Corsair RM1000e ATX v3.1 (2025) PSU Review

The power supply is relatively compact, measuring 160x150x86 mm. The quality of the black paint is really good. The styling is colour neutral with the logos and badges all in silver/white on the sides.

The grille at the top of the unit is punched with a Y logo shape to allow for airflow. I am not sure they are maximising possible airflow, but we will check the cooling results later.

The modular bay is split in a traditional Corsair manner across two vertical rows, separated into sections.

The power side of the unit is home to the vented panel, and the power switch and connector.

This unit is able to deliver 83.3A via the +12V rail and 20A to the minor +3.3V and +5 V rails. This is enough to power any gaming GPU on the market right now.
