Model B850 GAMING PLUS WIFI PZ

  • Cleaner front view with back-connect design moving power and fan headers to the rear
  • Easier cable management by eliminating front-to-back cable routing across the motherboard
  • DDR5 memory support up to 8200 MT/s overclocked for Ryzen 9000 series processors
  • PCIe 5.0 x4 M.2 slot delivering up to 128GB/s bandwidth for fastest storage
  • Wi-Fi 7 with 320MHz channel enabling 5.8Gbps maximum wireless transmission speed

AM5 Back-Connect Motherboard

The MSI B850 GAMING PLUS WIFI PZ is an ATX motherboard built on the AMD B850 chipset for AM5 socket processors. It supports Ryzen 7000 Series, Ryzen 8000 Series and Ryzen 9000 Series CPUs. The back-connect design moves power, fan and storage headers to the rear for a cleaner front appearance and simpler cable routing.

DDR5 256GB Capacity With EXPO

Four 288-pin slots accept up to 256 GB of dual-channel DDR5 memory. JEDEC speeds run at 4800-5600 MT/s while AMD EXPO profiles reach 5600-8200 MT/s overclocked. With Ryzen 9000 Series processors a single-rank single-DIMM configuration can exceed 8200 MT/s, while two-rank or two-DIMM setups top out lower at 6400 MT/s or below.

PCIe 5.0 M.2 And Wi-Fi 7 Connectivity

The primary M.2 slot runs at PCIe 5.0 x4 from the CPU for 2280 or 2260 drives. A second CPU-linked slot provides PCIe 4.0 x4 and a chipset slot offers PCIe 4.0 x2. Four SATA 6Gb/s ports support RAID 0, 1, 10 and NVMe RAID 0, 1, 5. Wi-Fi 7 with a 320 MHz channel delivers up to 5.8 Gbps alongside 5Gb LAN and USB 10Gbps Type-C.
