The MSI MPG B550 Gaming Plus is a full-size ATX motherboard for AMD's AM4 socket, built around the B550 chipset. It pairs PCIe 4.0 support for a current graphics card and one M.2 slot with a 1G LAN port, USB 3.2, HDMI and DisplayPort outputs, and S/PDIF audio. A front LED strip and RGB headers give it more visual customization than plain B550 boards, while extended PWM heatsinks and an M.2 Shield Frozr cover handle thermals. It suits builders who want a roomy ATX board with PCIe 4.0 and lighting control without stepping up to X570.
