CPU + Ryzen 9 9950X3D

  • Stable power for heavy workloads
  • 14+2+1 80A DrMOS stages with 8-layer PCB
  • One PCIe 5.0 M.2 plus two PCIe 4.0 M.2 slots with large heatsink
  • Wi-Fi 6E and 2.5Gb LAN plus rear USB 20Gbps Type-C and front USB 10Gbps Type-C
  • 16-core Ryzen 9 9950X3D with 128MB L3 cache and Radeon graphics

AM5 Motherboard and Ryzen 9 9950X3D Combo

This bundle pairs an ASUS TUF Gaming B850M-Plus WiFi motherboard with an AMD Ryzen 9 9950X3D processor. The board uses the AMD B850 chipset on an AM5 socket in a micro-ATX layout. It delivers a 14+2+1 80A DrMOS power design, four DDR5 slots supporting up to 192GB, and a 170W CPU ready for advanced AI workloads.

Best for High-End Gaming and AI Builds

The combination suits builders who want a compact board with strong VRM cooling, PCIe 5.0 graphics and storage, Wi-Fi 6E, and 2.5Gb LAN. The 128MB L3 cache on the CPU benefits cache-sensitive titles. Users needing more than four memory slots, a full-size ATX form factor, or a lower-power processor should consider other options.

PCIe 5.0 M.2 and x16 Slots Decide Fit

The motherboard provides one PCIe 5.0 x16 slot for graphics and one PCIe 5.0 M.2 2280 slot for the fastest SSDs. Two additional M.2 sockets run at PCIe 4.0 speeds. If your GPU or primary drive requires PCIe 5.0 bandwidth in a micro-ATX chassis, this board meets that requirement; otherwise a B850 board without 5.0 M.2 may suffice.

Highlights

  • Stable power for heavy workloads
  • 14+2+1 80A DrMOS stages with 8-layer PCB
  • One PCIe 5.0 M.2 plus two PCIe 4.0 M.2 slots with large heatsink
  • Wi-Fi 6E and 2.5Gb LAN plus rear USB 20Gbps Type-C and front USB 10Gbps Type-C
  • 16-core Ryzen 9 9950X3D with 128MB L3 cache and Radeon graphics

Questions about this item

Will the Ryzen 9 9950X3D fit in a standard AM5 cooler mounting pattern?

Yes, the CPU uses the AM5 socket which retains the same cooler mounting holes as previous AM5 and AM4 designs, so existing compatible coolers will fit.

Does the motherboard provide enough power phases for the 170W CPU without throttling?

The 14+2+1 80A DrMOS stages and 8+8 pin ProCool connectors are designed to deliver stable current for high-wattage processors like the 9950X3D.

Can I run four DDR5 modules at the rated 8000 MT/s speed?

The board supports up to 192 GB across four slots with EXPO and AEMP profiles, but maximum stable frequency with all slots populated depends on the memory kit and CPU memory controller.
