MSI MAG B850 Tomahawk WiFi7 ATX Motherboard

The MSI MAG B850 Tomahawk WiFi 7 is an ATX form-factor motherboard built on the AMD B850 chipset with an AM5 socket, designed to support AMD Ryzen 9000, 8000, and 7000 series desktop processors. It targets builders who want a stable, feature-rich platform without moving to a premium X-series board. At the heart of its power delivery is a 14+2+1 Duet Rail Power System supported by dual 8-pin CPU power connectors and an additional 8-pin PCIe supplemental power connector. The 6-layer PCB uses 2 oz thickened copper traces alongside server-grade materials, lending the board thermal and electrical headroom for demanding workloads. Thermal management is addressed by the Frozr Guard heatsink system, which includes an extended MOSFET heatsink with 7 W/mK rated thermal pads, additional choke thermal pads, and the EZ M.2 Shield Frozr II covers to keep NVMe drives cool under sustained loads. On the connectivity front, the board ships with a genuine Wi-Fi 7 module accompanied by Bluetooth 5.4, and a 5G LAN port for wired networking. The primary PCIe slot runs at PCIe 5.0 x16 for Ryzen 9000 and 7000 series CPUs, while Ryzen 8000-series CPUs use PCIe 4.0 modes on the same slot. A second PCIe x16 physical slot operates at PCIe 4.0 x4 via the chipset, and a PCIe 3.0 x1 slot rounds out expansion. Memory support covers DDR5 in dual-channel configuration up to 8200+ MT/s (OC) with AMD EXPO compatibility. Non-ECC, unbuffered DDR5 is supported, including CUDIMM in Clock Driver bypass mode, with a maximum capacity of 256 GB. The back panel provides USB 20Gbps Type-C, multiple USB 10Gbps Type-A and Type-C ports, USB 5Gbps Type-A, USB 2.0, an optical S/PDIF output, HDMI video output, Clear CMOS and Flash BIOS buttons, and 5G LAN. Internal headers include a USB 10Gbps Type-C header, USB 5Gbps Type-A headers, four USB 2.0 ports, three Addressable V2 RGB headers (JARGB_V2), one RGB header (JRGB), a TPM 2.0 header, and six system fan connectors alongside dedicated CPU and pump headers. Audio Boost 5 delivers high-fidelity onboard audio.
