While not the most efficient PSU out there, and not the cheapest either, it is still a great PSU, IMO. I have one in my game rig and my only complaint is the neopower's built in fan speed contol could be better, but I decided not to use the fan-only connector anyways and adjust my fan speeds the old fashioned way, lol. So the feature I wasn't happy with I decided wouldn't be a factor. My game rig would be considered a little on the "high" side in regards to power draw, being a current Intel rig and all. No complaints as far as noise/stability/etc, so far.
