ASRock B550M-ITX/AC Supports 3rd Gen AMD AM4 Ryzen™ / Future AMD Ryzen™ Processors motherboard Mini ITX

I’ve bought this motherboard more than any other motherboard in my life, and I’ve bought many. It’s all you need for AM4 ITX/SFF builds. Easy to use. Runs stable with XMP/EXPO memory overclock. Came with the latest BIOS installed. I used a Ryzen 5600X and RTX 5070 with this motherboard. Ethernet, Wifi, and Bluetooth work right out of the box.

Before you start building I'd recommend swapping out wifi card with a ax211 or better. I put a ryzen 5 3600 in it, dual ddr4 16gb 3200mhz ram kit in it (32gb total). 500w psu, and a old 3060ti I had laying around in SFF case with handle. CPU and motherboard temp are close in temperature. So if gaming and CPU is around 63c motherboard would be displaying a temp of something like 58c. I'm only mentioning this cause people are saying the thermal plate for motherboard is too small. If you put something crazy on this board like a 4080 with a 5950x 16 core CPU, and 4000+mhz ddr4 ram. I can't say for sure, but I have no doubt that plate would be a problem. Keep in mind this is a budget board, and you shouldn't expect miracles. That being said me and my stepson played WWE 2k24 for hooooouuurrss multiple times on it so far. No issue at all. First time buying a ASRock board as well and the bios and ASRock apps seem kinda crude and dated compared to MSI or ROG, but definitely has everything you need to modify bios, fan speed, rgb etc. I kinda like it. I'm real happy with purchase.

It's solid, convenient, and easy to use. The included instruction sheet could be a little more clear but it's usable. I quite like Asrock boards. They always do a great job for me.

Purchased this mobo from amazon. After a year I was getting major issues with the pc crashing own once in a while. Motherboard still under warranty and Asrock confirmed fault/confirmed warranty but after more than 4 weeks of back and forth neither Amazon nor Asrock are willing to replace, refund or repair the board! Had to buy a motherboard twice as expensive to fix the issue bscause of this horrible customer service from both Asrock and Amazon.

Used this board for a mini ITX build. I think the board is well built, includes the most important headers (no USB C header for case sadly) and has a good BIOS menu with plenty of settings to use XMP and other options. My Ryzen 5 5600x worked out of box and did not require a BIOS update. This board was 100% functional for the first 3 months I had it, then I started to experience blue screens that I could not solve. Finally, after a couple days and a few hours, I figured out that it was a BIOS issue and when I updated the BIOS and cleaned my PC, it worked fine again. I like the board, I think it has exceptional value in a budget board. I hope it continues to work into the future.
