MSI MAG B850 Tomahawk Max Wifi DDR5 AMD Motherboard

The MSI MAG B850 Tomahawk Max WiFi is an ATX motherboard built on the AMD B850 chipset, designed for Socket AM5 processors. It supports AMD Ryzen 9000, 8000, and 7000 series desktop processors, making it a forward-compatible platform for current and prior-generation Ryzen builds. At the heart of its power delivery is a 14+2+1 Duet Rail Power System featuring dual 8-pin CPU power connectors and 80A Smart Power Stage components. The board is constructed on an 8-layer PCB using 2oz thickened copper and server-grade materials, contributing to robust power integrity under sustained loads. Memory support spans four DDR5 UDIMM slots with a maximum capacity of 256GB. In JEDEC configuration, speeds range from 4800 to 5600 MT/s, while overclocked profiles reach up to 8400+ MT/s (1DPC 1R) via AMD EXPO or manual OC. Dual-channel mode, Non-ECC unbuffered memory, and CUDIMM (clock driver bypass mode) are all supported. Storage options are extensive: four M.2 slots are provided, with M2_1 and M2_2 sourced from the CPU and capable of PCIe 5.0 x4 (on Ryzen 9000/7000), plus four SATA 6Gbps ports. RAID 0, 1, and 10 are supported for M.2 NVMe devices. The primary PCIe x16 slot (PCI_E1) runs at PCIe 5.0 x16 for Ryzen 9000/7000 processors, enabling next-generation GPU compatibility. Networking is handled by a Realtek 8126VB 5G wired LAN controller alongside an integrated Wi-Fi 7 module (802.11be) supporting 2.4GHz, 5GHz, and 6GHz bands up to 5.8Gbps, with MU-MIMO and MLO. Bluetooth 5.4 is also included. Audio is powered by the Realtek ALC4080 codec delivering 7.1-channel output with up to 32-bit/384kHz playback on the front panel and S/PDIF output. USB connectivity is comprehensive, including a front-panel USB 20Gbps Type-C header, rear USB 10Gbps Type-C ports, and USB 2.0 ports front and rear.
