MSI PRO B860M-A WiFi

The PRO B860M-A WiFi is the micro-ATX sibling of the PRO B860-P WiFi, giving compact-case Intel Core Ultra Series 2 builders the same PCIe 5.0 GPU slot and 5Gbps LAN in a smaller footprint.

MSI does not publish an exact VRM phase count for this board; it shares the same general power delivery tier as its ATX sibling and is rated for Core Ultra 5 and Core Ultra 7 chips at stock clocks. Four DDR5 UDIMM slots support up to 256GB total capacity, with single-channel single-rank overclocking rated up to 8800+ MT/s. Expansion includes four PCI-E x16 slots: a PCIe 5.0 x16 from the CPU and three PCIe 4.0 slots from the chipset (x1, x1, x4). Storage covers three M.2 slots: one PCIe 5.0 x4 from the CPU and two PCIe 4.0 slots from the chipset. A Realtek 8126 controller provides 5Gbps LAN, paired with Intel Wi-Fi 7 and Bluetooth 5.4. Audio uses a Realtek ALC897 codec with 7.1-channel support. Against its ATX sibling MSI PRO B860-P WiFi in this batch, the PRO B860M-A WiFi trims the board to a micro-ATX footprint while keeping an identical M.2 and networking configuration, making it the pick for compact cases.
