High Power & Incredible Efficiency In Corsair's Quietest PSUs Ever
Corsair's HXi Series Power Supplies give you extremely tight voltage control, virtually silent operation, and a fully modular cable set. With all Japanese 105° C capacitors, they're a great choice for high performance PCs where reliability is essential. 80 PLUS Platinum efficiency reduces operating cost and excess heat, and together with Zero RPM Fan Mode technology, gives you virtually silent operation.
With Corsair Link Digital support, you can monitor power supply performance, toggle single rail or multi rail mode, and control fan speed directly from your desktop. And, the fully modular, low profile cable set makes builds and upgrades easy, with clean, great-looking results.
Quiet, Efficient Operation
80 PLUS Platinum efficiency and Zero RPM Fan Mode work at low to medium loads so the fan doesn't spin. When you do push the HXi hard, the thermally controlled fan spins as slowly as possible.
But that's not all. It's quieter than most PSUs when the fan's not spinning, too. The HXi is built with capacitors and other internal components specially selected to reduce coil whine and other noises.
Corsair Link Digital for advanced monitoring and control
Connect the included cable to a motherboard USB header and download the free Corsair Link Dashboard application for Windows and you can monitor performance and efficiency, toggle single rail or multi rail mode, and control fan speed directly from your desktop.
The fully modular, low-profile cable set allows for quick and easy installation and great-looking builds. The fan self-test switch lets you quickly confirm operation before you even attach cables to your motherboard.
