Overview
The MSI MAG B850 TOMAHAWK WIFI is a high-performance ATX motherboard designed for gamers and enthusiasts building systems around AMD Ryzen 9000, 8000, and 7000 series processors. Built on the AMD B850 chipset with Socket AM5 compatibility, this board delivers stability and durability with a robust 14+2+1 Duet Rail Power System featuring 80A Smart Power Stages and dual 8-pin CPU power connectors.
The motherboard excels in connectivity with Wi-Fi 7 support, 5G LAN, PCIe 5.0 slot, and USB 20Gbps Type-C connectivity. Memory support includes four DDR5 UDIMM slots supporting speeds up to 8200+ MT/s (OC) with EXPO and A-XMP profiles. Storage options feature one PCIe Gen 5 M.2 slot and two PCIe Gen 4 M.2 slots for ultra-fast NVMe drives.
Thermal management is handled by an extended heatsink design, EZ M.2 Shield Frozr II, 7W/mK thermal pads, and a 6-layer server-grade PCB with 2oz copper. The board includes numerous DIY-friendly features such as EZ M.2 installation without screws, EZ PCIe Release, Clear CMOS button, and Flash BIOS button for hassle-free assembly and troubleshooting.
Audio quality is enhanced with the Realtek ALC4080 codec, Audio Boost 5, and isolated audio signal design. The Click BIOS X interface provides intuitive access to overclocking features including Game Boost, AI Boost, and Performance Preset options.
