Hello everyone! I have a x58 classified mobo and my powersupply only has 1 8 pin 12V connecter to go to the processer. I was wondering is there any reason I cant use a 6 pin pci-express connecter on the second connecter?

RTFM before you fry something. No you cannot use a PCI-e connector in there. You only need to connect 1 8-pin connector, if your power supply has 2 then you can use them but the motherboard will be just fine with only 1 in either of the connectors.

No. The pinout is wrong. If you try to use a PCI-e power connector there, you will short the 12 volts to ground. If you are lucky, the PSU will detect the short circuit and electronically shut itself down.

Connect just PW12-1.
If they come out with very power hungry processors, the second one might be necessary.

:pfff:
Read page 22 in the Manual.
The second ATX_12V connector is needed if you are doing Extreme overclocking.
DO NOT PLUG A POWER CABLE WHERE IT DOES NOT BELONG :non:
