Power Stages

UNDENIABLY ROG STRIX

Diagonal slats, brushed aluminum, and bold RGB have become hallmarks of the ROG aesthetic, and the Strix B850-E bears all of them with pride. But for this generation, translucent diffusers line the I/O shroud and the Q-Release array, softly contrasting the metallic heatsinks nearby.

OUTSHINE THE COMPETITION

ROG Strix motherboards feature ASUS Aura technology, enabling full lighting control and a variety of presets for both onboard RGB LEDs and third-party accessories. Effects can be easily synced across compatible ROG graphics cards, monitors, keyboards, and mice to give your setup a unified look.
