    I'm very happy with this PSU. Fully modular and cool under full load, even without the fan kicking in. In fact, I wonder if the fan will ever have to do some cooling ;) Integration with Corsair's Link software is a plus.

    Even with both my cards in SLI the fan doesn't seem to spin, and if it does it's inaudible! Very good PSU.

    Great quality while not being over-expensive

    I like how they have a fan test button since the fan usually rests at 0 RPM by default. No issues with the unit as expected from Corsair.

    Looks great, matches the case, came in like a velvet bag, over all great build. I have had no problems with this power supply, however I did find the cables it came with to be rather stiff and... boring. Other than that fantastic part with no problems. Did I mention it came in a velvet bag with about 300 cables?

    amazing power supply, love the Corsair Link software. even with all of the stuff that is powered through this I only manage to output 724W at maximum load.

    Exactly what you expect from a tier one unit.
