Verdict

The MSI MAG B850M MORTAR WIFI is a robust micro-ATX motherboard built on the AM5 socket, supporting AMD Ryzen 9000, 8000, and 7000 series processors. It features a high-performance 12+2+1 duet rail power system with 60A Smart Power Stages and supports up to 256GB of DDR5 memory at speeds exceeding 8200+ MT/s (OC). Key specifications include a primary PCIe 5.0 x16 slot, triple M.2 connectors (including two Gen5 x4 slots), 5G LAN, and Wi-Fi 7 with Bluetooth 5.4. Main pros include its advanced EZ DIY features like the tool-less EZ M.2 Shield Frozr II and the EZ PCIe Release button, alongside high-end Realtek ALC4080 audio and excellent VRM cooling. On the downside, it lacks USB4 ports, and the third M.2 slot located on the rear of the PCB lacks a native heatsink and is limited to PCIe 4.0 x2 speeds.
