MSI PRO B860M-P WIFI6E Intel B860 LGA1851 DDR5 Wi-Fi 6E Micro-ATX Motherboard

Product Overview

The MSI PRO B860M-P WIFI6E uses the Intel B860 chipset and LGA1851 socket for Intel Core Ultra processors (Series 2). 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; XMP 3.0; 4800–6400 MT/s JEDEC, up to 8800+ MT/s OC by 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 PCIe 5.0 x16 (x16 electrical, CPU); PCIe 4.0 x16-shaped slot (x4, chipset). 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 1 × M.2 PCIe 5.0 x4; 1 × M.2 PCIe 4.0 x4; 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 2.5GbE; Wi-Fi 6E; Bluetooth 5.3. Display connections are HDMI 2.1, 2 × DisplayPort 1.4 and VGA; require CPU integrated graphics. Its USB provision is Rear: 3 × USB 5Gbps Type-A, 2 × USB 2.0; front headers: 2 × USB 5Gbps Type-A, 1 × USB 5Gbps Type-C, 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, 2 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.
