Corsair RMe Series RM750e

7.2/10verdict: good, not the best

The RM750e is for people building a single-GPU desktop who want a fully modular ATX 3.1 power supply with a native 12V-2x6 cable. It suits builders who value a quiet fan that stays off at idle and a 7-year warranty. It is a weaker fit for machines that idle around the clock, where owners report poor low-load efficiency.
