Nvidia gtx 570 running on a 620w psu

[Tristo85]

hey i have a core I7-2600k OC to 4.2ghz and a gigabyte GTX570 {oc version but not over clocked} and an antec neo eco 620W PSU, the other day i left my computer idling while i went to the store and came back to a black screen and the gtx fans revving flat out. this has happened twice and now it wont turn on at all. and the computer doesnt even recognise its even in there., would the card be dead, should i get a bigger PSU or just buy a new card.

Have you tried taking the card out and booting off the onboard graphics?

Try that first...

Are you sure it's not your CPU overclock?

 

[Tristo85]

Yeah. On board works perfect. I can play some games. And yes cpu is oc but not graphics card. If I take the card out for a week it works for a few days but this time it hasn't worked again.I thought it might be too low psu. But according to 3mark sites tests it doesn't use more then around 400 with an oc i7.

Solved the problems by getting an 800w psu. Runs perfect with both cpu and gpu overclocked. So anyone with the idea of getting a gtx570 make sure you have at least a 750w psu.....

Are you kidding me? A 500-600w PSU would easily power a gtx 570.

obviously not man.. cause my 620w PSU couldnt run it, {though i do have my CPU oc, 5hdds a bluray drive and a lot of other *** aswell, but now that i got the 800w havent had a problem yet. and now i even have it OCed aswell runs like a dream.
