Sounds like a generic brand...I wouldn't use it, period. I wouldn't even buy a PSU on eBay, you don't know if it has been messed with or something.
If a PSU in your system goes, it can blow up your entire system. In a really bad scenario, it can catch fire, setting your house/apartment on fire. Not something you want to mess with.
Get yourself something like OCz, Corsair (I think they make PSUs anyway), Thermaltake, Silverstone, Antec.
