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.
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.
- 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
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.
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.

Some background: my home-built PC case came with a 500-watt power supply and worked great until I added a third hard drive. After that, I started having reliability problems with my data storage drive, a typical rotating platter hard drive. It took me a while to figure out that I wasn't getting bad hard drives, but instead had a problem with a marginal power supply (I've got other problems too, but they aren't computer-related). Indeed, the Corsair website has a power-supply finder/calculator, and I figured out that my system needed 600-watts to be reliable. The calculator takes into account how many drives you have, as well as the fan on your video card, so if you're not sure how big of a power supply unit you need, check out the calculator. That calculator won't solve your personal life problems, but it's awful handy in picking out the right power supply unit.
Swapping this new Corsair in couldn't have been any easier. Well, actually, yeah, if someone else had done it for free, it would have been easier, but okay, this was pretty easy, even for a clumsy guy like me. If you're nervous about swapping, relax and let me walk you through it. I'll leave off the part involving the tarantula and the goat. Step 1) unplug your power cord from the back of the old power unit. 2) Unplug the power connectors from your drives, motherboard, video card fan, and case fan. 3) Get the right Phillips head screwdriver and unscrew the old power supply and don't lose the screws 4) Pull the old power supply out. Don't drop it on the motherboard as you do that. 5) Take the new included SATA power cables and plug those in to your drives. There are two cable, with three connectors each, so you can power up to 6 SATA devices. 6) Plug in your video card power cable. 7) Now place your new Corsair power supply into the case and using the screws from 3) above, secure it. 8) Plug in the SATA cables and video card cables; and 9) Plug in the motherboard power connector and case fan connector. That's it. Took me 20 minutes and I had never done it before. Your mileage may vary, batteries not included, and not applicable in California. Oh yeah, 10) plug the cord back in and flip the switch on the power supply to | . Sorry about that; should have remembered that step.
Oh, I suggest using your smartphone or a digital camera to take a photo of the motherboard before you start. Reason for that: if you happen to accidentally pull out a cable like the power switch connector to the motherboard or the HDD indicator lamp connector, it'll be easier to figure out where it goes. Just a little hint, not that I may have pulled out the power switch connector to the motherboard or anything like that. I'm too smart to have done that.
Seriously though, what's included in the box are the power supply (the motherboard and case fan connectors are hardwired in); a power cord; two SATA power cables, and peripheral cables (e.g. for a video card). If you only have three SATA device and they're not too far apart, you can get by by ony plugging in one SATA power cable but you may find it easier to use both cables if the devices are further apart.
When I started my computer up, I was shocked (no wait, bad choice of words for a power supply review) I was very happily surprised when my computer was super, super quiet. It was so quiet, I thought I had a bad power supply. But then my screen came on and man, I felt like a God, because it all worked. "I am the Man," I said to myself. Yeah, that's a mixed metaphor, but only the great writers get to use them properly.
So, if you've never swapped a power supply before and you want the opportunity to feel like a God (or a Goddess, if that's your thing), this Corsair CX series is just the thing for you. If you have swapped a power supply before, then why did you read this far into the review? I already told you it's great! Just go ahead and buy it already!
I would have given it 5 stars except for cabling issues.
The power calculators at Corsair and EVGA recommended 500-550W PSUs.
I went for 650W as that way my actual usage will be in the most efficient part of a 650W output power curve.
Pros: 12 and 5V power much closer Vs my (6 years+) CoolerMaster 650W 80 Plus PSU.
According to Speedfan: 12.03, 4.89, and 3.25 v+ volts (old PSU was dead on for 3.3V). Tolerance for Bronze 80 is +/- 10%.
Fan so far so quiet I can't hear it above my CPU and case fans, which are set to run at 65% max most of the time.
Cons: CPU power cable tricky to figure how to split the two. I only have one CPU and the Mbd has components near it so 2 together won't fit.
Molex cable too short to go to my optical drives at top of case and a video card near the bottom of the case.
(luckily, I had some molex power splitters that allowed me to extend it to the video card)
SATA cables have the connectors 'upside down' as far as I am concerned.
Due to their orientation cannot go from PSU -> top SATA drive -> lower -> lower -> lower. You'd have to twist each connector upside down.
Have to use the SATA connector closest to the PSU to connect to the farthest possible drive, then connect to the SATA drives above that one.
Due to this I had to use both SATA cables to get all 4 drives connected, instead of just the one long cable.
