The Gigabyte B550M Gaming X WIFI6 is a Micro ATX motherboard with an AMD B550 chipset and an AM4 socket. It supports Ryzen 5000, 4000 G-Series and 3000 series processors. It has four DDR4 slots with dual channel memory and supports XMP modules.
Storage comes from two M.2 slots and four SATA 6Gb/s connectors. It has Wi-Fi 6, Bluetooth 5.3 and Gigabit Ethernet. HDMI and DisplayPort outputs are available for processors with integrated graphics.
The power design is a digital twin 5+3 phase VRM with a VRM thermal armor heatsink. The PCIe 4.0 x16 slot is built with 10X strength for graphics cards. The PCIe slots have a quick-release latch, and the Wi-Fi antennas attach through an EZ-Plug design.
