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. And, when it's 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 and connect to your new fully-modular Corsair power supply.
Fantastic Power Supply7/8/2012
The Corsair AX850 Power Supply unit I purchased from buy.com was very easy to install on my new computer build. Plenty of cables to do what is needed. Fan only runs when it gets enouph of a load that it needs to cool itself off. I am very happy with my purchase. My new computer build includes the following: p9x79 Pro Motherboard (buy.com) Intel Core i7-3820 Processor 24 GB Corsair Vengeance (6 x 4GB) 1600 Memory Corsair 650D Mid Tower Case Corsair H100 Liquid Cooling (buy.com) Corsair M4 128GB SATA III SSD (Just ordered from buy.com) Until the SSD arrives, I am using a SATA hard drive.
