MSI B850M Gaming Plus Wifi7 DDR5 AMD Motherboard

The MSI B850M Gaming Plus WiFi 7 is a Micro-ATX motherboard built on the AMD B850 chipset for the AM5 socket, designed to support AMD Ryzen 9000, 8000, and 7000 series desktop processors. It pairs a modern DDR5 dual-channel memory subsystem with extensive connectivity options, making it a capable platform for gaming and productivity workloads alike. At the heart of its power delivery is a Direct 8+2+1 phase design using 60A Smart Power Stages, fed by dual 8-pin and 4-pin CPU power connectors. The 6-layer PCB uses 2oz thickened copper and server-grade materials, supporting stability under sustained loads. MSI's Frozr Guard thermal solution integrates an extended heatsink, MOSFET thermal pads rated at 7W/mK, additional choke thermal pads, and the EZ M.2 Shield Frozr II to keep critical components within operating temperatures. Memory support extends to DDR5 at speeds up to 8200+ MT/s via overclocking, with a maximum capacity of 256 GB across two DIMM slots. The board supports AMD EXPO profiles, JEDEC speeds, and non-ECC unbuffered modules. CUDIMM support is available in clock driver bypass mode only, with compatibility subject to CPU series and BIOS version. Connectivity is a strong point. The primary PCIe slot runs at PCIe 5.0 x16 from the CPU for Ryzen 9000 and 7000 series, while the onboard M.2 solution supports Lightning Gen 5 x4 speeds. Networking is handled by a 5G LAN port alongside Wi-Fi 7 and Bluetooth 5.4, offering both wired and wireless high-bandwidth options. The rear I/O panel includes HDMI and DisplayPort 1.4 outputs, USB 10 Gbps Type-A and Type-C ports, USB 5 Gbps Type-A ports, a Clear CMOS button, and a Flash BIOS button for convenient maintenance. Internally, the board provides headers for four USB 2.0 ports, two USB 5 Gbps Type-A ports, one USB 10 Gbps Type-C port, three ARGB V2 connectors, one standard RGB connector, and fan headers including a CPU fan, combo pump/system fan, and three system fans. EZ DIY features — including EZ M.2 Shield Frozr II, EZ M.2 Clip II, EZ PCIe Clip II, and EZ Antenna — simplify component installation and cable management. TPM 2.0 header support is included for platform security requirements. **Verified Specifications** - Form Factor: Micro-ATX - Chipset: AMD B850 - Socket: AM5 - Compatible CPUs: AMD Ryzen 9000, 8000, 7000 series - Memory: DDR5 Dual Channel, up to 256 GB, up to 8200+ MT/s (OC) - Primary PCIe Slot: PCIe 5.0 x16 (CPU) - M.2: Lightning Gen 5 x4 supported - Wireless: Wi-Fi 7, Bluetooth 5.4 - Wired LAN: 5G LAN - Rear USB: USB 10 Gbps (Type-A x2, Type-C x1), USB 5 Gbps (Type-A x2) - Display Output: HDMI, DisplayPort 1.4 - VRM: Direct 8+2+1 phases, 60A SPS - Warranty: 3 Years
