ASRock Fatal1ty B450 Gaming-ITX/ac Review: Small Wonder

Editor's Choice

How We Test

A lack of Mini-ITX samples for socket AM4 forced us to re-test an earlier ASRock model, the X370 Gaming-ITX/ac, as a direct comparison to the cheaper and more modern B450 Gaming-ITX/ac. Larger ATX models based on the even higher end X470 chipset, the Biostar Racing X470GT8 and Gigabyte X470 Aorus Gaming 7 WiFi, fill out the rest of our comparison roster. We hope that including those top boards will help to prove the worth of today's lower-cost focus.

Graphics DriverGeForce 399.24

The same platform that cools the intense heat of our X299 motherboards works equally well with AMD’s AM4 processors, as proven in the overclocking evaluation on the next page.

    I've been eyeing this board for months now; it looks like a real winner. If I build another AM4 system (hey, I DO have a 1600X on a shelf right now...), this one is on the Short List.

    Looks like a cheap but still good ITX option. Thanks for review.

    A real Intel I211 Gigabit Ethernet controller. Very NICE! Much better than Realtek

    Historically, the only expansion cards I have used are video cards, modems, and wireless NICs. Ok, I can add a video card to this board. I don't need a standard modem, and my Brother MFC all-in-one can fax (yes, I've done it quite a few times); and this board has wireless built-in. It's marginally low on SATA ports, but the M.2 takes care of that, so I can have: Data drive, Backup drive, optical drive, and external SATA dock, in addition to the M.2 boot drive.
    So, it checks all the boxes. Well, all except current need...

    great board, but for the past 3 weeks the Bluetooth started to disconnect every second so i had to disable it in device manger.. ill get to fix it when I have time..
