MSI Pro B850M-G DDR5 AMD Motherboard

The MSI Pro B850M-G DDR5 is a Micro-ATX motherboard built on the AMD B850 chipset for the AM5 socket, supporting AMD Ryzen 9000, 8000, and 7000 series desktop processors. Its understated silver-accented design sits comfortably in both white and black chassis, making it a versatile foundation for professional workstation and productivity-focused builds alike. Power delivery is handled by a Direct 7+2+1 digital phase VRM fed through an 8-pin CPU power connector, complemented by a 6-layer PCB constructed with 2 oz thickened copper and server-grade materials. Thermal management across the VRM and storage areas is reinforced by an extended heatsink with MOSFET thermal pads rated at 7 W/mK, supplementary choke thermal pads, and an M.2 Shield Frozr over the primary NVMe slot. Memory support spans two DDR5 UDIMM slots with a maximum capacity of 128 GB. Using Ryzen 9000 series processors, a single-rank single-module configuration can reach DDR5 8200+ MT/s through overclocking, while dual-rank configurations can achieve 8000+ MT/s. The board also supports AMD EXPO profiles and standard JEDEC speeds from 4800 to 5600 MT/s natively. For storage, the primary M.2_1 slot (CPU-connected) supports PCIe 5.0 x4 with Ryzen 9000 and 7000 processors, while M.2_2 (also CPU-connected) tops out at PCIe 4.0 x4. Four SATA 6 Gbps ports round out the storage options, and the board supports RAID 0, 1, and 10 for SATA devices and RAID 0 and 1 for NVMe drives. Graphics connectivity on the primary PCIe x16 slot runs at PCIe 5.0 x16 with Ryzen 9000 and 7000 CPUs, dropping to PCIe 4.0 x8 or x4 with select Ryzen 8000 SKUs. A secondary PCIe x16 physical slot operates at PCIe 4.0 x4 from the chipset. Networking is provided by a Realtek 8126VB 5G LAN controller. Display outputs include HDMI 2.1 (4K 60 Hz) and DisplayPort 1.4 (4K 60 Hz), both available only when using a processor with integrated graphics. Audio is handled by the Realtek ALC897 codec delivering 7.1-channel HD audio. USB connectivity includes, at the rear: two USB 2.0, three USB 5 Gbps Type-A, and one USB 5 Gbps Type-C. Internal headers add four USB 2.0, two USB 5 Gbps Type-A, and one USB 10 Gbps Type-C. RGB customisation is supported through three ARGB V2 headers and one standard RGB header. The board ships with EZ M.2 Clip II and EZ PCIe Clip II for tool-reduced installation.
