Figuring out what power supply cables I need for SLI with few outlets left on PSU

[iranianburrito]

I'm trying to install a second graphics card to run two Nvidia GTX 560 Ti in SLI.
But I'm having trouble figuring out which power cables I need to hook it up properly.
(I already have an SLI bridge)

My power supply is a Corsair TX750 http://www.corsair.com/tx750w.html and it only has 3 free outlets left. here is a picture.
