Socket AM4 DDR4 platform

The GIGABYTE B550M AORUS PRO AX is a Micro ATX motherboard built around the AMD B550 chipset for Socket AM4 processors. It supports Ryzen CPUs with integrated Radeon graphics and provides four DDR4 DIMM slots with a maximum memory capacity of 128GB. The board measures 24.4 by 24.4 centimetres and includes a single PCI-E x16 slot that runs at PCIe 4.0 with third-generation Ryzen CPUs.

Verify CPU generation and cooler clearance

Confirm that your processor is a Socket AM4 model; third-generation Ryzen CPUs enable PCIe 4.0 on the primary x16 slot while earlier Ryzen models with Radeon graphics operate at PCIe 3.0. Check that your CPU cooler fits within the Micro ATX layout and that your power supply provides the necessary 24-pin and 8-pin EPS connectors. The rear I/O panel is included in the package.

Connect storage and peripherals

Two M.2 interfaces and four SATA III ports give flexibility for SSDs and hard drives, and one SATA cable is supplied. The integrated Realtek 2.5GbE LAN controller handles wired networking at 2.5 Gbit, 1 Gbit or 100 Mbit speeds. Rear USB connectivity includes three USB 3.2 Gen 1 ports, one USB 3.2 Gen 2 Type-A port and three USB 2.0 ports, while the Realtek ALC1200 audio codec supports up to 7.1-channel output.
