This new version of the EPU is able to detect current PC loadings in real time and automatically moderate the power supply for complete system level power savings. With automatic power management for components, the EPU-Six Engine provides the most appropriate power usage via intelligent acceleration and overclocking – helping users achieve the ultimate in energy savings.

75% of the time, the PC is utilized in everyday computing tasks that don’t require the maximum amount of power. However, the components will continue consuming power unconsciously – resulting in power loss. This power loss will occur in day to day operations and is invisible – adding up quickly in the long run. It is thus vital for users to be aware of this "hidden" power loss.

The ASUS EPU-Six Engine guards against this power loss through intelligent and automatic monitoring and moderation of the power supply – lowering heat and providing a exceptional 96% power efficiency (the higher the power efficiency, the more energy that is saved).

With the EPU-Six Engine, savings of up to almost a household’s monthly electrical bill can be attained! It is able to achieve this by focusing on six major components: namely the CPU, VGA card, memory, chipset, Hard drives and CPU cooler/system fan.

Equipped with a database containing all of the Intel CPU profiles, the EPU-Six Engine intelligently identifies and selects the correct CPU profile, and calibrates the best possible settings – ensuring the best possible power management. In terms of the Chipset and Memory, the EPU-Six Engine provides up to 96% enhanced power efficiency – thereby improving thermal capabilities, which leads to better component quality and lifespans. This in turn provides users with a more stable system and higher O.C capabilities.

VGA graphics cards normally utilize more power than they should. A good example would be when the user is surfing on the Internet. The VGA card would be utilizing its full power unconsciously without the EPU-Six Engine.

Supporting the most popular and latest graphics cards, the EPU-Six Engine is able to automatically detect system loading, and adjust the VGA card’s voltage and frequency – saving up to 37% VGA power during everyday computing. The EPU-Six Engine also cleverly monitors the Harddisk and Fans – reducing power wastage spent when there is no data access during idle modes.
