BIOSTAR today rolled out the B550M-Silver, a Socket AM4 motherboard in the Micro-ATX form-factor, based on the AMD B550 chipset. The board comes with out-of-the-box support for the latest Ryzen 5000 "Vermeer" processors, in addition to Ryzen 4000 "Renoir" and Ryzen 3000 "Matisse." It draws power from a combination of 24-pin ATX and 8-pin EPS power connectors, conditioning it for the CPU with a 10-phase VRM that comes with heatsinks across all CPU VRM phases. Expansions slots on the BIOSTAR B550M-Silver include one PCI-Express 4.0 x16, a PCI-Express x16 (electrical gen 3.0 x4 and wired to the B550 chipset), and a PCIe 3.0 x1.

Storage connectivity includes six SATA 6 Gbps ports, and two M.2-2280 slots, from which one has PCI-Express 4.0 x4 wiring to the CPU socket; and the other PCI-Express 3.0 x4, wired to the B550 chipset. USB connectivity includes two 10 Gbps USB 3.2 ports on the rear panel (from which one is type-C), four 5 Gbps USB 3.2 ports (from which two are via headers), and six USB 2.0 ports (two on the rear panel, four via headers). Networking includes a 2.5 GbE wired interface handled by a Realtek 8125B controller, and preparation for a WLAN module (an M.2 E-key slot and mounts for antennas are provided), although one isn't included with the board. The onboard 6-channel HD audio solution is handled by a Realtek ALC1150 CODEC. The company didn't reveal pricing.
