Review: great affordable small form factor motherboard - *B550 works with PBO on x3d processors *ARGB connectors *wifi *cheap *ASRock has really earned my respect lately great build quality, I build a SFF in the Fractal Ridge with a 5700X3d, 32gb ddr4, RX6750XT. Overall motherboard handled it all very well. did exactly what I needed it to do. It did require a bios update to get PBO on the X3d but that is normal, it was released after the product was made.
Review: Hasn't let me down great for modest gaming. - 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.

### ⭐⭐⭐⭐⭐ Great AM4 B550 Mobo
*by N***. on January 10, 2026*

Great cheap mini itx for for am4. Only problem with this is am4 is getting old but that's nothing to do with the product itself. Its easy to build on its small with a basic layout. Can fit inside of most mini itx cases you want and my bios came preupdated.
