ASUS ROG Crosshair X870E Extreme+ Combo

This bundle pairs the flagship ROG Crosshair X870E Extreme+ motherboard with an AMD Ryzen 7 9700X processor in a single package. The E-ATX board uses the AMD X870E chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. It targets enthusiasts building high-end AI-ready desktops or extreme gaming rigs. Overclocking headroom is provided by a 20+2+2 phase power stage design rated at 110A per stage.

Suited for maximum connectivity and AI workloads

The platform delivers dual 5Gb and 10Gb Ethernet, Wi-Fi 7, USB4 Type-C and a built-in five-inch LCD dashboard. Five M.2 slots are available, three running at PCIe 5.0 speeds and two at PCIe 4.0 via the Q-DIMM.2 card. Builders needing a smaller micro-ATX board or a lower-cost entry point should consider other AM5 models. The 256GB DDR5 limit across four slots also means extreme memory capacity seekers must verify requirements.

20+2+2 power stages at 110A each

The voltage regulator module uses twenty 110A stages for Vcore, plus two 110A stages each for VCCGT and VCCSA, all fed by ProCool II connectors. This specification determines whether the board can sustain heavy all-core loads on Ryzen 9000 series processors without throttling. If the intended workload demands continuous high current, this phase count and current rating are the decisive figures.

Questions about this item

Does the combo box include the Ryzen 7 9700X processor or is it sold separately?

The bundle ships with the AMD Ryzen 7 9700X already paired with the ROG Crosshair X870E Extreme motherboard so the CPU is not a separate purchase.

Which DDR5 speed tier matches the 8200 MT/s OC figure shown for the 9000 series CPU?

The 8200+ MT/s overclock rating applies when the included Ryzen 9000 series processor is installed and memory is tuned accordingly.

What does the 20+2+2 power-stage design mean for the 8-core 9700X under load?

The 20(110A)+2(110A)+2 stages with ProCool II connectors deliver clean current to the 8-core CPU during heavy gaming or AI workloads.
