Ready for Advanced AI PCs

This bundle pairs an ASUS ROG STRIX X870-A GAMING WIFI S motherboard with an AMD Ryzen 9 9950X3D processor. The board uses the AMD X870 chipset and AM5 socket to support Ryzen 7000, 8000 and 9000 series CPUs. The included 9950X3D brings 128 MB of L3 cache and a 170 W TDP built on TSMC 4 nm FinFET Granite Ridge architecture. Integrated AMD Radeon graphics provide baseline display output.

Suits AI developers and high-core-count workloads

Builders who need maximum multi-threaded performance and AI-ready connectivity will benefit from the 16+2+2 power solution rated at 90 A per stage and four M.2 slots with substantial cooling. The package is less suited for compact chassis or budget-focused builds that cannot use the full power delivery, PCIe 5.0 storage bandwidth or WiFi 7 networking.

Bundled AI features and storage flexibility

ASUS-exclusive AI Overclocking, AI Cooling II, AI Networking and AEMP automate tuning for DDR5 memory and system thermals. ROG Strix technologies including Dynamic OC Switcher, Core Flex, Asynchronous Clock and PBO Enhancement extend manual control. Two PCIe 5.0 and two PCIe 4.0 M.2 slots, plus USB4 and WiFi 7, remove bottlenecks for large datasets and high-speed peripherals.

Questions about this item

What cooler and power supply do I need for the included 170W Ryzen 9 9950X3D CPU?

You need an AM5-compatible cooler rated for at least 170W TDP and a power supply with dual 8-pin EPS connectors to feed the motherboard 16+2+2 90A power stages.

Will my PCIe 4.0 graphics card and M.2 drives still run at full speed on this X870 board?

Yes, the board provides two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots, so existing 4.0 devices operate at their native bandwidth.

How can I confirm the 128MB L3 cache and AI features are active after assembly?

Check the BIOS main screen for the 128MB L3 cache size, then enable AI Overclocking, AI Cooling II and AEMP in the AI Intelligent Control section to verify they are functioning.
