Our take on the MSI MAG B850 Tomahawk MAX WiFi Motherboard

The MSI MAG B850 Tomahawk MAX WiFi is a mid-range AM5 motherboard built for AMD Ryzen 7000, 8000, and 9000 processors. It stands out with a 14+2+1 80A VRM, PCIe 5.0 x16, four M.2 slots (two Gen5), Wi-Fi 7, and 5Gbps Ethernet. It suits gamers and builders who want strong power delivery and fast storage without flagship pricing. Compared with rivals like the ASUS TUF Gaming B850-Plus WiFi, it offers more M.2 Gen5 slots and faster LAN, but its rear USB layout lacks Thunderbolt and its VRM heatsinks are larger than some cases allow. Reviewers praise its value and cooling, though some note the board is picky with high-speed DDR5 kits.
