MSI PRO B860-P WiFi (LGA1851/Intel B860/ATX/Three M.2 Slots/5Gbps LAN/Wi-Fi 7) Review
The PRO B860-P WiFi is MSI's value-tier ATX board for Intel Core Ultra Series 2 processors, giving budget builders a PCIe 5.0 GPU slot and unusually fast 5Gbps LAN for a PRO-series board.
MSI does not publish an exact VRM phase count for this board, but it is rated for Core Ultra 5 and Core Ultra 7 chips at stock clocks without thermal throttling. Four DDR5 UDIMM slots support up to 256GB total capacity, with 1DPC 1R 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. Storage covers three M.2 slots: one PCIe 5.0 x4 and two PCIe 4.0. A Realtek 8126 controller provides 5Gbps LAN, paired with Intel Wi-Fi 7 rated up to 5.8Gbps and Bluetooth 5.4. Audio uses a Realtek ALC897 codec with 7.1-channel support. Against the MSI PRO Z890-P WiFi also in this batch, the PRO B860-P WiFi trades the Z890 chipset's higher-end features for a lower B860 price while matching its 5Gbps LAN and Wi-Fi 7 support.
