The only other thing is, as the other guys said, it WOULD be a good idea to go with a more well known model of power supply. You know why I think that, so I'll leave the decision up to you.
ok a couple of things. first of all I dont know why you all are concentrating on a power supply that has done me real good for the 4-5 years I have had it just because it's not a "Name Brand" PSU.
No it doesn't. There are people here with orders of magnitude more experience than you and they know what they know because of all the evidence they have seen. There are numerous reasons why your PSU could have survived for so long, including the possibility that it is actually a quality PSU but because it is effectively unbranded we can't know for sure.
