3

4 × DDR5 DIMM slots — Right

Dual-channel DDR5, up to 256 GB. With Ryzen 9000, MSI rates 8200+ MT/s for one single-rank DIMM per channel, 6400+ MT/s for two, AMD EXPO and A-XMP profiles, and Latency Killer.

4

Lightning Gen5 M.2 — Under the white heatsink

M.2_1 at PCIe 5.0 x4 from the CPU under the M.2 Shield Frozr heatsink, 2280/2260, with the tool-free EZ M.2 Clip II.

5

PCIe 4.0 x16 slot with Steel Armor — Mid board

Wired to the CPU at PCIe 4.0 x16 on Ryzen 9000/7000 and reinforced with Steel Armor, plus two PCIe 3.0 x1 slots from the chipset and M.2_2 at PCIe 4.0 x4.

6

Chipset, SATA and headers — Lower right

B850 chipset under the GAMING heatsink, 4 × SATA 6Gb/s, a front USB-C 10Gbps header, 3 ARGB V2 headers, the EZ Conn JAF_1 header and the EZ Debug LEDs.

Will It Fit Your Build?

Check these before you add to cart

!

Graphics slot is PCIe 4.0

The x16 slot runs at PCIe 4.0 x16, not 5.0. Any current graphics card works in it; PCIe 5.0 on this board is the Lightning Gen5 M.2 slot for storage.

!

Power supply — two 8-pin CPU cables

MSI fits two 8-pin CPU (EPS) connectors. Check your power supply has both, plus the 24-pin ATX cable.

✓

Processor

AMD Ryzen 9000, 8000 and 7000 Series on socket AM5. Ryzen 8000 chips run M.2_1 at PCIe 4.0 x4, and Ryzen 8500/8300 run the x16 slot at PCIe 4.0 x4.

✓

Memory

Four DDR5 slots, up to 256 GB. Two sticks reach the highest rated speeds; four sticks are rated to 6400+ MT/s (single-rank) on Ryzen 9000.

Technical & Policy Q&A

Common questions about the B850M GAMING PLUS WIFI6E

Is the graphics card slot PCIe 5.0?+

No. MSI's specification lists the x16 slot (PCI_E2) at PCIe 4.0 x16 with Ryzen 9000 and 7000, x8 with Ryzen 8700/8600/8400 and x4 with Ryzen 8500/8300. The PCIe 5.0 lanes go to the M.2_1 Lightning Gen5 slot for an NVMe SSD.

Does the Wi-Fi 6E work out of the box?+

The Wi-Fi 6E and Bluetooth 5.3 module comes pre-installed in the board's M.2 Key-E slot, and the EZ Antenna is in the box. MSI notes that 6 GHz depends on each country's regulations and is ready in Windows 11.

Which memory should I buy for it?+

Any non-ECC DDR5 UDIMM kit. With Ryzen 9000, MSI rates 8200+ MT/s for one single-rank stick per channel (two sticks) and 6400+ MT/s with four single-rank sticks. The board holds up to 256 GB and supports AMD EXPO and A-XMP profiles.
