MSI PRO B650M-A WIFI Reviews

Do yourself a favor, don't buy this motherboard.

By Benjamin
Rated 1 out of 5
Date: 2023-01-20

Just buy yourself a Gigabyte, Asus or whatever motherboard instead but not an MSI. Here's why: 1. Can't get the ethernet port and WiFi to work 2. USB ports do weird things, my external sound card (focusrite 3rd gen) keeps cutting out 3. You might end up like me with a PC that doesn't boot anymore without having any idea why, impossible to access the BIOS. So here is a summary of my experience with this motherboard: problems and problems without any solutions and a lot of time wasted. (I just upgraded to Windows 11, I had the same problems with Windows 10 and this is not the first PC I built) This made me blacklist MSI.
