1080 General Building Question

[Jqwop]

I have purchased a EVGA GeForce GTX 1080 FTW DT(http://bit.ly/2m0DWrx)  and have a modular power supply corsair RMx 750(http://bit.ly/2lOlKkG). I currently have in my system a gtx 960 which requires only 1 input power and this is the first computer I have built. On my 6+2-pin pcie power cable there are 2 6+2-pin connectors.

Do I have to run 2 pcie power cables to the graphics card or may I use one?

If I use only one are there any drawbacks?

You have to use both. It will not boot without both.

Welcome to the Forums!

 

You will need to wire up both connectors but can use a daisy chained (dual 6+2pin) cable on a single GPU. It's only a concern for extremely power hungry GPU's that may require two completely separate cables.

Thank you was unsure and wanted to check before I installed and or changed anything.
