Socket AM4 Platform

The GIGABYTE B550M AORUS ELITE is a Micro ATX motherboard built around the AMD B550 chipset. It accepts Ryzen 3000, 4000, 4000G, 5000 and 5000G series processors in the AM4 socket. The board targets builders who want a compact foundation for gaming or productivity systems.

Expansion Layout

Four 288-pin DDR4 slots support up to 128 GB of memory running at 3200 MT/s. Two PCI Express 4.0 x16 slots and one PCI Express x1 slot provide room for a graphics card and add-in boards. Storage connectivity includes four SATA 6 Gb/s ports and two M.2 sockets. Rear I/O supplies six USB 3.1 ports, HDMI, 1 Gbps LAN and PS/2.

Sustained Operation

The 12+2 phase digital power design with DrMOS delivers stable current to the CPU during extended workloads. An enlarged heatsink on the VRM area and a dedicated M.2 thermal guard help dissipate heat without relying on high fan speeds. Realtek ALC887 7.1-channel audio and GbE LAN maintain consistent throughput during long sessions.
