Performance, Reliability, the Convenience of Modular Cabling for Basic 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.

Low noise

80 Plus Bronze certified efficiency and clever fan design allow for little or no detectable fan noise during regular operation.

Reliable and compatible

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

Compatibility

  • Auto-switching circuitry provides universal AC input from 100V – 240V
  • Supports ATX12V 2.4/2.3/2.2/2.01 and EPS12V 2.92 standards
  • Dimensions: 150mm x 86mm x 140mm

Features

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.

Good looks

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

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.

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.

    Lasted for 6 years
    Used it for 5 years with a 1070ti+ryzen 5 2600 and 1 year with a 4070+ryzen 7 5800x3d. Finally gave up yesterday. It went above my expectations for a 550w PSU.

    Reviewed in India on September 26, 2020
    Got this one because I need that much power for Ryzen 3900XT + RTX 3080.
    (My RTX 3080 will be delivered in October because we live in India)
    Another reason to get this is because of less wires, create less clutter in the case.

    Check the rest of the specs in the image.
    I don't think it comes with a Molex connector but I may be wrong since I did not check for it.

    Strangely enough, the seller sent me WhatsApp messages to ask what my configuration is.
    Now I don't want to complain about them reaching out to me to check for compatibility, it's probably for the betterment of humanity. Anyways, I thought this might be something you, the reader, would want to know.
