How We Choose the Best Mini-ITX Motherboards

Mini-ITX motherboards are a niche product so one has to consider certain factors before buying a board of this form factor. Similarly, we made sure we selected motherboards that fulfilled certain criteria.

Firstly, we only selected motherboards that used relatively modern Intel and AMD chipsets. The oldest chipset we selected was the Z390 Intel chipset, due to the popularity of the Core i9 9900K.

The power delivery setup of the motherboard was our priority, especially in flagship chipsets such as X570 and Z690. Even mini-ITX motherboards should be able to overclock the high-end CPUs that they support.

We also laid focus on the feature-set of the particular motherboards relative to their chipsets. Connectivity and storage were the primary things we looked at, with additional features such as high-speed USB, Thunderbolt, additional PCBs, etc. being counted as bonuses.

The number of M.2 slots and expansion slots was given priority since that is the main area of concern with mini-ITX boards.

The MSI MPG B560I Gaming Edge WiFi should be on your priority list if you plan to build a smaller gaming PC with 11th Gen Intel processors. The B560 chipset is a mid-range chipset that does not support overclocking, so its offerings are budget-oriented as compared to the flagship Z590 chipset.

Since it is a budget-oriented motherboard that doesn’t support CPU overclocking, the VRM design is less important. However, it still should be able to handle power-hungry CPUs such as the Core i9 11900K.

Thanks to a satisfactory 6+2+1 phase VRM setup, it should be capable of handling the 11900K at stock settings.

However, due to differences in their price brackets, it doesn’t make a lot of sense to pair an overclocking flagship CPU with a budget motherboard with a locked multiplier. The Core i7 11700 or the Core i5 11600/11400 seem to be more appropriate pairings.

The feature-set of the B560I Gaming Edge WiFi is actually quite impressive relative to its price tag. You get the option of 2.5 GbE LAN and WiFi 6E which are both welcome features in terms of connectivity. For storage, there are two M.2 slots and 4 SATA ports, another great addition by MSI to this mid-range motherboard.

For more budget motherboards, you can also take a look at the best budget X570 motherboards if you are on an AMD system.

There are some complaints, however. The audio codec in the board is quite mediocre, and the number of USB ports on the back might not be enough for some users.

In terms of aesthetics, RGB lighting is missing from the board, which might be a bit of a letdown for some users. However, this board should be right at home in a workstation PC or a stealthy black gaming PC build.

Overall, the MSI MPG B560I Gaming Edge WiFi might just be the best B560 mini-ITX motherboard on the market. It is also quite affordable, so you should definitely consider it if you want to build a compact gaming PC featuring Intel 11th Gen processors.

If you are rocking a 3000 series or 5000 series Ryzen CPU, then you might want to consider the Gigabyte B550I AORUS Pro AX – WiFi. This is the best B550 mini-ITX motherboard on the market and should be ideal for a compact PC gaming build. The B550 platform also provides support for the PCIe Gen 4 protocol through one of the M.2 slots.

The B550I AORUS Pro WiFi is quite a premium motherboard and it has a premium VRM setup to back it up. Since B550 allows CPU overclocking, the robust VRM can come in quite handy if you want to overclock your Ryzen 7 5800X or even Ryzen 9 3900X CPU.

We would, however, advise against pairing Ryzen 9 parts with this motherboard as the VRM cooling is not excellent under extended loads.

For that purpose, you can use the best motherboards for Ryzen 9 3950X that we recommend.

Gigabyte has provided 2 M.2 slots under a massive M.2 heat spreader in this board, which is a welcome touch. Only one of these M.2 slots can provide PCIe 4.0 functionality, however, but that is a limitation of the chipset itself.

When it comes to looks, the B550I AORUS Pro is fairly mediocre in our subjective opinion. The VRM heatsinks are large and plain, which does not really fit in with the aggressive AORUS design language.

All things considered, the Gigabyte B550I AORUS Pro is a solid mini-ITX option if you want to go with the B550 platform.

It is quite expensive, however, and there are some ATX X570 options on the market that are better-equipped in a similar price category if mini ITX is not necessery. As with any tech product, you should do your due diligence before pulling the trigger on this one.

Best Mini-ITX Motherboard – Buyer’s Guide

If you have a mini-ITX case and are ready to build a mini-ITX compact PC, then you need to consider some factors before buying the right mini itx motherboard for you. Mini-ITX motherboards are a bit more complex to shop for since they have a unique shape and size.

Dimensions

First of all, you need to consider the dimensions of your chassis. Many mini-ITX PC cases come with a standard motherboard tray that can hold any mini-ITX motherboard, but some cases are uniquely designed to only fit certain motherboards. Check the dimensions of all components before making the final decision.

dimensions of your pc case chassis

GPU Compatibility

The problem is not with the size of the motherboard itself (which is standard), but with the components you’ll attach to it. Make sure your graphics card fits on the motherboard and does not touch any case components. Make sure the fan headers for the graphics card have access to cool, fresh air.

CPU Cooler Fitment

You should also consider the size and height of your CPU cooler. Many mini-ITX cases will not allow you to install any standard air cooler to cool your AMD or Intel CPU or whatever CPU socket brand you use. There are special SFF CPU coolers that are made for these cases.

CPU Cooler Fitment

Limited Amount of DIMM Slots

Mini-ITX motherboards have to make some sacrifices in order to attain that small form factor. Many of these sacrifices are achieved by reducing the number of storage features.

It is common for mini-ITX boards to have only two DIMM slots. That is understandable, but you must consider that you cannot upgrade your memory down the line if you buy a mini-ITX motherboard.

Connectivity

In terms of connectivity, you should consider the number of M.2 slots and display port options on the board. It is hard for manufacturers to include more than 2 slots on these boards , and some might only have 1 M.2 slot.

The compact boards might also have fewer connectivity features. Due to their pricing, they may have worse connectivity features than competitive ATX motherboards. So keep an eye out for these sorts of limitations when building your mini-ITX PC.

Cable management, Intel Gigabit ethernet, and things like having eight SATA ports, or even four SATA ports on such a small form factor can be difficult. Most m-ITX motherboards in 2022 include dual channel RAM options and things like Wi Fi.

Expansion Options

Another thing you should consider before buying a mini ITX motherboard is the number of PCIe 4.0 expansion slots. Most mini-ITX motherboards have only 1 full-size PCIe x16 slot which may have PCIe Gen 3 or PCIe 4.0 capability depending on the chipset.

Some motherboards might include one or two 1x PCIe 4.0 slots as well, but it is rare to see that feature. Therefore, if you want to install lots of expansion cards and graphics card options you might want to check the number of expansion slots on your PC hardware beforehand.

FAQs
