> 3 dayBroken right out of the box, tested it with known good parts and got nothing. Will likely never buy another Corsair cooler...

12-06-2025Been using it for 4 months now without issues. Its super quiet and youd never know it was there. The modular aspect really keeps the case looking clean by only using the plugs you need.

> 3 dayI’ll admit I suffered a brief episode of shock and awe when I opened these power supplies. I was sure I had selected the wrong thing. My computers are all-in-one. touch-screens and there is no way something like this would fit inside them.

> 3 dayNeeded one cable for my Mobo, an 8 pin and a 4 pin for the CPU, there was no 4 pin available with this unit. I have a Seasonic modular cable set which had one, but I could not plug it in because the pins were reversed. Upper left on the socket was not upper left on the cable.

> 3 dayBought this as an upgrade, returned as it would not power my 8TB HDD. Could power my 1TB, but not the 8TB.

> 3 dayLove the psu. More than enough for a simple build. Modular design enables you to put exactly what cables you need, making cable management MUCH easier and cleaner.

> 3 dayIts a nice little power supply. Its gold rate and it has like a 10 year warranty from a good company. There isnt much to dislike about it. You could probably take a star off because the cables are plastic-y and the powersupply doesnt match or something dumb. But at sale prices this thing is a very good value and works really well. I had no problems installing it into a Ryzen 7 setup to replace a 10 year old Corsair psu. They must be rebranding only quality stuff since the last one lasted through multiple hardware refreshes. Theres not a lot to say. It works and it seems pretty good.
