Hi guys, I have following issue.

I've connected my new gtx 770 windforce gigabyte graphics card. It requires 6 and 8 pin connectors. My PSU is CD P750W and is more than enough for this GPU. But when I load any game and run it for 10 sec, the whole thing crashes and switches off. Then it turns back on and screen comes up, that PSU is instable. It never happened before. I also should mention that I've been provided with cables, though I used the original ones coming from PSU. I've noticed my 6 pin is regular, though the 6pin provided - 1 pin is blank, I guess the same with 8 pin. Does it matter?

That's a crap PSU by the way (no hard feelings).
 


Obviously it does!

6 pin and 8 pin:

No, I said that those that been provided with gpu has partially blank, like 6 pin got 1 blank pin and 8 pin got 2 blanks. Btw on +12V rail there are 15A, isn't that enough?
 


15 amps????? Darn! You gotta replace your PSU as quick as you can or you will be damaging your card completely!!

Your psu is providing barely 180watts and the graphic card requires 230watts!!!!!!!!!!!!!!! ALARM!!!
