ASUS PRIME B550M-A WIFI II mATX Motherboard | AM4 | 4x DDR4 Slots | Wi-Fi 6
Description
The ASUS PRIME B550M-A WIFI II is a micro ATX motherboard built around the AMD B550 chipset, targeting mainstream users who want modern features in a compact build. Supporting both Ryzen 3000 and 5000 series processors through the AM4 socket, this board brings PCIe 4.0 connectivity and Wi-Fi 6 to smaller PC builds without sacrificing essential features. The micro ATX form factor makes it suitable for mid-tower cases while offering more expansion room than Mini-ITX alternatives.
Memory support extends to 128GB across four DDR4 DIMM slots, with speeds reaching up to 4866MHz through overclocking profiles. The single PCIe 4.0 x16 slot provides full bandwidth for modern graphics cards, while dual M.2 slots accommodate high-speed NVMe storage. Two additional PCIe 3.0 x1 slots offer room for expansion cards. Connectivity includes Wi-Fi 6 wireless, Gigabit Ethernet, and multiple display outputs including HDMI, DVI-D, and D-Sub for integrated graphics setups.
The board includes practical extras like Aura Sync RGB lighting support through a dedicated header, ECC memory compatibility for those needing error correction, and USB 3.2 Gen 2 ports for fast peripheral connections. ASUS includes the standard package of I/O shield, SATA cables, M.2 mounting hardware, and user documentation. The B550 chipset ensures compatibility with current AMD processors while providing upgrade headroom for future Ryzen releases on the AM4 platform.
