AM5 Motherboard for Ryzen 7000 8000 9000 Series

The MSI B850 GAMING PLUS WIFI6E 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 desktop CPUs. Four 288 pin DDR5 slots accept up to 256GB of unbuffered non ECC memory with AMD EXPO profiles. The board includes Wi-Fi 6E and a Realtek 8125D 2.5G LAN controller for wired and wireless networking.

Straightforward ATX Installation

Standard ATX mounting holes and labelled headers make the physical install routine for any builder familiar with the form factor. The primary PCI_E1 slot runs at PCIe 4.0 x16 from the CPU for Ryzen 9000 and 7000 series, dropping to x8 for Ryzen 8700 8600 8400 series. A second x4 slot PCI_E3 comes from the chipset at PCIe 4.0 while PCI_E2 is a PCIe 3.0 x1 slot. Dual 8 pin CPU power connectors feed the 12 Duet Rail P-PAK power system so ensure your PSU cables reach cleanly.

Check CPU Generation PCIe Lane Split

Verify which Ryzen generation you will install because the top slot lane count changes between series. M.2_1 is sourced from the CPU and supports PCIe 5.0 x4 for 22110 and 2280 devices while M.2_2 supports PCIe 4.0 x4 for 2280 and 2260 drives. Four SATA 6Gb/s ports provide RAID 0 1 10 and the M.2 NVMe RAID supports RAID 0 1. Confirm your cooler clears the extended PWM heatsink and that your case fits ATX dimensions.
