Powering the graphics card (may be a stupid question, my name says it all)

Ok, first off, this is a re-post of a question with correct information about the situation and a picture for good measure.
I have a GTX 770 in my new computer which requires 1 8pin and 1 6pin connector to power it. The PCI-e cables that came with my PSU (Antec 750w 'modular' High Current Gamer) have the end that plugs into the PSU (obviuosly, i'm just trying to be as clear as possible) and then a 6+2 pin connector (a 6 pin with 2 that can be joined to it). There are two of these at the end of the cable, so two 6+2 pin connectors on the one cable.

While the one cable has sufficient connectors to power the GPU, my friend thinks i should use 2 PCI-e cables because he doesn't think 1 cable will be able to provide sufficient power, despite it have enough connectors (basically pretent that the cable only has a single 6+2 pin connector on it).

Is it necessary to use 2 cables to connect the graphics card to the power supply or will it receive the same amount of power if i just use the one cable. Here is a picture to help explain what im talking about. Okay, no picture, i can't figure out how to get it on here from a file and not a URL...
Thanks, (you guys have to be sick of me asking questions by now.....)

No you don't need separate cables to run it.

They make the cables like that so you can use one.

Is this your power supply?

There is no reason to use more than one cable if the one you are using has the correct connectors on it. Unless your power supply has multiple 12v rails and the PCIe cables were on different ones, your friend is wrong and your 6+2 connectors on the single cable will be fine.
