Innovate. Perform. Dominate.
Created to celebrate ROG's 20th anniversary, the ROG Crosshair X870E Edition 20 combines iconic design, exclusive collectability, and flagship performance in one exceptional platform.
Equipped with robust 24+2+2 power stages, up to nine M.2 slots, and a full-copper VRM thermal solution, it delivers uncompromising stability and cooling for extreme performance.
Paired exclusively with the ROG RYUJIN 360 EDITION 20, featuring the Asetek EMMA Gen10 V3Rx pump and a high-performance cold plate crafted from 99.95% high-purity copper, designed to simultaneously cool both the CPU and critical VRM components, this ultimate combination pushes thermal performance even further.
Completing the experience is the Swivel Dual 6.67" AMOLED LCD with ASUS Infohub control, transforming the system into a synchronized showcase of performance and immersive visuals.
