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

*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.

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 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.

no issues with the hardware i'm running. cpu power is in a weird spot. good price for an itx board, tho it is very old at this point. nice to see that they're still in stock.

Trash Bluetooth. I can't even get into the BIOS at least 50% of the time unless BT is disabled on the board. Tried multiple revisions.

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 M/B as this is the last available upgrade choice which can utilize my DDR4 RAMs. (As of 2025 October) Works perfectly well with 5700X3D processor - PBO & Curve Optimizer supported. BIOS version was v3.40 Only quick guide was included in the box, but builders interested in ITX board/SFF PCs will not really need more than this.

Not sure how to rate this, because part of the rating is for the motherboard, and part is for Amazon. I gave 1 star to Amazon and 4 stars to the motherboard. That's an average score of 2.5, which I rounded up to 3. The Amazon Part I got an obviously open-box item instead of the new one I paid for. I won't buy any more computer components from Amazon because of that. That's no way to treat customers. Pros None that I can see. Cons Bad Amazon! No, no, no! The Motherboard Part Booted on the first try, and it seems to be functioning well. I had one blue screen crash, but I had several odd web applications open, and I think that one of them (or the combination thereof) caused the error. Other than that, I've had no problems. I've had good luck with ASRock motherboards (so far), and I tend to stick with a brand that works for me. Pros It's a good board for a small computer case. Hardware Monitor reports what looks like correct temperatures, which wasn't happening with the motherboard I replaced. Cons None that I can see.
