MSI PRO B650M-A WiFi

The PRO B650M-A WiFi is MSI's entry-level micro-ATX board for the AM5 platform, targeting budget Ryzen 9000/8000/7000 builds in compact cases where a full-size ATX board isn't needed.

MSI has not published an exact VRM phase count for this board; it is rated for Ryzen 9000 non-X3D chips at stock clocks, and reviewers note it is not intended for sustained heavy overclocking given its budget-tier thermal design. Four DDR5 DIMM slots support up to 256GB total capacity, with 1DPC 1R overclocking rated up to 7200+ MHz. Expansion includes two PCI-E x16 slots (supporting x16/x4, x8/x4, or x4/x4 depending on CPU) plus a PCI-E x1 slot. Storage covers two M.2 slots supporting PCIe 4.0 x4 with 2280/2260 form factors. A Realtek 8125BG 2.5G LAN controller handles wired networking, paired with AMD-branded Wi-Fi 6E and Bluetooth 5.3. Audio uses a Realtek ALC897 codec with 7.1-channel support. Against the Gigabyte B850M AORUS STEALTH in this catalog, the PRO B650M-A WiFi is a chipset generation behind and limited to two M.2 slots, making it the budget alternative for builders who don't need PCIe 5.0 storage.
