Combo for AI and high-end gaming

This bundle pairs an ASUS ROG Crosshair X870E Extreme motherboard with an AMD Ryzen 9 9950X3D processor. The platform targets builders who want a ready-made foundation for advanced AI workloads and competitive gaming. The AM5 socket supports Ryzen 9000, 8000 and 7000 series CPUs. The chip delivers 128MB L3 cache and integrated Radeon graphics.

E-ATX board with extensive M.2 and LAN

The E-ATX motherboard requires a matching case and a DDR5 kit up to 256GB across four 288-pin slots. It provides three onboard PCIe 5.0 M.2 slots plus two PCIe 4.0 slots via a Q-DIMM.2 add-in card, all with substantial heatsinks. Networking includes 5G and 10G Ethernet plus Wi-Fi 7. A 5-inch LCD and USB4 Type-C sit on the rear I/O.

Suits AI developers and enthusiast overclockers

This combo suits users who need maximum core count, large cache and robust power delivery for local AI inference or heavy multitasking. The 20+2+2 110A power stages and AI overclocking tools cater to manual tuning. Builders on a strict budget or using smaller cases should consider a less feature-dense platform.

Questions about this item

Will the 170 W CPU hit the VRM thermal limit before the 20+2+2 power stages saturate?

The board uses 20+2+2 power stages rated at 110 A each with massive heatsinks, U-shaped heatpipes and high-conductivity thermal pads, so the VRM thermal capacity is built to handle the 170 W Ryzen 9 9950X3D under sustained load.

How loud and hot does the VRM area get when the 170 W processor runs all day?

Large heatsinks integrated with the I/O cover, dual U-shaped heatpipes and thermal pads spread heat from the 20+2+2 power stages, while AI Cooling II adjusts fan curves to keep noise and temperature in check during extended sessions.

Do I already need DDR5 memory and an AM5 cooler for this combo to work?

Yes — the board has four 288-pin DDR5 slots supporting up to 256 GB dual-channel, and the AM5 socket requires a compatible cooler; neither DDR5 modules nor a cooler are included in the combo.
