So I recently bought a gigabyte Gtx 560 GPU. I uninstalled my previous cards drivers (a 9500 gt) and physically installed the 560. After several trials, I found my PC won't turn on when I have the two 6Pin pic express cables plugged Into the GPU, the PSU just flashes once and turns off. Without the cables in, my PC powers on but the screen stays black. I'm starting to think my PSU isint strong enough for the 6pin PCI cables - even though the card requires 500w and I have 500-600w peak. I wanted to get some feedback before I just go upgrade. Do I need more power?

PS: everything works fine with my old card

Mobo: Foxconn aloe 1.01
CPU: phenom x4 II 2.8ghz
PSU: Rocketfish 500w-600w peak
 
Hello,

Your PSU is definitely junk. Rocketfish - I just had to LOL when I saw that.

Check this article out:

Apparently Rocketfish try to rate their PSU's approx 100W over their limit. And are just designed horribly.

AFAIK you need a quality 450WPSU for a stock GTX 560. Something like Antec, Corsair or Seasonic. However I wouldn't go that low, maybe something like a 500 or 600W PSU.

Do you have a spare one to try out? From a friend.

That is one of the worst PSU's out there. Here are a couple of links to 500w PSU's that are good. I hope that is the problem. Maybe you could try your card in someone eles rig?

If it is your card then you will have to RMA it ASAP. But the links I gave you could from there look on your own but look for the brands that Chainzsaw listed. Another one is XFX brand. I wish you good luck on this.
