My first PC build went a little rocky but once I figured out my screw up I was good. This board is great easy configuration with the instructions.

    • ASUS again for me
Style: Prime B550M-A
I bought this to upgrade my hardware to W11. ASUS web support is great! It has compatibility information for CPU and Memory. I prefer the microATX dimensions, which this board is. The BIOS on this board did not need an upgrade for the AMD Ryzen 5-5700G CPU that I selected. BIOS also had a setting for dual monitors so I was able to use the onboard graphics and a video card. So, if you take your time, and read the specs, you will get a build. Be sure you windows license is RETAIL to permit easy activation with new mother board. ... show more

    • Good B550 board on a budget
Style: Prime B550M-A/CSM
Paired motherboard with a Ryzen 3 3100 and 2x8GB 3600 G.Skill RipJaws V Series. Worked with both out of box. Shipped with Bios version 0805. So would work with any 3000 series CPU but would need a Bios update for 5000 series. The Wraith Stealth cooler that came with the CPU and blocks the first memory socket. I only am using 2 slots at this time and recommended by manual for 2 was 2nd and 4th. So no problem for me but if I upgrade to all 4 slots will need to get a new color too. Over all great motherboard for the price. Very happy with this motherboard. ... show more

    • This board does NOT support BIOS flashback, despite the large ad on this Amazon page.
Style: Prime B550M-A/CSM
The motherboard (MB) itself works fine and was easy to work with for my build. My major issue is how it is being sold on Amazon and ASUS support. As of today, 06/14/2022, Amazon still shows a giant advertisement for the BIOS flashback feature. I didn't realize when I purchased the MB that despite the large ad promoting the feature, this MB does have it. My MB arrived with BIOS version 0805, and no surprise, would not run my 5600 chip. ASUS support was beyond useless, despite the ad for the BIOS flashback feature. This MB was being sold by ASUS, why not ship with an updated BIOS like other suppliers? It took some time and work, but AMD support came through with a loaner 3000 series chip I was able to use to update the BIOS and get my new chip working. AMD got a customer for life, but ASUS, nope, never buying from ASUS again. Come on Amazon, do the right thing and remove the BIOS flashback ad from this page! ... show more

    • Old bios as of 3/10/2022
Style: Prime B550M-A/CSM
BIOS still not upgraded to support Ryzen 5000 processors. This one is especially difficult to upgrade as it does not support 2nd gen processors, such as the ryzen 5 3400g. I had to find a non- "g" 3000 series processor and stand alone video card in order to upgrade the bios for my Ryzen 7 5700g based systems. To be fair, the product description states 3rd gen Ryzen, but other b550 motherboards I have used have upgraded bios. Besides that it seems a very good value MB. ... show more

    • Solid cheap board
Style: Prime B550M-A/CSM
The board itself is pretty good for what it costs, I have no problems powering a ryzen 5900x and radeon 6900xt. The one thing that I would change is the lack of fan headers and the lack of rear panel connectivity, but it is a "cheap" board and what you get is what you get.
