I run my I5 750 and a gtx560 with a be quiet straight power 450w of the old e5 series.
dont trust them that you need a always a 800 w psu. thats bullshit.
i work for a huge hardware seller and i know that even gtx570 run well with a good brand mark psu with about 550 or 600w. its all about effeciency.
However, it could be that your psu is damaged. you still have warranty. the dark power series is able to run even two midclass cards in SLI without problem. its all about combined ampere in rail and not the max power output.
