GALAX B550M DDR4 AMD Motherboard

The GALAX B550M DDR4 AMD Motherboard is a Micro-ATX form-factor board built on the AMD B550 chipset with an AM4 socket, offering compatibility with AMD Ryzen 5000 Series, 4000 G-Series, and 3000 Series desktop processors. Whether you are assembling a compact gaming rig or a productivity workstation, this board provides a solid combination of modern connectivity, storage flexibility, and display output options at a competitive price point. At the heart of the platform is a PCIe 4.0 x16 primary expansion slot — available when paired with Ryzen 3000 series or newer CPUs — delivering twice the bandwidth of PCIe 3.0 for high-speed discrete graphics cards or NVMe storage adapters. A secondary PCIe 3.0 x1 slot covers additional expansion needs such as capture cards or sound cards. Storage options are versatile: four SATA 6 Gb/s ports accommodate traditional hard drives and SSDs, while an M.2 slot supports PCIe 32 Gbps devices as well as SATA III-based M.2 drives, giving builders the flexibility to choose their preferred storage tier. Display connectivity spans VGA, DVI, and HDMI outputs for use with integrated Ryzen G-Series graphics. System memory runs in dual-channel configuration across two DIMM slots, supporting up to 32 GB of DDR4 at speeds from 2133 MHz up to 3000 MHz (OC). USB connectivity is comprehensive: 2 x USB 3.2 Gen2 (10 Gbps) ports for fast peripherals, 4 x USB 3.2 Gen1 ports, and 6 x USB 2.0 ports for legacy devices. Onboard networking is handled by the Realtek RTL8111H Gigabit LAN controller. Audio is delivered through a Realtek ALC662 VD 6-channel HD Audio CODEC with an illuminated audio trace path featuring white LED accents. The board includes an RGB header for connecting compatible RGB fans and LED strips into a unified lighting system, plus ESD protection circuitry to guard sensitive components against electrostatic discharge. UEFI BIOS support simplifies system tuning and overclocking setup.
