Performance, reliability, and the convenience of modular cabling for basic system upgrades CX Series Modular power supply units are an excellent choice for basic system builds and desktop PC computer upgrades, offering high reliability, low noise, and the flexibility of modular cabling.
Faster installation and better-looking builds The modular cabling system lets you use only the cables you need. You get to save space and reduce clutter for a cleaner-looking build and improved airflow.
Reliable and compatible CX Series Modular is built and tested to strict standards for trouble-free installation and smooth operation.
Low noise 80 PLUS Bronze certified efficiency and clever fan design allow for little or no detectable fan noise during regular operation.
Good looks The matte black finish, black-sleeved cables and black connectors help give your system a restrained, high-tech look.
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 Modular, because you need confidence and reliability regardless of your build budget.
Modular cabling system Since the peripheral power cables aren’t hard-wired to the power supply, you can connect only the cables you need for your exact configuration of PCI-E cards and storage devices. The rest of the cables stay in the box, and not in your PC’s case where they can add to the clutter and interfere with airflow.
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 Modular quieter at idle, and the large diameter reduces noise even when you’re pushing your system hard.
