MSI B850M Gaming Pro Wifi6e DDR5 AMD Motherboard

The MSI B850M Gaming Pro WiFi 6E is a Micro-ATX motherboard built on the AMD B850 chipset with an AM5 socket, designed to support AMD Ryzen 9000, 8000, and 7000 series desktop processors. It is engineered for gamers and PC builders who demand high-speed connectivity, robust power delivery, and future-ready storage options in a compact form factor. At the heart of its power architecture is a Direct 8+2+1 phase VRM design featuring 55A DrMOS components and dual 8-pin CPU power connectors. This configuration, combined with MSI’s Core Boost and Memory Boost technologies, ensures stable voltage delivery under sustained gaming and productivity workloads. The 6-layer PCB is constructed with 2oz thickened copper traces to improve signal integrity and heat dissipation. For memory, the board provides four DDR5 UDIMM slots supporting up to 256GB of capacity. JEDEC speeds range from 4800 to 5600 MT/s, while overclocking via AMD EXPO or XMP can push speeds from 5600 MT/s up to 8200+ MT/s in the right single-rank, single-DIMM-per-channel configuration. Dual-channel operation is fully supported. Storage options include two M.2 slots: the primary slot (M.2_1) runs from the CPU and supports PCIe 5.0 x4 when paired with Ryzen 9000 or 7000 series processors, while the secondary slot (M.2_2) supports up to PCIe 4.0 x4. Both slots accept 2280 and 2260 form-factor drives. Four SATA 6Gb/s ports round out local storage, with RAID 0, 1, and 10 support for SATA devices and RAID 0 and 1 for NVMe. Networking is handled by a Realtek 8125D 2.5G wired LAN controller paired with an integrated Wi-Fi 6E module pre-installed in the M.2 Key-E slot. The wireless solution supports the 2.4GHz, 5GHz, and 6GHz bands at up to 160MHz channel width with peak throughput of up to 2.4Gbps, along with MU-MIMO TX/RX and 802.11a/b/g/n/ac/ax standards. Bluetooth 5.3 is also included. Display output is available via one HDMI 2.1 port (up to 4K 60Hz) and one DisplayPort 1.4 port (up to 4K 60Hz), both active only when using a Ryzen processor with integrated graphics. Audio is provided by a Realtek ALC897 codec delivering 7.1-channel HD audio. USB connectivity is extensive: the rear panel offers four USB 5Gbps Type-A, three USB 10Gbps Type-A, and one USB 10Gbps Type-C ports. Internal headers add four USB 2.0, two USB 5Gbps Type-A, and one USB 10Gbps Type-C front-panel ports. RGB enthusiasts will find three addressable ARGB V2 headers and one standard RGB header, plus four EZ Debug LEDs and one EZ Memory Detection LED for fast troubleshooting. MSI’s EZ DIY features — including EZ PCIe Clip II, EZ M.2 Clip II, EZ Antenna, and the EZ Conn header — simplify installation and cable management. The Frozr Guard thermal solution includes an extended VRM heatsink with 7W/mK MOSFET thermal pads, additional choke thermal pads, and per-slot M.2 Shield Frozr heatsinks to manage NVMe drive temperatures.
