    A solid option if Taichi is out of your price range

    Be sure to update the BIOS first. I could not get Win 10 to install until I downloaded and installed the latest version. This was a Ryzen 5 5600x build. I wish this motherboard had two things...an external CMOS reset switch on the back I/O and an on-board hard drive activity light. But for what you get, I can't complain about the price. I got it to POST on the first try. Everything is running as it should and the aesthetics are attractive. I like how the board is laid out with regard to fan and aRGB headers giving you plenty of options in terms of cable routing. Also, the latest version of Asrock Polychrome sync is better than AuraSync IMO. If you can afford a Taichi, get that instead. But for under 180 dollars this is a competitive option.

    Used motherboard like new

    Product performs like new. Pervious owner didn't not clear TPM setting before the sell meaning I had to leave it disable but otherwise works perfect for my DIY NAS use.
