Hi,
 
Does anyone know from a technical perspective why EVGA went with an 8 pin and a 6 pin power connector for their GTX 760SC card? 
Why not a single 8 pin(75W + 150W) or dual 6 pins(75W + 75W + 75W)?  
 
Thanks

Welcome to the EVGA Forums
 
Probably the power phases over the 30 Amp draw
 
up to 300 Watt draw when OC

Hi Knightrunner and welcome to the EVGA forums! Since these are gaming cards and we do engineer them with the option to overclock in mind, we plan their design according to the highest overclock (theoretical OC) possible which calls for an 8 and 6 pin power connectors.

Thanks for the quick reply.  So, at stock settings under a gaming load the card is most likely not drawing any power through the 6 pin plug?

That's not quite how that works. Even at idle, the card would be pulling power from all power sources but the power draw is distributed more evenly.

I understand now.  The power and ground wires are connected together across both the 8 and 6 pin connectors on the card and the current is split evenly (minus resistance differences) across both paths.  So at stock speeds,  the card will be fed with enough power (with plenty of headroom) from two 6 pin pcie connectors from my psu (with one adapter for the 8 pin connector on the card) and of course the mobo slot itself.
