Good looks

The matte black finish, black-sleeved cables, and black connectors help give your system a restrained, high-tech look.

Reliable and compatible

CX Series is built and tested to strict standards for trouble-free installation and smooth operation.

Corsair engineering and quality control

Every Corsair power supply is designed by our California engineering team and built to our exact specifications. The same care that goes into the design and testing of our renowned high-power enthusiast power supplies also goes into the CX Series, because you need confidence and reliability regardless of your build budget.

Ample connectors and long cables

Long cables make CX Series suitable for installation even in full-height tower cases, and the generous cable count allows you to power multiple components and storage devices.

Large-diameter, thermally controlled fan

Once you've installed a PSU, you shouldn't have to think about it. Employing a thermally controlled fan makes the CX Series virtually silent at idle, and the large diameter reduces noise even when you're pushing your system hard.
