Very quiet- The cables work perfectly and you only need to run the necessary ones which is nice. Be careful though - The shift intentionally has the cables on a different side, so verify with Corsair that your case will work with this specific one before ordering.

Worked on arrival.Tip, always buy psu new with extended warranty. Psu will most likely go first.

Very quiet and I love that the cables are on the side. Not compatible with some cases but should be fine with most.

ATX 3.0 supporter, fully modular, PCIE 5.0. Just delivered and used for 1 week, everything works perfectly. The PSU is quiet even in some power monster 3A games. Recommended.

This power supply was a perfect fit for my case, and was definitely the right choice for my all white build easy to know where to plug things in. And the white cables really help with the aesthetic.

Works well and all and for 100$ fully modular with many many extra cables, I don’t see myself needing to replace this ever. However I don’t know why they decided to put the outlets on the side rather than perpetuate to the outlet to outside the pc. I got a h6 flow and it made it really hard to manage the excess cables however it wasn’t a deal breaker with this case. Just had to take more time to route cables.
