IIRC The delta unit has 3 12v rails:
22A on rail 1
22A on rail 2
25A on rail 3
Rail 3 is dedicated to both the PCI-E connectors. I don't know if 25A @ 12V (300W) is enough to drive a GTX 680...
This information is incorrect. The
EA-650 Green has two +12V rails, each rated at 38A or 456W. Of course, this doesn't mean the PSU is capable of 2x456W on the +12V, instead it's limited to somewhere around 650W. Over power protection takes care of that.

edit: It also says it is SLI ready. How could that be possible if I cannot even power one card?
"SLI ready" just means Antec paid for the certification. It's marketing. Of course, it does mean it actually is SLI ready, but so are many PSUs that don't advertise it.
By default, the EA-650 Green has two PCIe connectors so it can only SLI graphics cards that require one PCIe connector each. But given the power on each +12V rail, it shouldn't be an issue to SLI two graphics cards that require 2x6-pin each, using adapters. Such cards typically consume around 150-170W which is only around one third of the +12V rail, leaving enough power to be distributed to the CPU, motherboard and other components. I'd be a bit wary about going SLI with GPUs that require 6+8pin.
