MSI B850 Gaming Pro Wifi6E DDR5 AMD Motherboard

The MSI B850 Gaming Pro WiFi 6E is an ATX-form-factor motherboard built on the AMD B850 chipset, designed for AMD Ryzen 9000, 8000, and 7000 series desktop processors via the AM5 socket. It targets gamers and PC builders who want a capable platform with fast wireless, high-bandwidth storage, and a robust power delivery stage without stepping up to a full enthusiast chipset. On the memory side, four DDR5 UDIMM slots support up to 256 GB of capacity. With Ryzen 9000 processors, DDR5 can reach up to 8200 MT/s in a single-rank, single-DIMM-per-channel configuration using overclocking profiles, including support for AMD EXPO. JEDEC speeds range from 4800 to 5600 MT/s depending on configuration. Dual-channel operation is supported throughout, and the board accepts non-ECC unbuffered memory as well as CUDIMM in clock-driver bypass mode. Storage options include two M.2 slots: the primary slot (M.2_1) runs directly from the CPU and supports up to PCIe 5.0 x4 on Ryzen 9000 and 7000 processors, accommodating 2280 and 22110 form factors. The secondary slot (M.2_2) supports up to PCIe 4.0 x4 from the CPU. Four SATA 6Gbps ports complete the storage array, with RAID 0, 1, and 10 support for SATA devices and RAID 0/1 for NVMe. The primary PCIe x16 slot operates at PCIe 4.0 x16 for Ryzen 9000 and 7000 processors, with reduced bandwidth configurations for Ryzen 8000 series APUs. Three additional PCIe slots are provided via the chipset. Wireless connectivity is handled by a pre-installed M.2 Key-E Wi-Fi 6E module supporting 2.4 GHz, 5 GHz, and 6 GHz bands (6 GHz band subject to regional regulations), with MU-MIMO and up to 2.4 Gbps throughput. Bluetooth 5.3 is also included. Wired networking uses a Realtek 8125D 2.5G LAN controller. The USB layout spans rear and front headers: the rear panel provides three USB 10 Gbps Type-A ports, one USB 10 Gbps Type-C, and four USB 5 Gbps Type-A ports. Front headers add two USB 5 Gbps Type-A and one USB 10 Gbps Type-C connector, plus four USB 2.0 ports. Audio is delivered by a Realtek ALC897 codec with 7.1-channel high-definition output. Display outputs on the rear panel include one HDMI 2.1 (up to 4K 60 Hz) and one DisplayPort 1.4 (up to 4K 60 Hz), available only with processors featuring integrated graphics. The power delivery stage uses a 12+2+1 Duet Rail configuration with 55A DrMOS components and dual 8-pin CPU power connectors. The PCB is ATX-sized at 243.84 mm × 304.8 mm and built with a 6-layer, 2 oz copper design. Thermal management includes an extended heatsink with 7 W/mK MOSFET thermal pads, choke thermal pads, and M.2 Shield Frozr heatsinks.
