The MSI PRO B550M-P GEN3 keeps a PS/2 port and Gigabit LAN for budget builders

MSI’s PRO B550M-P GEN3 is the only board in this batch with a PS/2 combo port and a Gigabit Ethernet jack — everything else runs 2.5GbE. That makes sense for a budget micro-ATX board. You still get a USB-C at 10Gbps and four USB 3.2 Gen 1 ports, so daily-driving peripherals won’t be a problem. HDMI 2.1 and DisplayPort 1.2 handle the video outs.
