How to Choose the Best Mini ITX Motherboard

Here are three key tips to ensure you select the optimal mini ITX motheboard for your SFF PC build:

Carefully Match the Socket and Chipset to Your CPU

As mini ITX boards allow limited upgrading, it’s vital to choose a socket and chipset designed specifically to maximize your chosen CPU.

Those using 13th Gen Raptor Lake chips will want an LGA 1700 Z790 motherboard primed for overclocking with robust power phases.

For AMD Ryzen 7000 owners, an X670E/X670 or B650/B650E motherboard ensures you fully harness the overclocked DDR5 RAM, PCIe 5.0 lanes and other advantages of Zen 4 architecture chips.

Check Dimensions to Ensure Case Compatibility

While the mini ITX form factor standard sets motherboards at just 6.7 x 6.7 inches, you’ll still want to cross reference measurements with your PC case.

Some chassis made for small motherboards have very tight clearances. So double check specifications listed to guarantee everything fits.

Also keep expansion slots, RAM clearance and connector positioning in mind if employing components with larger heatsinks or custom liquid cooling.

Add Components Offering Similar Speeds

A common mistake is mismatching ultra fast DDR5 RAM, PCIe 5.0 SSDs and high end GPUs with more affordable motherboard tiers.

Balancing speeds across components prevents leaving performance on the table. An elite Z790 DDR5 board won’t benefit mid-range DDR4 RAM. And a budget B650E board can’t fully exploit an RTX 4090’s potential.

So match elements like CPU tier, RAM generation and PCIe version across parts for a harmonious, high performance build.


While limited to compact dimensions, today’s best mini ITX motherboards deliver virtually full size power. They harness cutting edge sockets, chipsets, PCIe and RAM support to create true performance powerhouses.

We hope this guide to ranking the top models aided your search for a flawless foundational component. Just be sure to verify comprehensive compatibility, anticipated use case and budget when deciding on the perfect option for your small form factor PC project!
