Compact micro-ATX motherboard with 4 DDR4 memory slots, integrated PCI-E 4.0 data bus and built-in Wi-Fi receiver. Equipped with an AMD AM4 processor socket, it runs on the middle-class B550 system logic. Compatible with most Ryzen processors released between 2017 and 2022, including the Pinnacle Ridge, Summit Ridge, Raven Ridge, Matisse, Picasso, Vermeer, Cezanne, and Renoir families.

It is a representative of the universal Asus Prime series, which in most cases is designed for office assemblies, multimedia systems and inexpensive workstations. Despite its compact size, the layout of the device slots does not limit the owner, making it possible to assemble a productive and modern PC with a large amount of memory and a powerful video card on its basis. The slot layout includes 4 slots for DDR4-4866 memory with support for XMP profiles (maximum 128 GB), two M.2 slots for miniature M.2 SSDs, and four classic SATA3 connectors for standard HDDs and SSDs.

Additional bonuses in the Asus PRIME B550M-A WIFI II sleeve are additional cooling of the M.2 zone, support for the USB C 3.2 gen2 interface, a high-quality network controller and connectors for installing LED strips. All things considered, the board is best suited for building an office PC, a work PC for authoring content, or a gaming system sharpened for games in 1080p resolution.
