Product Note
This motherboard requires an AMD AM5 processor and DDR5 memory. It is not compatible with Intel processors or DDR4 DIMMs. Verify the exact CPU model against ASUS’s compatibility list and check BIOS requirements before purchase.
PCIe and M.2 operating modes vary by processor generation. With supported Ryzen 7000 and 9000 Series CPUs, the primary graphics slot supports PCIe 5.0 x16 and the first M.2 socket supports PCIe 5.0 x4. Ryzen 8000 Series processors may use reduced PCIe lane configurations and lower supported M.2 speeds.
Full Wi-Fi 7 functionality requires Windows 11 version 24H2 or later according to ASUS. Earlier Windows 11 versions are limited to Wi-Fi 6E, while Windows 10 wireless support depends on the installed Wi-Fi module and its available drivers. Access to the 6GHz band is subject to local regulations. HDMI and DisplayPort outputs require a processor with integrated graphics.
Frequently Asked Questions
Q1: Which processors are compatible with the ASUS TUF GAMING B850M-PLUS WIFI7?
