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+
• 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

 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)
  • 1x JRGB (standard RGB)
• Fan Headers:
  • CPU, Pump/Combo, 4x SYS Fans
• Power:
  • ATX_PWR, 2x CPU_PWR, PCIE_PWR (8-pin)
• TPM 2.0, JDASH tuning header, chassis intrusion, COM, JAUD
• EZ Debug LEDs (x4)
• Thunderbolt 5 card header not listed here (unlike Intel board)
