The short version
Corsair's 650 W RMe model is a fully modular ATX 3.1 power supply rated Cybenetics Gold for efficiency and A++ for noise, in a short 140 mm casing. It carries a native 12V-2x6 cable, a cable that splits a 12V-2x6 socket to two 8-pin plugs, one 8-pin PCIe cable and a Zero RPM mode. It suits mid-range gaming PCs. The warranty runs seven years rather than the ten offered on Corsair's RMx line.

Common questions
Will the Corsair RM650e fit a small ATX case?
Corsair lists 140 x 150 x 86 mm dimensions, so it is a standard 140 mm long unit that fits most ATX cases with a shroud.
Can the RM650e power two 8-pin GPU sockets?
Yes. It includes one 8-pin PCIe cable and a 12V-2x6 to dual 8-pin cable, and Corsair also bundles a native 12V-2x6 cable for cards that use it.
