Ready for advanced AI PCs

This motherboard and CPU combo pairs the ROG STRIX X870E-H GAMING WIFI7 with the AMD Ryzen 7 9800X3D processor. The board uses the AMD X870E chipset and AM5 socket, supporting Ryzen 9000, 8000 and 7000 series desktop processors. It targets builders who want a high-performance platform for demanding AI applications and gaming.

Build integration and expansion

The ATX board measures 12.0 x 9.6 inches and requires a 24-pin main power connector plus two 8-pin +12V CPU power connectors. It provides four DDR5 slots supporting up to 256GB at 8000+ MT/s, one PCIe 5.0 x16 slot for graphics, two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots. Rear I/O includes two USB4 40Gbps ports, four USB 10Gbps ports, six USB 5Gbps ports and two USB 2.0 ports.

Bundled accessories and software impact

The package delivers WiFi 7 (802.11be) and Realtek 5Gb Ethernet for high-speed networking. Onboard audio supports 7.1 channels. ASUS AI Advisor, AI Cache Boost, AI Networking II and AEMP simplify setup and optimise performance. Massive heatsinks with an integrated I/O cover and high-conductivity thermal pad cool the power stages and all four M.2 slots. The CPU earned a CES 2025 Innovation Award Honoree for its 2nd-gen 3D V-Cache technology.

Questions about this item

How long can the 16+2+1 power stages rated at 80A sustain full CPU load before thermal throttling?

The 16+2+1 power solution uses dual ProCool II connectors, alloy chokes and durable capacitors to support multi-core processors; massive heatsinks with an integrated I/O cover and a high-conductivity thermal pad keep the VRM cool during sustained workloads.

What are the fan-header options and typical noise levels when the system runs all day?

The board provides one 4-pin CPU fan header, one CPU OPT header, one AIO pump header and five chassis fan headers, all controllable via UEFI or ASUS Fan Xpert for quiet 24/7 operation.

Which DDR5 memory kit and cooler mounting hardware must I already own for this combo to work?

You need a DDR5 kit up to 8000+ MT/s (OC) and an AM5-compatible cooler; the motherboard includes four 288-pin slots supporting 256 GB maximum in dual-channel non-ECC configuration.
