Installation made Easy FASTER INSTALLATION AND BETTER-LOOKING BUILDS The modular cabling system lets you use only the cables you need.

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 PCIe 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. Built to Last RELIABLE AND COMPATIBLE CX Series Modular is built and tested to strict standards for trouble-free installation and smooth operation. The matte black finish, black-sleeved cables and black connectors help give your system a restrained, high-tech look.

The same care that goes into the design and testing of their renowned high-power enthusiast power supplies also goes into the CX Series Modular, because you need confidence and reliability regardless of your build budget.
