GIGABYTE B550M GAMING AMD motherboard

Micro ATX B550 board for Ryzen builders

This micro ATX motherboard uses the AMD B550 chipset and an AM4 socket to support Ryzen and Athlon processors. Two DDR4 DIMM slots accept up to 64 GB of memory running at 3200. A single PCI Express 4.0 x16 slot and two PCI Express x1 slots handle graphics and add-in cards, while four SATA 6 Gb/s ports and one M.2 connector provide storage options.

5+3 phase digital VRM with low RDS(on) MOSFETs

The power delivery uses a 5+3 phase pure digital PWM design with low RDS(on) MOSFETs to supply clean current to the CPU. Realtek ALC887 audio delivers 7.1 channel output through the rear panel. Networking is handled by a Realtek 8118 Gigabit LAN controller with automatic bandwidth allocation and enhanced ESD protection. Rear I/O includes HDMI, PS/2, four USB 2.0 ports and six USB 3.1 Gen 1 Type-A ports.

Check CPU cooler clearance

The board measures 244 x 205 mm, so verify that your chassis supports micro ATX dimensions and that the CPU cooler fits around the VRM heatsinks. Confirm that your M.2 drive matches the connector keying and that you have enough SATA cables for the four 6 Gb/s ports. Ensure the power supply provides the required ATX 24-pin and 8-pin EPS connectors for the digital VRM.
