Will a 760W PSU power 2 gtx570?

For a system running with two GeForce GTX 570 graphics cards in 2-way SLI mode NVIDIA specifies that the power supply unit should have a combined +12 Volt continuous current rating of 56 Amps or greater and have at least four 6-pin PCI-E Supplementary Power Connectors.

The Seasonic X-Series 760W (X-760 SS-760KM), with its +12 Volt continuous current rating of 63 Amps and with its four 6+2 pin PCI-E Supplementary Power Connectors meets the requirements.
