GTX 780 Lightning Help

[lukezon]

So this is my first time building a system and I am installing a 780 lightning card.  My PSU came with 3 8pin cables.  One of them is straight 8pin to 8pin, and the other 2 are a single 8pin - 2x 6pin + 2.  How do I power this card?

 

PSU: Corsair RM850

use 2 x 8pin

 

Edit: Join the 2+6 to make 8

With two 8 pins.

 

The 6pin + 2 can turn into an 8 pin.

use 2 x 8pin

Which one is that?

[lukezon]

With two 8 pins.

 

The 6pin + 2 can turn into an 8 pin. 

Will that give it enough power?

[Rheinwasser]

just plug all in.

where is the problem?

Yes use the 2 8pins

Yes, with the 6 pin + 2, you have the option to just plug in the 6 pin or plug in the 6 pin and the 2 pin additionally. So you use two 6 + 2 pin. As you said  "other 2 are a single 8pin - 2x 6pin + 2." So two 6 pin + 2, equals (8pin x 8 pin) 16 pins total as long as you plug all of them in

Plug in the connectors that say PCI-E on them into the graphics card. The one labeled CPU goes to the 8 pin connector on the motherboard.
