Socket AM4 motherboard for Ryzen builds

The MSI MPG B550 GAMING EDGE WIFI is an ATX board built on the AMD B550 chipset for Socket AM4 processors. It supports 3rd Gen AMD Ryzen CPUs and future Ryzen processors with a BIOS update. The board targets enthusiasts who want high memory speeds and 2.5Gbps networking in a standard form factor.

Standard ATX install with Wi-Fi antenna

Installation follows normal ATX mounting in any compatible case using the supplied I/O back panel. A CMOS battery and one SATA cable are included in the box. The Wi-Fi antenna must be attached to the rear panel if wireless is required. Builders should verify CPU cooler clearance against their chosen case before fitting the board.

128GB DDR4 maximum capacity

Four DIMM slots accept dual-channel DDR4 up to 128GB total across a wide frequency range from 1866 to 4866+ MHz. This ceiling determines whether the board suits high-capacity workloads or memory-intensive applications. Expansion includes one PCIe 4.0 x16 slot, one PCIe 3.0 x16 slot at x4 speed, two PCIe 3.0 x1 slots, six SATA III ports and two M.2 interfaces.
