Buying Guide for the Best Mini ITX Motherboard

The motherboard can be considered the prime component of any computer system. Without a good motherboard, other components will fail to operate precisely. The CPU primarily benefits from a high-end motherboard.

A good motherboard can and will increase or decrease the overall performance of your desktop. Therefore, it’s in your best interest that you should study motherboards before buying one.

You should consider multiple criteria and features for your desired motherboard. Such as mini ITX form factor PCs are easier to carry around. Every motherboard has both strong and weak points. Make sure you choose the one that best suits your needs.

Here are some of our top considerations while making this curated list of the best mini ITX motherboards.

Form Factor

While buying a motherboard, it’s crucial to know about its Form Factor. Although they do not impact your phantom gaming performance, it is necessary to have the correct form factor to fit your motherboard into the casing.

Motherboards come in usually in three types of form factors. ATX, Micro-ATX, and mini ITX form factor. You’ll have to keep in mind that the Standard ATX boards are bigger. On the other hand, the mini-ITX motherboards are smaller boards for more compact builds.

Chipset

The chipset of the motherboard determines your processor type. For instance, the latest generation Intel processors require Z490 chipsets, while most AMD processors can work with various chipsets like B450, B550, and X570.

So, you need to find the motherboard with the right chipset compatible with your CPU.

Socket

Another thing that needs to be compatible with your CPU is the socket type of the motherboard. The latest-gen AMD processors require an AM4 socket. On the other hand, Intel processors use LGA1200 sockets.

It is vital to know the socket type of your motherboard. Otherwise, your CPU will not be installed into the motherboard.

Memory Slots

Memory slots are the slots where the RAM modules are installed. Usually, all ATX motherboards have 4 DIMM slots, but mini ITX motherboards have 2 DIMM slots to make them more compact.

Motherboards are also limited to their maximum memory capacity. Meaning, not every motherboard can support 64GB or 128GB RAM. So, make sure your motherboard can handle the total amount of RAM you want to use.

PCI-E Slots and Expansion Slots

Necessary components like Graphics cards, network cards, and sound cards go into the PCI-E slots. Depending on the form factor, the motherboard will have a fixed number of PCI-E slots. ATX motherboards might have 5-6 PCI-E slots, while mini ITX motherboards usually offer 2-3 PCI-E slots.

M.2 Slots and NVME slots

Days of SATA HDDs or SSDs are over. In this era, you need super-fast M.2 or better NVME SSDs installed on your rig.

Most modern motherboards support multiple M.2 and NVME slots these days. Choose the motherboard that offers adequate storage options according to your needs.

Connectivity

A motherboard connects all the different parts, devices, and components that a system needs to use. Including input, output devices, internal components are connected via the motherboard.

Make sure your mini ITX motherboard features include all USB ports like USB 3.0 ports, USB Type C ports, dual HDMI, Display ports, Ethernet ports, etc. These ports are necessary for day-to-day life.

Buying extension slots or cables is an unnecessary hassle if your motherboard can offer these ports itself.

BIOS

It is the software that maintains and manages your whole system. BIOS update can increase your system performance and stability by a mile. Manufacturers these days offer regular BIOS updates to improve the motherboard’s optimization and functionality.

It also offers manual overclocking and headroom for system performance increment via the BIOS menu. You can tweak your desired settings if your motherboard has a high-end BIOS UI.

Aesthetics and Thermal Solution

A monstrous rig needs proper aesthetics and thermal solution to work. A motherboard’s design matters a lot in the overall looks of the system. Also, a high-end system can get heated a lot, and the motherboard needs to handle the heating issues.

High-end mini ITX motherboards have multiple heatsinks to transfer the heat efficiently. Some mini ITX motherboards also offer RGB lighting that can undoubtedly add up to your build’s aesthetics.
