Hi i have a GTX 780 Ti (Sc Acx Version from Evga) And a Supernova G2, I am power my graphics card with the 2 cables required, but the 8 pin in the card goes to a 6 pin plugged into my psu, When i run Valley benchmark with slight overclocks it always says its the voltage and the lack of power holding the card back (Gpu-Z)
Do i need to swap it for a 8 pin to 8 pin?

You should connect the 6+2 Power Pin into the Card and then it will sort its stuff , or you can see the HW monitor and tell us how many volts on the 12V Rail.

I'm not quite sure what you mean. You are using PCI-e cables to go to your GPU right? They typically are 8pin on the side that plugs into the PSU, then 6+2pin (8 pin) on the side that plugs into the GPU.

You are saying you have 8pins connected to the GPU, but only 6 going to the PSU?
