model TUF GAMING X870-PRO WIFI7 W NEO

+CPU + Ryzen 9 9900X3D

  • Robust 16+2+1 80A power delivery for stable overclocking
  • Four M.2 slots with PCIe 5.0 and 4.0 support for fast storage expansion
  • 128MB L3 cache on Ryzen 9 9900X3D for high gaming performance
  • WiFi7 and 5Gb Ethernet for low-latency networking
  • DDR5 memory up to 256GB with EXPO and AEMP profiles

Combo foundation

This bundle pairs the ASUS TUF GAMING X870-PRO WIFI7 W NEO motherboard with the AMD Ryzen 9 9900X3D processor. The board uses the AMD X870 chipset and AM5 socket, supporting Ryzen 9000, 8000 and 7000 series CPUs. It delivers a 16+2+1 80A power stage design on an 8-layer PCB with dual 8-pin ProCool connectors. The CPU brings 128MB L3 cache, 12MB L2 cache and integrated Radeon graphics at a 120W TDP.

Who it fits

Builders who want a single validated kit for high-core-count gaming and AI workloads will benefit from the pre-matched components. The four DDR5 slots support up to 256GB with EXPO, XMP and AEMP profiles, plus ECC capability. Four M.2 sockets provide PCIe 5.0 x4 and 4.0 x4 connectivity, while USB4 at 40Gbps and 20Gbps USB-C with 30W Power Delivery handle modern peripherals. Users needing more than two SATA ports or legacy PCI slots should consider other platforms.

Capacity ceiling

The 256GB memory limit and dual-channel architecture give ample headroom for large datasets and multitasking. PCIe 5.0 x16 and two PCIe 4.0 x16 slots accommodate current and next-generation GPUs and add-in cards. The 5Gb Ethernet and WiFi7 interfaces sustain high-throughput network traffic. Storage expansion stops at four M.2 devices and two SATA 6Gb/s drives, so arrays beyond six volumes require external enclosures.

Highlights

  • Robust 16+2+1 80A power delivery for stable overclocking
  • Four M.2 slots with PCIe 5.0 and 4.0 support for fast storage expansion
  • 128MB L3 cache on Ryzen 9 9900X3D for high gaming performance
  • WiFi7 and 5Gb Ethernet for low-latency networking
  • DDR5 memory up to 256GB with EXPO and AEMP profiles

Questions about this item

What DDR5 memory kit do I need to populate the four 288-pin slots on this motherboard?

The board accepts up to 256 GB of DDR5 across four slots in dual-channel mode and supports AMD EXPO, Intel XMP and ASUS AEMP profiles for automatic timing configuration.

Will my existing PCIe 4.0 graphics card and M.2 drives run at full speed in the PCIe 5.0 x16 slot and the four M.2 sockets?

Yes, the PCIe 5.0 x16 slot and the four M.2 sockets are backward compatible, so PCIe 4.0 GPUs and drives operate at their rated speeds without bottlenecks.

How can I confirm the 128 MB L3 cache on the Ryzen 9 9900X3D is active after assembly?

Open Task Manager or a hardware monitor such as CPU-Z; the L3 cache field should read 128 MB, verifying the 3D V-Cache is recognised and enabled.
