ASRock B850M Pro-A WiFi

The B850M Pro-A WiFi is ASRock's budget micro-ATX entry on the B850 chipset, aimed at builders who want a current-generation AM5 board with a PCIe 5.0 GPU slot and Gen5 M.2 support without paying for a full ATX layout.

Power delivery uses an 8+2+1 phase design with Dr.MOS power stages covering VCore, SOC, and miscellaneous rails, sufficient for Ryzen 9000 non-X3D chips at stock clocks but not intended for aggressive overclocking. Four DDR5 DIMM slots support up to 256GB total capacity, with overclocking rated up to 8000+ MT/s on supported Ryzen 9000/8000/7000 processors. Expansion includes a PCIe 5.0 x16 slot from the CPU and a PCIe 4.0 x4 slot from the chipset. Storage covers three M.2 sockets: one "Blazing M.2" PCIe 5.0 x4 slot and two "Hyper M.2" PCIe 4.0 x4 slots. A 2.5 Gigabit LAN controller handles wired networking, paired with an 802.11axe Wi-Fi 6E module. Audio uses a Realtek ALC897 7.1-channel codec. Compared to the Gigabyte B850M AORUS STEALTH ICE in this catalog, the B850M Pro-A WiFi is priced lower and includes a PCIe 5.0 M.2 slot, making it a strong budget alternative for builders who don't need the Gigabyte board's extra styling options.
