My gpu has two 8 pin connectors so can i use 8 pin cable extensions on my 6+2 cables from my power supply. I know i could just get 6+2 cable extensions but to get the pro cables from cable mod they have to be 8 pin extensions. Im assuming i could just plug the 6+2 cable into the 8 pin extension but just havent ever tried it before and thought that maybe for some reason they wouldn't fit because of the way the 6+2 connect together.
