The Corsair power supplies have been at the forefront of PSU design for many years now, being the first manufacturer to allow your system to monitor your PSU's power draw and other statistics using Corsair link is only just being emulated by other manufacturers.

Bought this to replace a PSU that failed. Runs quiet ( or at least quieter than my GPU, which is all I ever hear ). Fully modular cabling made it easier to retrofit by letting me replace the cables before swapping out the actual PSU unit.

It's a great power supply when you're looking for a 1kW. I wasn't a huge fan of the GPU cable as it has 2 end connectors rather than just allowing me to only use the 1 as in my setup, so the look is not so good, but it is easy to get mod cables anyway so I will be doing this.

When Corsair launched the RMx-series we only received power supplies of 750 watt or higher. However now we gotten our hands on the 550 and 650 watt models. Note that the price difference is not that much, especially considering the step up in price when looking at an RM850x or an RM1000x.

Constant power, no "sparks"
