The Asus-developed EPU is the world's first hardware-based on-demand power saving IC controller. This automatic energy saving chip utilizes an innovative power technology to digitally monitor and automatically fine-tune the CPU power supply under any loading. Real-time automatic detection of the CPU current provides total control for the best possible power efficiency; and saves up to 80.23% CPU power when the PC is running low intensity programs. Coupled with the innovative AI Gear – which features a new user interface that shows users exactly how much electricity and CO2 is being saved, the Asus EPU can provide users with up to 50% enhanced power efficiency.

Asus motherboards with the new EPU will include the P5K/ EPU and P5K SE/EPU, the new RAMPAGE FORMULA and P5E3 PREMIUM/ WiFi@n motherboards, amongst many others.
