Description
AMD B850 mATX Motherboard for AM5 — No Wi-Fi, 5G LAN, USB 10Gbps, Triple M.2 with PCIe 5.0 Gen5, DDR5 8200+ OC, Supplemental PCIe Power, Silver Design, AI-PC Ready, Ryzen 9000 / 8000 / 7000 Ready.
The MSI PRO B850M-P is the wired-only mATX entry in the PRO B850 family — for builders who don't need Wi-Fi and want to save cost without sacrificing core features. It sports the same harmonious silver colour scheme as the WIFI variant, along with Realtek 5G LAN, USB 10Gbps rear Type-C and Type-A, one CPU-direct PCIe 5.0 x4 M.2 Gen5 with EZ M.2 Shield Frozr II, one PCIe 4.0 x4 M.2 (CPU), one PCIe 4.0 x2 M.2 (Chipset), Supplemental PCIe Power 8-pin, and MSI's EZ DIY suite — excellent value for AM5 productivity and gaming mATX builds.
