MSI PRO B850M-P WIFI AMD B850 AM5 DDR5 Wi-Fi 7 Micro-ATX Motherboard
Product Overview
The MSI PRO B850M-P WIFI uses the AMD B850 chipset and AM5 socket for AMD Ryzen 9000, 8000 and 7000 Series desktop processors. Its Micro-ATX, 243.84 × 243.84 mm layout is designed for a case that supports that form factor. Confirm the exact processor against MSI’s CPU support list and the installed BIOS before building.
Its memory configuration is 4 × DDR5 UDIMM, dual channel, up to 256GB; AMD EXPO; 4800–5600 MT/s JEDEC, up to 8200+ MT/s OC by CPU/configuration. Overclocked data rates are ceilings for suitable hardware, not guaranteed speeds for every CPU and DIMM combination. Check MSI’s memory compatibility list when planning a high-capacity or high-speed kit.
For a graphics card and expansion, the board provides Primary x16-shaped slot: PCIe 5.0 x16 with Ryzen 9000/7000, PCIe 4.0 x8 with selected Ryzen 8000; three PCIe 3.0 x16-shaped slots (x1). The board’s HDMI or DisplayPort output depends on a processor with integrated graphics; a processor without it needs a discrete graphics card for display output.
For storage, it provides M2_1 PCIe 5.0 x4 or PCIe 4.0 x4 by CPU; M2_2 PCIe 4.0 x4 or x2 by CPU; M2_3 PCIe 4.0 x2; 4 × SATA 6Gb/s. This gives the build both M.2 and SATA options, subject to the slot and processor restrictions listed in MSI’s specifications.
Network connections are Realtek 5GbE; Wi-Fi 7; Bluetooth 5.4. Display connections are HDMI 2.1 and DisplayPort 1.4, up to 4K/60Hz; require CPU integrated graphics. Its USB provision is Rear: 1 × USB 10Gbps Type-A, 1 × USB 10Gbps Type-C, 2 × USB 5Gbps Type-A, 4 × USB 2.0; front headers: 1 × USB 10Gbps Type-C, 4 × USB 5Gbps Type-A, 4 × USB 2.0. The 6GHz Wi-Fi band, where applicable, depends on local rules and operating-system support.
Cooling connections include 1 CPU fan, 1 combo pump/system fan, 3 system fan headers; 3 addressable RGB and 1 RGB header. Audio uses Realtek ALC897, 7.1-channel HD audio. This is a practical fit for a Micro-ATX build when its processor, storage and rear I/O match the parts you plan to install.
