Depends how much gear you have running of it, and your asking the wrong guys I think, this is more of a hardware related issue.
I had a 600 running a i5 with all the basics, but when I did a re build and put it into a Antec Gaming case with all the lights, and a SLI running this time it shagged it self.
Tell us more about your system... do you overclock? How manny fans, cards, and Hdd's do you have running of this Psu, if it is the Psu that you are worried about
