I recieved a enermax 600w  noise taker power supply from zip zoom fly 2 weeks ago. I just read on new egg that alot of people say it's good, and alot say they are prone to breaking and are poorly built. I need to know before I take the parts to comp usa to have my comp built if the power supply is good or not.  Also if it isn't what is a good 600w power supply?

I'm still a few weeks off before all the parts will be bought so I still have some time, but I think it's too late to return it.
