ASUS Quiet Thermal Solution
ASUS Quiet Thermal solution makes system more stable and enhances the
overclocking capability.
ASUS EPU
The ASUS EPU utilizes innovative technology to digitally monitor and
tune the CPU power supply with improved VR responses in heavy or light
loadings. It automatically provides power for higher performance or improve
efficiency by 50% when the PC is running low intensity applications. Working
together with AI Gear 3+, this can help you attain the best possible power
efficiency and energy savings up to 80.23% to help save the environment.
See page 5-19 for details.
ASUS 3rd Generation 8-Phase Power Design
Longer Life, & Higher Efficiency!
With power efficiency so important to operating temperatures, ASUS' 3rd
generation 8-phase VRM design leads the industry with its 96% power
efficiency. High quality power components such as low RDS (on) MOSFETs
for minimum switching loss & lower temperatures, Ferrite core chokes with
lower hysteresis loss, and high quality Japanese-made conductive polymer
capacitors all add up to ensure longer component life and lower power loss
- creating more energy efficiency.
AI Nap
With AI Nap, the system can continue running at minimum power and noise
when you are temporarily away. To wake the system and return to the OS
environment, simply click the mouse or press a key. See page 5-21 for
details.
Q-Fan 2
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan
speeds according to system loading to ensure quiet, cool and efficient operation.
