    This CORSAIR RM Series, RM750, 750 Watt, 80+ Gold Certified, Fully Modular Power Supply unit provided a nice power bump to my PC in preparation for a video card upgrade. Ive made the mistake in the past of trying to upgrade graphics before power and it aint pretty. This power supply unit is just enough extra power over my old 500 watt psu to ensure I meet the needs of the new card and it was a dream to install (less than 30 minutes from power off to power on) what with the modular cabling system meaning I dont have to fold and tuck and tie up extraneous wires all over the place. Makes the insides of the computer a lot neater and less of a dust trap to boot. This unit is also virtually silent, and I only hear the fan come on when Im knees deep in a particularly demanding game Ive had Corsair PSUs in other rigs and have never had a problem yet.

    This power supply is definitely one of the best. It’s super quiet and efficient. Plus how can you go wrong with the white cables that are included AND labeled! Installing this thing is easier than blaming your dog when you fart I kid you not. My last Rosewill psu sounded like a Boeing 747 taking off so it’s nice to finally have some quiet while my pc is on.
