Model ROG CROSSHAIR X870E EXTREME

CPU +Ryzen 7 9800X3D

  • Ready for advanced AI computing with AM5 socket support for Ryzen 9000 8000 7000 series
  • AI overclocking cooling networking and AEMP simplify setup and boost performance
  • Robust 20 plus 2 plus 2 phase 110A power stages with ProCool II connectors
  • Massive heatsinks with U shaped heatpipes and 3D VC M.2 heatsink for PCIe 5.0 slot
  • Three onboard PCIe 5.0 M.2 slots plus two PCIe 4.0 slots via Q-DIMM.2

Combo for AMD AM5 builders

This bundle pairs the ROG Crosshair X870E Extreme motherboard with a Ryzen 7 9800X3D processor, ready for high-performance gaming and workstation tasks on the AM5 platform. The board supports Ryzen 9000, 8000 and 7000 series CPUs and accepts up to 256GB of DDR5 across four 288-pin slots with AEMP and NitroPath DRAM technology.

Thermals noise and power

A 20+2+2 phase VRM uses 110A power stages, ProCool II connectors, MicroFine alloy chokes and premium metallic capacitors to deliver clean power under heavy loads. Massive heatsinks integrated with the I/O cover, two U-shaped heatpipes, high-conductivity thermal pads and a 3D vapour-chamber M.2 heatsink keep key components cool during sustained workloads.

PCIe 5.0 M.2 capacity

Three onboard PCIe 5.0 M.2 slots support 2242, 2260, 2280 and 22110 form factors, while two additional PCIe 4.0 slots are available via the Q-DIMM.2 module, all with substantial cooling. This density lets you install multiple high-speed drives without add-in cards, a decisive factor for storage-heavy builds.

Questions about this item

How do I install the Ryzen 7 9800X3D into the AM5 socket on this board, and what step is often missed?

Align the triangle marker on the CPU with the socket corner, lower it gently without pressure, then close the retention arm; the step often missed is removing the protective plastic cover from the motherboard socket before placement

What maintenance or replacement will the 5-inch LCD panel on the I/O cover need over time?

The LCD panel is a passive display driven by the board firmware; it has no user-serviceable parts and requires no scheduled replacement, only occasional cleaning with a soft dry cloth

Which thermal limit appears first on the 20+2+2 110A power stages during sustained all-core loads?

The VRM heatsink temperature rises first; the massive integrated heatsinks with two U-shaped heatpipes and high-conductivity thermal pads are designed to delay throttling under continuous 110A per stage operation
