Summary: Being modular is fantastic for a clean setup. It seems to generate plenty of stable power. Here's where it fails: it is VERY loud at load. At idle or just messing around the internet this thing is quiet, but as soon as you start up a game it will be extremely loud! The fan is by far the loudest part of my computer, which is very annoying. I have a i5 2500k stock speed and a GTX570. If I'd known about the noise I would have gone with another psu.
