Corsair recently sent us some new power supplies to review and today we take a look at the Corsair RM1000e, a new gold rated ATX v3.1 PSU. This is a fully modular unit with native 12v-2×6 connectors to power the latest graphics cards. This is a supply slotting in below their higher end Corsair models and they come with a 7 year warranty. Let's take a closer look.

Corsair are releasing three power supplies in this range, a 750w, 850w and 1000W unit. They sent us several PSUs for review, but today we look at the RM1000e flagship model.

UK prices from Corsair directly indicate that only £10 price difference exists between the 750 watt and 850 watt models, while the 1000W model is £35 more expensive. As we previously mentioned, all models have a 7 year warranty in place which falls some way from the leading 12 years on some of the platinum models we have reviewed lately. This is one of the tradeoffs when you move down a companies product stack.
