AM5 B850 motherboard for Ryzen 7000.

This micro-ATX board uses the AMD B850 chipset and the AM5 socket to support Ryzen 7000, 8000 and 9000 series processors. Four DDR5 slots accept up to 256 GB of memory running at JEDEC speeds of 5600 MT/s or 4800 MT/s and overclocked speeds up to 8200 MT/s. The layout provides a PCIe 5.0 x16 slot and two CPU-attached M.2 slots for high-bandwidth graphics and storage.

Thermals, noise and power delivery

Twin 8-pin CPU power connectors and a dedicated 8-pin PCIe power connector feed the voltage regulator modules for stable current under load. Multiple system-fan headers, a pump header and an ARGB-plus-fan-plus-USB 2.0 header allow flexible cooling configurations. The pre-installed I/O shield and heatsinks on the VRM and M.2 slots help dissipate heat without adding active noise sources.

Wi-Fi 7 module and USB 20Gbps front header

A Wi-Fi 7 module sits in the onboard M.2 Key-E slot and delivers 2.4 GHz, 5 GHz and 6 GHz operation with 320 MHz channels and MU-MIMO up to 5.8 Gbps using 802.11 a/b/g/n/ac/ax/be. Bluetooth 5.4 is integrated on the same module. The front-panel USB header supplies a 20 Gbps Type-C port, while the rear I/O includes 10 Gbps Type-A, 10 Gbps Type-C, 5 Gbps Type-A, 2.0 ports, 5 Gbps LAN, HDMI, optical S/PDIF and a Flash BIOS button.

Questions about this item

How do I install the Wi-Fi 7 module on this board?

The Wireless module is pre-installed in the M.2 (Key-E) slot, so no separate installation step is required.

What maintenance will the pre-installed Wi-Fi 7 module need later?

No routine maintenance is required for the pre-installed module; firmware updates are delivered through the BIOS when released by MSI.

What thermal limit appears first on the M.2_1 slot under sustained PCIe 5.0 x4 loads?

The M.2_1 slot runs from the CPU at PCIe 5.0 x4 for Ryzen 9000/7000 Series processors; the onboard M.2 shield acts as the primary heatsink to manage drive temperatures.
