Overview

A Micro-ATX motherboard built on the AMD B550 chipset for Socket AM4 processors. It fits compact builds while delivering PCIe 4.0 graphics support and fast networking.

Compact Design and Power Delivery

The Micro-ATX form factor uses a black PCB with gray and silver accents. A 5+3 phase VRM is fed by a single 8-pin CPU power connector to handle multi-core Ryzen processors.

Memory and Storage Options

Four DDR4 DIMM slots accept up to 128 GB of memory with overclocked speeds reaching 4733 MHz. Storage includes one PCIe 4.0 x4 M.2 slot, one PCIe 3.0 x2 M.2 slot, and four SATA 6 Gbps ports.

Expansion Slots and Rear Connectivity

A full-bandwidth PCIe 4.0 x16 slot sits alongside a PCIe 3.0 x16 slot wired at x4 and a PCIe 3.0 x1 slot. Rear I/O provides DisplayPort, HDMI, DVI-D, four USB 3.0 Type-A ports, four USB 2.0 ports, 2.5 GbE LAN, and Wi-Fi with Bluetooth antennas.

Internal Headers and Lighting Control

Three 4-pin fan and pump headers provide cooling flexibility. Two 3-pin 5 V digital RGB headers and three 4-pin 12 V RGB headers allow addressable and standard LED strip control through Gigabyte software.
