+CPU + Ryzen 9 9900X3D

  • Stable power delivery with 16+2+1 80A power stages
  • 128MB L3 cache accelerates gaming and heavy workloads
  • Wi-Fi 7 and 2.5Gbps Ethernet for ultrafast networking
  • Two PCIe 5.0 M.2 slots enable high-speed storage
  • DDR5 up to 8000+MT/s with AEMP support

Ready for Advanced AI PC

This combo pairs the ASUS TUF GAMING X870E-PLUS WIFI7 motherboard with the Ryzen 9 9900X3D processor. The board uses the AMD X870E chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. It targets builders who need high core counts and large cache for AI workloads and gaming.

Installation notes

The ATX board fits standard chassis and uses 8+8 pin ProCool connectors for clear power routing. Four 288-pin DDR5 slots accept up to 256GB of memory with AEMP and EXPO profiles for simpler tuning. Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots share bandwidth with the CPU, so populate M.2_1 first to avoid lane conflicts. Rear USB4 40Gbps Type-C and front USB 20Gbps Type-C with 30W PD require correct header alignment.

Sustained load behaviour

The 16+2+1 80A power stages on an 8-layer PCB deliver stable current to the 120W Zen 5 CPU with 128MB L3 cache. Enlarged VRM, M.2 and PCH heatsinks combine with Fan Xpert 4 and AI Cooling II to manage thermals during long compile or inference runs. Realtek 2.5Gb Ethernet and Wi-Fi 7 maintain consistent throughput when transferring large datasets.

Highlights

  • Stable power delivery with 16+2+1 80A power stages
  • 128MB L3 cache accelerates gaming and heavy workloads
  • Wi-Fi 7 and 2.5Gbps Ethernet for ultrafast networking
  • Two PCIe 5.0 M.2 slots enable high-speed storage
  • DDR5 up to 8000+MT/s with AEMP support

Questions about this item

How do I confirm the 16+2+1 80A power stages and AI Overclocking are active after building with the Ryzen 9 9900X3D?

Enter the UEFI and verify the 16+2+1 80A power-stage count is shown on the hardware monitor page; enable AI Overclocking in the AI Tweaker section and watch the AI Cooling II fan-curve adjust automatically during a stress test.

What comes in the combo box and which DDR5 memory must I buy separately?

The combo includes the TUF GAMING X870E-PLUS WIFI7 motherboard and the Ryzen 9 9900X3D processor; you must purchase DDR5 DIMMs separately — the board has four 288-pin slots supporting up to 256 GB dual-channel at 8000+ MT/s with EXPO and AEMP profiles.

Which M.2 slot should I choose for a PCIe 5.0 x4 drive versus a PCIe 4.0 drive on this X870E board?

Use M.2_1 or M.2_2 (Key M, 2280) for PCIe 5.0 x4 drives with Ryzen 9000 or 7000 series CPUs; the remaining two M.2 slots operate at PCIe 4.0 x4 and accept 2242/2260/2280/22110 form factors.
