Singular Expert Insight
Choose this model if you want a compact AM5 motherboard for a clean back-connect build with Wi-Fi 7, 5G LAN, PCIe 5.0 graphics and Gen5 M.2 storage. If your case does not support back-connect motherboards, choose a standard-layout B850M board instead.

Buyer’s Guide

Buy it if
You are building a clean AM5 system in a compatible back-connect case and want Wi-Fi 7, 5G LAN, DDR5 and PCIe 5.0 support.
