Never heard of that brand. Probably crappy one that you bought or came with your case. Trash that an get an 550W Rosewill SLi. Unless that 550W has 30A+, junk it.
And, there was a problem with a power supply i bought before. It had an adjustable power input(or output, I cant remember). It blew up and took an old motherboard with it. I dont know how it happened and dont want it to happen again.
