Corsair RM850e ATX 3.1 (2025) PSU Review

These new supplies are fairly compact in size, measuring 160x150x86 mm. The quality of the paint is good and the styling is neutral in colour with all the logos and badges in silver/white on the sides of the chassis.

The grille at the top of the unit is heavily stylised with a Y logo shape to allow for airflow. As I mentioned in the last video its not the best possible venting for airflow in my opinion but it didn't seem to greatly impact the 1000W unit when we tested it.

The modular bay is split into a traditional Corsair way across two vertical rows, separated into panels.

The power side is home to the power connector and power switch and the vented panel which aids with airflow from the unit inside.

This unit is able to deliver 70.8A across the primary single +12V rail. Both +3.3V and +5V minor rails can deliver 20A.
