ASUS exclusive Super Alloy Power applies special-formulated components to provide an efficient power supply for a 15% performance boost, 35°C cooler operation and 2.5 times longer lifespan. A unique dust-proof fan design dissipates heat efficiently and extends the graphic card’s lifespan by 25% (10,000 hours) through increased dust and particle resistance.
