Corsair engineering and quality controlEvery 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, because you need confidence and reliability regardless of your build budget. |
Ample connectors and long cablesLong cables make CX Series suitable for installation even in full-height tower cases, and the generous cable count allows you to power multiple components and storage devices. |
Large-diameter, thermally controlled fanOnce you’ve installed a PSU, you shouldn’t have to think about it. Employing a thermally controlled fan makes the CX Series virtually silent at idle, and the large diameter reduces noise even when you’re pushing your system hard. |

Overview:
A well priced and well performing power supply for prebuilts, office computers or lower power draw gaming PCs. The horrors of the Corsair CX (GREEN) models aren't to be confused as this is a well rated unit with 80+ Bronze efficiency.
I needed this for a R3 1200 | GTX 1050 system, with some headroom for a small upgrade; a higher end system would be better suited with a higher wattage unit in order to not stress the PSU and keep within the highest point of the 80+ specification - efficiency rating.
Advantages:
£40, going budget doesn't always mean a huge loss of quality or features
80+ Bronze Rated
Simple, not industrial and not 'gamery' aesthetic with a well fitting label.
Fan noise doesn't stand out from either my Corsair AF 120 (Quiet Editions) or my AMD Ryzen Wraith Stealth cooler.
Disadvantages / Desired improvements:
One feature you do miss out on is modular cables (At least for the unit I got), and since the cables are wrapped and have some 'heft' to them cable management isn't as much of a breeze as with modular units.
Whilst a low wattage unit, which also runs "cool" to "luke warm" from idle to full load; there is no ventilation on the front of the PSU - the side that faces inside your case. Again, this seems like a minor flaw due to the small amount of power it will put out, but if I was running my computer under load 24/7 as a, say, budget home server - I would get slightly uncomfortable about any possible hotspots.
Though not exactly a disadvantage; I've only had this for a couple of months, it may fail on me tomorrow as it is my first time using this specific line-up, so do take what I say with a grain of salt as your results may vary.
Bought the modular, 650W version of this power supply to replace a defunct 'be quiet!' supply that had given several years faultless service, before expiring just before New Year.
Having read the reviews, I was fairly confident that the Corsair supply would fit my needs well enough. And it does, sort of.
It's well enough made, with a suitably weighty feel to it. The modular supply has 5 ports on it for your 'extra' components' needs, along with a 24 and 8 pin fixed lead for the motherboard itself - these fixed leads are sheathed, and are neat, and long, enough.
My major issue with this supply is the lack of flexibility one might assume a modular supply would give a system builder.
In the box there are 5 leads, one for each port available on the side of the supply.
Two of the leads are supplementary power leads for PCI cards that might need them (I don't have any, as I'm not running power hungry graphics on this system), so they have a genuine benefit for anyone with, say, high powered graphics cards etc.
The other 3 leads offer either SATA, or legacy, power connectors. One lead has 3 full-sized legacy connectors and a smaller FD connector. Another has two SATA power connectors, and the last has 4 SATA power connectors.
The leads are of a reasonable length, but no more - I think you'd struggle to reach from one corner to an opposite corner in a Full tower, though the cables will reach across a Mid sized tower, such as mine. So the length you'd think would be adequate?
Well, yes, and no! If the SATA power connectors didn't need twisting around through 180 degrees to fit the hard drives, everything would be fine. But in my case, with the power supply at the top rear, running to each of the hard drives in turn meant the cable had to twist through a full 360 degrees at each connector (180 to fit, then another 180 to continue it's journey downwards)! This results in the useful cable length being shortened considerably, to the point where I couldn't power my (3) hard drives and Blu-Ray player from this single cable.
The legacy power lead is again too short, and not populated with enough connectors. Leading to a veritable mess of Black, Red and Yellow cables strung between various points in the case (two 120mm cooling fans, a USB 3 PCI card and legacy DVD Writer).
So my issue is this, and the reason for loss of stars. There is no flexibility afforded by the leads and connectors on offer, the leads are only just adequate, if your components happen to facing the 'right' way - which would be non-standard in my book. Buying the modular system has been a complete waste of money, as I've ended up re-purposing leads from my old power supply to make-good the inadequacies of this one.
What should have been a five-minute job to switch out power supplies, turned into a couple of hours of chopping up old leads, soldering, cable-tying and heat-shrinking to make good the failings of this supply!
On the plus side - it does actually work after all that!
The cables are black sleeved as you can see in the photo which is great for maintaining aesthetics, although I'm not sure as to why corsair wouldn't advertise this on the amazon listing and instead show ugly ketchup and mustard cables.
450w is enough for most (definitely not all) budget 1st 2nd and 3 gen ryzen 3 and 5 builds with graphics cards under the GTX 1660 super in terms of power draw (above this and you may want to consider more wattage or simply better quality with the CX/TM lineup). Always check your total system power draw with a service like PC part picker before building. Edit: on the amd side RX 570 is ideally the highest power drawing card you want to go with , an RX 580 should be gone but I wouldn't reccomend it and neither does AMD.
Overall for the sale price of £23 that I paid this is a shockingly good deal. Time will tell how it holds up.
