Best AM4 Mini ITX Motherboard

Socket AM4 Mini ITX Motherboard B350 & X370 Chipset for AMD Ryzen 7

After the initial success of AMD’s Ryzen CPU’s, motherboard manufacturers have started releasing at least one socket AM4 Mini ITX Motherboard. The SFF (Small Form Factor) enthusiast market is arguably a niche market to cater to. However, the market demands it, and it looks like the manufacturers obliged.

This year, AMD launched their AMD Ryzen CPU family, which earned tremendous respect from customers that consist of both content creators and gamers. AMD released them as a response to its arch rival, Intel’s Skylake series CPU family. Since the day of its release, Ryzen platform is going more and more popular among gamers. It’s arguably after a long time that gamers preferred AMD over Intel processors.

Coming to the topic, today we are going to discuss the best mini ITX motherboard (s) based on AMD’s B350 and X370 chipsets. There are multiple chipsets/platforms out there to use with AMD Ryzen processors. However, they are not identical to easy other. In fact, they are entirely different.

For example, B350 is suitable for mainstream builds, more based on on-paper specs. On the other hand, the X370 is designed for PC enthusiasts as it is highly overclockable. It is perfect for multi-GPU (Both Crossfire & Nvidia’s SLI) setups. Before we discuss the motherboards based on these chipsets, here is a quick comparison between them:
