With high performance desktop ITX options appearing more frequently with each new generation of chipset, ASRock released a pairing of AM4 offerings to satisfy small form factor enthusiasts. Although the ASRock X370 Gaming-ITX/ac is one of the most expensive AMD Ryzen compatible motherboards on the market, it tries to offer more than the standard mini-sized motherboard.

The X370 Gaming-ITX/ac is marketed towards gamers with the board being associated Fatal1ty branding; ASRock has a branding deal and partnership with the successful early-2000s gamer, Johnathan ‘Fatal1ty’ Wendel. The idea is that being gaming focused - there will be gaming features. This starts with a typical gaming color scheme: an all-black PCB with a pairing of metallic red power delivery chipset heatsinks.
