    Solid motherboard. Good layout with great I/O. No problems building with it. Has everything I need.

    Flashed to new BIOS for Ryzen 2 with Ryzen 5 2600; worked perfectly and had no issues with Ryzen 3600.

    The ASRock B450 Gaming-ITX/AC is a great motherboard for the price. I got it on sale for $109.99 at Microcenter. The board was excellent to work with and having 2 case fan headers was amazing especially for a mini itx motherboard.

    A Mini-ITX Mobo that has most all the features I was looking for ( including optical audio out) at a great price. The wire connectors are in generally thoughtful positions, and it has the all-important third fan header, somewhat of a rarity on ITX boards. BIOS is perfectly adequate, supports 3200 RAM, and have not ran into any issues in the 6 months of ownership thus far.

    First board had issues, have yet to send the first board back, if i can receive a new one with no issues this will go up to 4 stars. Second one worked fine.

    Good value board with a lot of features including wifi packed into a small package.

    VRMs aren't so impressive (3-Phase) but the inclusion of Type-C Gen2 and optical audio port sold me.

    This is the cheapest ITX B450 board on my local market, but it is quite good. Solid internal connectivity and excellent rear I/O.

    Love the features and price. USB-C, optical audio out, and Zen2 recognized on first boot. Note that there is only one M.2 drive.

    I think this is the perfect AM4 ITX board if you are looking for something basic and something that works really well. I have had zero issues with this motherboard. The only problem I have was something I did because I broke the USB 3.0 port on it so I cant actually use the front IO on my case. :( Not the motherboards fault though.

    from completed build O.C. 2200G

    The Asrock B450 Fatal1ty Motherboard offers HDMI/Displayport video outputs, Dualband WiFi, and Bluetooth which are all useful features for a portable system limited to the video outputs implemented on the Motherboard. Overclocking in the BIOS is straightforward, and the build quality and layout are both great. Includes a nice I/O shield as well.

    Good selection of ports. Wifi is a little weak.
