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

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.

    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.

    5.0 out of 5 stars Using with a Dell Inspiron 3670 - needs a 24-pin to 8-pin adapter
    Reviewed in the United States on May 24, 2019
    Dell Inspiron 3670 i7 8th Generation are sprightly mid-range business machines that offer very good bang for buck as far as performance but, and it is a big BUT, Dell really, really don't want you to extend their use outside of business.

    My need was for a machine that would happily work Davinci Resolve video editing. I used a Geforce 6GB GPU for the video crunching, but to do so I had to add an external power supply and ditch the on-board PSU for the Dell. There are NO spare power taps on the 3670 - no supplementary power for cards or additional drives. The ATX mobo connection is also special which means you can't use the 24-pin ATX connector that comes with the Corsair.

    You must separately get a 24-pin to 8-Pin adapter to power the mobo, and then take the 6-pin CPU connector from the Corsair to the CPU socket on the mobo. This worked for me: https://www.amazon.com/gp/product/B01A210HKO and there are others available

    Then you have power to the GPU, and power for a second drive (so I could switch to an SSD plus the original HDD as a data store) plus power to a USB3 card for my external data stores..

    The new PSU sits on top of the case, and snakes in through the remaining slot access - not to everyone's taste - but it all works very happily and is almost silent. I retained the original PSU and connectors so I can reverse this out for a vanilla machine at a later date. It voids the warranty from Dell, of course, but if you cared about that then you wouldn't be here. Good luck.

    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.
