Gigabyte B550M AORUS ELITE AX (rev. 1.4) motherboard AM4, micro-ATX, DDR4, Wi-Fi 6E

The Gigabyte B550M AORUS ELITE AX (rev. 1.4) is a micro-ATX motherboard for the AMD AM4 socket on the B550 chipset. Four DDR4 slots, a PCIe 4.0 graphics slot and M.2 slot, and built-in Wi-Fi 6E make it a solid base for a Ryzen 5000 gaming PC in a smaller case.

  • Socket and chipset: AMD AM4, B550; Ryzen 3000, 4000 and 5000 series
  • Form factor: micro-ATX, 244 × 244 mm
  • Memory: 4 × DDR4 DIMM, dual channel, up to 128 GB, up to 4733 MHz
  • Storage: M.2 PCIe 4.0 (up to 22110) + M.2 PCIe 3.0 (2280), 4 × SATA III
  • Expansion slots: PCIe 4.0 x16, PCIe 3.0 x16, PCIe 3.0 x1
  • Network and outputs: Wi-Fi 6E, Bluetooth, 1 GbE (Realtek RTL8111H), HDMI 2.1, DVI-D

Description

PCIe 4.0 for the graphics card and a fast SSD

The first PCIe x16 slot and the first M.2 slot run at PCIe 4.0, so newer graphics cards and NVMe SSDs get their full bandwidth. Power is handled by a 5+3 phase digital VRM. Q-Flash Plus lets you update the BIOS without a processor, memory or graphics card installed. RGB FUSION 2.0 controls addressable and standard RGB strips, and Smart Fan 5 runs the fans with a FAN STOP mode.

Who this motherboard is for

Gamers building or upgrading an AM4 PC who want four memory slots, Wi-Fi 6E and two M.2 slots on one micro-ATX board. Support for Ryzen 3000, 4000 and 5000 series means an existing processor can be reused, and up to 128 GB of DDR4 leaves headroom for the future.
