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.

CX Modular 600W wins Guru3D Recommended award!

The CX600M has budget written all over it, budget in this case however isn't a negative thing. After testing it quite extensively we really do get the feeling that it is a good power supply. Next to that for the money it's rather good looking with its all dark cables and connectors as well. We did not notice any issues in terms of voltage dips or weirdness, overall it simply is a good PSU for the money. At 60 bucks this is hard to beat. It's of course a crowded market with quality and efficiency levels being bumped up with each year that passes. But this PSU definitely is a winner in terms of price versus quality versus features versus looks. The one remark really are just two PCie graphics connectors. But that's all I can think of. It doesn't cost a small fortune, and you get three years warranty. Yup - Recommended by

CX600 Modular wins "Great Value" award from TechPowerUp!

“To wrap up, the CX600M offers good performance, modular cables that are flat and stealth, and is backed up by Corsair's excellent support. The CX600M is, if you can live with only having two PCIe connectors, a very good deal, as clearly shown on our performance-per-dollar graph. Based on the latter, I give to this unit our budget award.”

"Corsair ably demonstrates that you don't need to spend a fortune on your next PSU upgrade, and we'd be inclined to put the CX600M on a pretty short list for your next purchase."
