I purchased this power supply to test out my current rig because it wouldn't power on. Knowing that Corsair has a very good reputation (from experience), I purchased this PSU.
The unit has more than exceeded my expectations so far, and even though it wasn't my previous power supply that was at fault, I am now using it in my rig. It seems very quiet.
I am backed up by the fact that it comes with a 10 year manufacturer's warranty!! So I feel confident that i'll have support for many years to come if I need it.
