The ASRock B850M Pro-A is a motherboard built on the AMD B850 chipset for the AM5 socket, providing compatibility with Ryzen 7000, 8000, and 9000 Series processors. Its Micro ATX form factor makes it suitable for compact to mid-size PC builds. The board features four DDR5 DIMM slots that support dual-channel memory configurations up to 256 GB, with maximum clock speeds of 8000 MHz. Power is delivered through standard 24-pin ATX and 8-pin EPS connectors, ensuring stable operation for all connected components.
For storage and expansion, this model includes three M.2 slots, one of which utilizes the PCIe 5.0 interface for current-generation high-speed solid-state drives. It also offers four SATA III ports with RAID 0, 1, and 10 support for additional storage configurations. The primary expansion slot is a PCIe 5.0 x16 interface intended for a graphics card. Connectivity is handled by a 2.5GbE LAN port for high-speed wired networking, along with integrated Wi-Fi and Bluetooth for wireless connections. Onboard audio is processed by the Realtek ALC897 audio chip.
