80 Plus Gold certified modular PSU with a huge seven year manufacturer warranty! ** Unprecedented Power Protection** The Corsair Professional Series Gold power supply pushes the state of the art for reliable delivery of clean power under imperfect conditions. If you require mission-critical stability or you simply want one of the best power supplies available, the Professional Series Gold is for you. **A Fully Modular Cabling System** All cables detach from the power supply. During installation, this gives you the flexibility of using only the cables you need for a clean system build with optimal airflow. &, when its time to replace or upgrade your power supply, it can be removed from your system without interfering with your cabling -- the cables stay in place & connect to your new fully-modular Corsair power supply. ** Incredible Efficiency** With 90% efficiency at 50% load, the Corsair Professional Series Gold power supply runs quieter, generates minimal excess heat, & saves you money every month. Its earned the 80 Plus Gold seal of approval, your guarantee that youre making the right choice for smart, efficient power delivery. ** Ultra Low Noise
- Hybrid Silent Fan Control** The Corsair AX850s energy-efficient design allows it to operate reliably with minimal cooling, & hence very low noise levels. The AX850s Hybrid Silent Fan Control technology offers three modes of cooling, depending on the load level. This

Includes:: a fanless mode of operation (0 rpm) up to about 20% load, a quiet, low fan speed cooling mode for typical loads up to around 50% load, & a higher performance cooling mode for more demanding loads. Noise levels still remain low even when fan speeds start to climb, thanks to the use of a premium-quality 120mm San Ace fan from industry-leader, Sanyo Denki.
