    Corsair power supplies have always been dependable for me, and this one is just the same. When you power it on or off, it makes a slight "click" noise. Some people find it annoying, I personally don't mind since the rest of my system is not loud at all. FYI, the connector wiring to GPU can be a bit stiff in case you have to bend them 180deg, so I bought straight cable adapters instead.
