I'm building a pc for my friend that l used some of my own parts from my old computer. one of the parts were a penquin 550wat power supply which is pretty good for gaming since it has 550wat but i'm a bit scared of it been faulty or something. I did open it and clean the whole inside of it and l have turned it on and it worked fine. But I have never heard of this brand before. Is it some crappy faulty power supply for china or is it from a good company.?
Thanks
