Corsair RM1000e 1000W Power Supply - LABS Test Report

Duration: 03:41

The Corsair RM1000e is a fully modular ATX 3.1 power supply which is advertised as Cybenetics Gold, but has actually achieved Cybenetics Platinum efficiency. It comes with a single hybrid fan mode and a 7 year warranty. This warranty is shorter than average for this tier, but hopefully Corsair's strong reputation for reliability will be enough to make up for it.

Overall, this performs quite similarly to the Corsair RM1000x (or the Corsair RM1000x SHIFT), while being a slight step down. The RM1000e has a smaller fan, doesn't support manual fan override, and has marginally worse overall performance across the testing.

Note that there is also a 2023 version (RPS0179) of the RM1000e which is only advertised to be compliant with ATX 3.0. While there are likely many similarities between these two models, the model tested and displayed on this page is the 2025 version (RPS0217).
