. In the meantime, check out one of our other articles, we recently compiled a list of the Best Micro ATX Z370 Ryzen Motherboards and you might find a gem in there.
