This might be a really stupid question, but I'll ask anyway. My 8800gt has a 6 pin hole power thing. The PSU has an 8 pin power cable as one of the attached cables. Instead of using the modular 6 pin pci power cable, can I use the 8 pin cable thats attached to the psu with the extra 2 pins sticking off the side? I just want as few cables as I need.
