The MSI PRO B550M-B Micro-ATX motherboard supports AMD AM4 processors. Using the AMD B550 chipset, it is compatible with AMD Ryzen 5000, 4000 G-Series, and 3000 series desktop processors. Its compact form factor is suitable for home or office cases with limited space. System memory uses two DDR4 DIMM slots configured for dual-channel operation, supporting a maximum of 64 GB of unbuffered, non-ECC RAM. With compatible modules and overclocking profiles, the memory subsystem supports speeds up to 4600 MHz.
The board features two M.2 slots for NVMe SSDs in 2280, 2260, and 2242 sizes, and four SATA III ports for additional drives. A single PCIe Gen 4 x16 slot accommodates a graphics card. Integrated graphics are available via an HDMI 2.1 port and a DisplayPort 1.2 connector on the rear panel. Wired networking is handled by a Gigabit Ethernet port, though this model lacks onboard Wi-Fi and Bluetooth.
