Combo for AM5 builds

This bundle pairs the ASUS TUF GAMING X870E-PLUS WIFI7 motherboard with the AMD Ryzen 9 9900X processor. The CPU delivers 12 cores and 24 threads on the Zen 5 architecture with a 5.6 GHz maximum boost frequency. The board uses the AMD X870E chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series processors. It targets enthusiasts who want a high-core-count platform with modern connectivity.

Sustained power delivery

The motherboard employs 16+2+1 80A power stages on an 8-layer PCB with 8+8 pin ProCool connectors, alloy chokes and durable capacitors. This design aims to maintain stable voltage for the 9900X during prolonged multi-threaded workloads. Enlarged VRM, M.2 and PCH heatsinks work with hybrid fan headers and Fan Xpert 4 plus AI Cooling II to manage thermals over extended sessions.

Interface practical limits

The platform provides one PCIe 5.0 x16 slot for graphics with Ryzen 9000 and 7000 CPUs, while Ryzen 8000 CPUs operate the slot at PCIe 4.0 x16. Two M.2 slots support PCIe 5.0 x4 and two support PCIe 4.0 x4, with Key M 2280, 2242, 2260 and 22110 form factors. Rear I/O includes two USB4 40Gbps Type-C ports, a front USB 20Gbps Type-C header with 30W power delivery, Realtek 2.5Gbps Ethernet and Wi-Fi 7 (802.11 be).

Highlights

  • 12 cores and 24 threads for heavy multitasking with Zen 5 architecture

Questions about this item

How loud and hot does the 16+2+1 80A power-stage VRM get when the Ryzen 9 9900X runs all day?

The enlarged VRM heatsink, alloy chokes and 8-layer PCB are designed to keep the 16+2+1 80A power stages cool and quiet under sustained load, while AI Cooling II adjusts fan curves automatically.

Which DDR5 memory kit do I need to have on hand before this combo will post?

You need a DDR5 un-buffered DIMM kit up to 256 GB across the four 288-pin slots; the board supports speeds up to 8000+ MT/s via EXPO or AEMP profiles.

Will my existing PCIe 4.0 graphics card and SATA SSDs work at full speed in the PCIe 5.0 x16 slot and the four SATA 6Gb/s ports?

Yes — the PCIe 5.0 x16 slot is backward compatible with PCIe 4.0 GPUs at x16 speed, and all four SATA ports deliver 6 Gb/s regardless of the CPU generation installed.
