Motherboard & CPU Combo

This bundle pairs the ROG STRIX X870E-H GAMING WIFI7 motherboard with the AMD Ryzen 9 9900X3D processor. The AM5 socket board supports Ryzen 9000, 8000 and 7000 series chips. The CPU delivers 12 cores built on TSMC 4nm FinFET Granite Ridge architecture with a 120W TDP. Integrated AMD Radeon graphics provide video output without a discrete card.

Check Your Setup

Verify that your chassis accepts an ATX board measuring 12.0" x 9.6". Confirm your power supply includes dual 8-pin ProCool II connectors for the 16+2+1 power stage design. Ensure DDR5 memory kits are on the motherboard QVL for speeds up to 8000 MT/s. Check that your CPU cooler clears the large VRM heatsinks and integrated I/O cover.

What the Extras Deliver

Two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots each include substantial heatsinks for sustained throughput. WiFi 7 (802.11be) and Realtek 5Gb Ethernet handle high-bandwidth networking. Rear I/O provides two USB4 40Gbps Type-C ports, four USB 10Gbps ports, six USB 5Gbps ports and two USB 2.0 ports. ASUS AI Advisor, AI Cache Boost, AI Networking II and AEMP simplify tuning.

Questions about this item

What comes in the combo box and what must I source separately?

The combo includes the ROG STRIX X870E-H GAMING WIFI7 motherboard and the Ryzen 9 9900X3D processor. You will need to buy DDR5 memory modules, storage drives, a graphics card, a CPU cooler, a power supply and a case to complete the build.

How do I choose between the four M.2 slots when adding storage?

Two slots run at PCIe 5.0 speeds and two at PCIe 4.0 speeds, all with substantial cooling. Install your fastest drive in a PCIe 5.0 slot for maximum throughput; use the PCIe 4.0 slots for additional capacity.

What does the 120W TDP of the 9900X3D mean for my cooling choice?

The 120W rating indicates the sustained heat the cooler must dissipate. Select an air cooler or AIO rated for at least 120W, and connect it to the 4-pin CPU or AIO Pump header on the board.
