PSU Cable: one 6-pin PCIe out of PSU, splits into two 6+2 pin PCIe outputs?

Hi there,

I'm currently running a Corsair HX650 Advanced High Performance PSU. I'll be upgrading my equipment soon (including the PSU), but I've still got a question regarding this unit.

My GTX 780 (EVGA Classified one) has just arrived, and I'd like to give it a test run.
It requires two 8-pin PCIe connectors. My PSU only has 6+2 pin connectors available, but I've read those should work just fine.

I've currently got 2 output slots for 6-pin PCIe cables available on the PSU. Both those cables, if used, split into two 6+2 pin connectors.

My question is:

Can I use a single cable to power the GPU (thus using one PSU output slot, one cable and the 2 6+2 pin connectors at the end of that single cable

or

Do I have to use the two sperate outputs on my PSU, run two cables and use one 6+2 pin connector on each cable to provide plenty of power to my GPU?

Honestly, PSU technicalities isn't my strong suit, so I rely on you guys to provide some advice :)  If only one cable can do the job, that's the route I'd go obviously, cable managment wise.

As always, any help would be greatly appreciated!

Yes you can use a single cable, it is a single +12 volt rail PSU and the cable can handle the amperage.
