SFF PCs are the new craze. And, if you’re also building a micro-ATX PC, then do not go anywhere without reading this article because this is for certainly you! Today, I have reviewed the best micro ATX motherboards that will take your mATX build to a whole new level of performance. Along with that, i have answered some of the frequently asked questions on what makes up a good micro ATX motherboards as well. So, let’s begin!

The idea of making small form factor PCs has taken over the geeks in the past few years. And, if I am not wrong you’re one of them 😛 Well, me too. Do you know why? Actually, this shift has come because the standard ATX motherboards are becoming more advanced and consequently costlier.

And, a smart consumer always chooses what fulfills his needs while fitting well in budget. Here comes the micro-ATX motherboard (also called mATX motherboards for short.)

An mATX motherboard includes all the necessary ports and slots on a fairly smaller PCB and it comes at a cost much lower than the advanced ATX mobos. The only thing you lose is a couple of expansion slots which, by the way, are generally left empty unless you are a serious professional.

So, technically a micro ATX motherboard is a good choice with a perfect balance between size, performance and cost as well.

Choosing the best micro ATX motherboard among so many different options can be a daunting task because I have been through that process very recently. So, I decided to write this comprehensive post to help you find the perfect mATX motherboard in 2019.

Recommended: Buying a micro ATX motherboard? You will need a good micro ATX case for that. Check out our list of best Micro ATX Cases you can buy in 2019.

How to Choose a Perfect Micro ATX Motherboard?

Having seen all the options, choosing a single one can be a task. And, the most frequently asked question about the micro ATX motherboards is “how to choose the perfect micro ATX motherboard”.

Let solve the mystery for you – All mATX motherboards are Perfect!

Yes, the only thing that matters is what are your requirements and budget. In the list of mATX motherboards above, I have included all type of options. Therefore, before you buy any micro ATX board, check out the important factors that make up a good mATX motherboard.

Number of RAM Slots

You must have seen that many budget mATX motherboards come with two RAM slots while mid to high-end boards have four RAM slots on board. So, the common question is which one to go with – two slots or four slots?

See, if you take my advice, go for an mATX mobo with four RAM slots. It gives you scope for more memory even if you are currently running two RAM sticks. Instead of choosing an mATX motherboard with two RAM slots, why not go with mini ITX that has two slots for RAM and cuts the build size by large.

Number of Expansion Slots

The number of expansion slots on a Micro ATX motherboard can vary between 2 to 4. They are meant for different integrated features like video cards, audio cards, and networking. More than the number of slots, the type of expansion slot matters.

PCIe 3.0 x16 are the latest and fastest expansion slots nowadays. In case you have any old expansion cards, then you may want to opt for PCIe 2.0 x4 / x1 slots to use them.

Two PCI Express x16 slots are enough for most users but at least one is necessary to have a discrete graphics card on board. With two slots you can opt for a multi-GPU setup with Nvidia SLI / CrossFireX support.

Type of SATA Connectors

You all know what SATA connectors are for – to connect storage like hard drives, optical drives etc. Most mATX motherboards will have at least four SATA 3.0 connectors that can run at 6Gb/s. Always go with four or more SATA 3.0 ports if you want to have a couple of internal hard drives plus an optical drive.

Also, if you want to take advantage of faster M.2 Solid State Drives, make sure you have at least one M.2 NVMe connector because M.2 SSDs do not run off the PCIe x16 or SATA ports.

Overclocking Capability

This is for more high-end users (the geeks I mean 😛 ). See, if you are eyeing to overclock your CPU it is going to consume more power. And, for the same, your mATX motherboard should have more power phases to deliver cleaner and stable power to the overclocked CPU.

Having more power phases also means less load on motherboard transistors, thus, increasing the lifespan of the motherboard. If you intend to overclock your CPU and RAM on a micro ATX motherboard, there must be at least a 4 + 2 power phase; in fact, a 6 + 2 is what I would recommend. 4/6 here is the number of phases for the CPU while 2 refers to the number of phases for the memory (RAM) controller.

Please note that for all that overclocking you must have a high-quality VRM otherwise no matter what power phases you have, it is going to fry your micro ATX motherboard. For reliable VRMs, I recommend brands like Asus, Gigabyte, ASRock, and MSI.

Connectivity Options

Among other things comes the connectivity and for that, the most important thing is USB ports. Always choose an mATX motherboard having at least USB 3.0 ports while having USB 3.1 is recommended. You can see a huge difference in data transfer rate (up to 6 times) when using flash drives via USB 3.1 instead of older USB 2.0.

Another important factor to look for is the number of fan headers. Because mATX is smaller than ATX, they tend to heat and for that, you are going to need a good cooling system in place. The number of Fan headers determines the no. of case fans that you can install.


FAQs about Micro ATX Motherboards

I know there are always some doubts and that why I am sharing my answers to some of the most common questions that users ask frequently. These will help you understand micro ATX motherboards and make a better choice.

What does mATX mean?

The meaning mATX is “Micro Advanced Technology eXtended” which is the smaller version of standard ATX form factor. It is also known as Micro ATX. The size of an mATX motherboard is 9.6″ x 9.6″.

Can a micro ATX motherboard fit in a mid tower case?

Yes, any micro ATX motherboards can easily fit any mid-tower case which supports a standard ATX form factor. All you need to do is align the motherboard into the correct mounting pegs and it will fit right in.

What’s the difference between a micro ATX and ATX motherboard?

As the name suggests, a standard ATX motherboard is larger than a micro ATX motherboard. With more space on the board, ATX mobo can have more PCIe expansion slots, SATA connectors, RAM slots etc. On the other hand, micro ATX motherboard is compact, has lesser expansion slots and also requires components of appropriate size to fit correctly. Read more about the difference between mini ITX, mATX, and ATX.


Conclusion: The Best mATX Motherboard 2019

Well, that’s all in this roundup of micro ATX motherboards. I believe it must have helped you to make an informed choice while buying an mATX motherboard for your new PC build.

In the end, for those who are still in the dilemma of choices, let me highlight my personal recommendations once again.

In Intel section, the gamers who want a balance between performance and budget, just buy the Asus ROG Strix B360G – the overall best micro ATX motherboard of 2019. If you want a more affordable option, please go with Gigabyte B360M which is the best budget micro ATX motherboard.

While there are not many options to choose in the AMD section but if you want the best micro ATX motherboard for AMD, buy the ASUS Prime A320M-K.
