  • Excellent gamin board and low price!
Style: B550M PRO4
ASRock is a great brand. I already have the x399 phantom gaming 6 for my Threadripper system which is running my personal Ai. This board is no slouch either! It’s too gaming extraordinaire and happy with the performance

  • Its great so far! (just don't purchase on sale) 😬
Style: B550M PRO4
Five stars! (so far!) It is a very sturdy, high quality, and beatiful looking motherboard especially for the price! I have a feeling that some people are getting returned and faulty motherboards because they bought it on sale so just stay cautious about the super good flash deals because they might just be sending you a returned one to save money but other than that it is 5 stars! ... show more

  • standard USB 3.1 port, USB-C 3.1 port, dual USB 3.0 headers and a massive heatsink
Style: B550M PRO4
Best micro am4 motherboard out there IMHO... Bought as a gift and will buy one for myself in the future... Most don't have dual USB 3.0 headers but no USB 3.1 header... wish it had one but it has dual USB 3.1 ports on the back which is a must... one usb-c and one standard usb a... both usb 3.1... Has massive heatsinks as well for adequate cooling... Recommended ... show more

  • Good when it works.
Style: B550M PRO4
The media could not be loaded. Good looking board with expected performance. The issue with these boards is that a fault pops up after some usage where it will not post. The diagnostic lights just keep blinking. (See vid) No idea what the issue really is. If you search Google for this board several hundred examples of this failure will come up. Tech support is very quick, but with this board you will be RMAing it. December update: I have sent the RMA for a while now. No response from ASRock. When I send an email to literally every email I could find about ASRock I then get a response with an email address and phone number to call. That email is saying they are closed for the holidays and will return in 2023. This is the worst RMA experience I have ever had. Do not do business with ASRock . . . January update: I finally receive an email from the RMA manager saying the board is out of warranty. They were contacted in August about the issue, RMA request filled out before the end of the 1 year warranty. Because of ASRock not answering they claim it's now out of warranty. Do not buy ASRock unless you want to end up with dead products! ... show more

  • A solid little motherboard
Style: B550M PRO4
Honestly not a bad motherboard. I've used it on a daily office rig for 6 months now and it's been treating me well. Multi monitor with a 5600g cpu + 3060ti has been just fine. It looks good all things considering. It has two M.2 slots I'm a fan of. Plenty of USB 3.0+ ports. Has been forgiving to me as I swap, add, or upgrade other parts of the build. With a combination of other things, its handled office work and heavily modded GTA/Skyrim very well. Really no complaints. ... show more
