For a system using two reference clocked GeForce GTX 670 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater power supply that has a combined +12 Volt continuous current rating of 45 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

For overclocked graphics cards I would add at least 7 Amps to the amount recommended above.

The Seasonic X-Series 750W (SS-750KM), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with two overclocked GeForce GTX 670 in 2-way SLI mode.

There is enough spare capacity to handle any CPU overclocking you may want to attempt.
