The GIGABYTE B550M AORUS ELITE AX is a Micro ATX motherboard based on the AMD B550 chipset with Socket AM4 support. It is designed for systems built around AMD Ryzen 5000 series processors and provides a balanced set of features for gaming, content creation and general PC use, including a 5+3 phase pure digital VRM, four DDR4 memory slots supporting up to 128 GB and PCIe 4.0 storage support.

Advantages

This motherboard delivers solid performance and modern connectivity: support for DDR4 memory at speeds up to 4733 MHz (OC), a PCIe 4.0 M.2 slot for high-speed NVMe SSDs, integrated Wi‑Fi 6E and Gigabit Ethernet, and USB 3.2 Gen 2 ports for fast peripheral connections. The 5+3 phase pure digital VRM offers stable power delivery for Ryzen CPUs in demanding workloads.

Suitable for

  • Gaming PCs using AMD Ryzen 5000 series processors
  • Compact Micro ATX builds requiring high-speed storage and networking
  • Content creation and productivity systems needing multiple memory slots and stable power delivery

Key specifications

  • Form factor: Micro ATX
  • Chipset: AMD B550
  • Processor socket: Socket AM4
  • Memory: 4 × DDR4 slots, up to 128 GB, up to 4733 MHz (OC)
  • VRM: 5+3 phase pure digital VRM
  • Expansion: 1 × PCIe 4.0 M.2 slot; PCIe x1 (Gen3) slots: 1
  • Networking: Wi‑Fi 6E, Gigabit Ethernet (GbE LAN)
  • USB: USB 3.2 Gen 2 ports

How to use

Install the GIGABYTE B550M AORUS ELITE AX into a compatible Micro ATX case and mount an AM4-compatible Ryzen CPU following the motherboard manual. Populate DDR4 memory modules into the four DIMM slots according to the recommended dual-channel configuration, connect storage devices including NVMe drives to the PCIe 4.0 M.2 slot, and attach power connectors from a suitable PSU.
