Description
MSI B850 GAMING PLUS WIFI motherboard
Core Platform Specs:
- Chipset: AMD B850
- Socket: AM5
- CPU Support: Ryzen™ 9000 / 8000 / 7000 Desktop CPUs
(Socket longevity is real here — AM5 is future-ready.)
Memory:
- 4x DDR5 UDIMM, up to 256GB
- Speeds:
- Up to 8200+ MT/s (OC) w/ Ryzen 9000
- 1DPC 1R: 8200+
- 1DPC 2R: 6400+
- 2DPC 1R: 6400+
- 2DPC 2R: 4800+
- Up to 8200+ MT/s (OC) w/ Ryzen 9000
- Supports EXPO™, JEDEC, manual OC, Dual-Channel
- CUDIMM supported (Clock Driver bypass only)
- Like Intel boards, memory speed depends on the CPU and module setup — check that QVL.
PCIe Slots:
- 4x PCIe x16 slots:
- PCI_E1:
- PCIe 5.0 x16 (9000/7000 series)
- PCIe 4.0 x8 or x4 (8000/8500/8300 series)
- PCI_E2 (x1, Gen 3), E3 (x4, Gen 4), E4 (x1, Gen 3) — all from chipset
- E2, E3, E4 share bandwidth — E3 drops to x2 if E2 or E4 is used
- PCI_E1:
Storage:
- 3x M.2 Slots:
- M.2_1 (CPU): PCIe 5.0 x4 (9000/7000) / PCIe 4.0 x4 (8000)
- M.2_2 (CPU): PCIe 4.0 x4, supports 22110
- M.2_3 (Chipset): PCIe 4.0 x2
- 4x SATA 6Gbps
- RAID 0 & 1 for NVMe
M.2_1 at PCIe 5.0 is ideal for cutting-edge Gen5 SSDs. The second slot supports longer 22110 drives (good for prosumer NVMe SSDs with big heatsinks).
Audio:
- Realtek ALC897, 7.1 Channel HD Audio
(Basic, but decent — like the Intel board.)
Graphics Output:
- 1x DisplayPort 1.2 — 4K@60Hz
(Only works if you use a Ryzen CPU with integrated graphics — think 8700G, 8600G, etc.)
USB I/O:
- Rear:
- 4x USB 2.0
- 1x USB 5Gbps Type-A
- 1x USB 10Gbps Type-A
- 2x USB 10Gbps Type-C
- Front Headers:
- 4x USB 2.0
- 4x USB 5Gbps Type-A
- 1x USB 5Gbps Type-C
Networking:
- LAN: Realtek 8126VB – 5Gbps Ethernet
- Wi-Fi: Wi-Fi 7 (802.11be)
- MU-MIMO, 2.4/5/6GHz, up to 5.8Gbps
- Bluetooth 5.4 ready (Windows 11 24H2)
Other Features & Internal Headers:
- RGB Headers:
- 3x JARGB V2 (Addressable)
