Quiet and efficient
Going from an old non-modular to this unit significantly increased my efficiency and it cut noise way down too. The new cables are pretty and tidy, the fan is quiet when it does run, and coil whine is practically zero.

Solid PSU – Great purchasing
Picked this up for a new PC build and it's been running great. The installation was straightforward, and the fully modular cables definitely made things a lot cleaner inside the case. Everything powered on the first try, and it's been stable without any issue. Running a Core i7 & PNY 5060 without breaking a sweat. Also really quiet – honestly can’t hear it at all most of the time. It seems well-built and came nicely packaged too. No complaints so far. Hopefully it holds up long-term, but first impressions are all positive. Would buy again.

A Great PSU Upgrade!
I purchased a RTX 5070 Founders Edition GPU and wanted to upgrade my Corsair CX 650 M PSU as well. Moving up to the RMx Corsair series was the right move. It has better internal components, greater efficiency and a manual over-ride control for the fan. In addition, it comes with the latest power cable, perfect for my new GPU!
