Should be more than enough. Power consumption is roughly 300w for two cards plus add another 200w for the rest of the system plus overclocks, assuming 80% efficiency, that would be around 400-450w that your system would use. Obviously if you were to run furmark or something similar, the load consumption on the gpu's alone would be 50-100w more. But who runs Furmark these days anyway biggrin.gif
