Ok I have a modular power supply (evga 750 G2) and I would like to custom sleeve it. The problem is you can only do a 8 pin to 8 pin or 6 pin to 6 pin gpu power. The power supply only has 8 pin pci expansion ports. The question is will it work to plug a 6 pin connector into that 8 pin connector ON THE POWER SUPPLY. Thanks for any responses
