The ASUS PRIME B550M-A is a Micro-ATX motherboard designed for AMD Ryzen 5000, 4000 G-Series, and 3000 Series processors. Built around the AMD B550 chipset, it provides a compact foundation for a reliable PC build, measuring 24.4 x 24.4 cm to fit easily into smaller chassis. You can install up to 128 GB of DDR4 memory across four DIMM slots, with overclocking support reaching frequencies up to 4866 MHz for those needing faster data handling. For storage and expansion, the board features a PCIe 4.0 x16 slot for modern graphics cards and two M.2 slots, the primary one of which supports PCIe 4.0 x4 for high-speed NVMe drives. It includes four SATA 6Gb/s ports with RAID 0, 1, and 10 options, ensuring flexible drive configurations. Connectivity is handled by a Realtek Gigabit Ethernet controller and a 7.1-channel high-definition audio codec, while the rear panel offers a mix of USB 3.2 Gen 2 and Gen 1 ports for quick peripheral transfers. Visual flexibility is a highlight, as the board includes HDMI 2.1 for 4K output at 60Hz, alongside D-Sub and DVI-D ports for older monitors. Internal headers for RGB LEDs and a COM port allow for personalization and legacy hardware support. This motherboard suits users building a balanced home or office system who value a blend of current PCIe 4.0 speeds and broad compatibility with various display standards.
