Thread Starter 
hi guys

i have thermaltake toughpower 750w.
i lost 8-pin 12v power connector (PSU to Mainboard).
and my PSU also has 8-pin PCI EXPRESS power connector (BUT it is PSU to Graphic card)

Can I use 8-pin PCI Express power connector(not 6+2) instead of 8-pin 12v power connector(PSU to mainboard) ????

thanks in advance

No it is not the same! The grounds and power are different on the PCI-e and you might end up frying anything connected to the psu.
