Corsair RM650e (650W/80+ Gold/Fully Modular/ATX 3.1/Native 12V-2x6) Review

If you're shopping for a 650W 80 PLUS Gold PSU with native ATX 3.1 and a 12V-2x6 connector, the Corsair RM650e is the budget-friendly entry in Corsair's e-series lineup.

We'd point most mid-range builders at it if the case is short on space, since the 140mm chassis is compact and Zero-RPM keeps it silent at idle. It skips sleeved cables and only gives you one native 12V-2x6, so step up to the RM650x if you want the nicer cosmetics.

Fit and Noise

At 650W this is aimed at RTX 4060 Ti/4070-class builds rather than anything pulling serious multi-GPU power. The 120mm rifle-bearing fan is inaudible under light load thanks to Zero-RPM, and the 140mm length fits in nearly any mid-tower.

Versus the RM650x

The RM650e trades the RM650x's sleeved cables and slightly tighter voltage regulation for a lower price while keeping the same Gold efficiency and 7-year warranty tier, so it's the pick if you don't care about cable aesthetics.
