I broke my last one because they said it was more powerful than it was and when both video cards started drawing power to play a game it fried :/

That's the problem with 'cheaper' PSUs I can't test it since I neither have a tester nor another working PSU, so I'll go to the computer shop tomorrow and have it tested there. If it IS the PSU, I'll file

an RMA with the manufacturer. NOT happy, though!

Guess what, I discovered that the PSU fried my GPU as well
