That is very borderline.
2 cards 300watts the rest of your PC from 150 to 200 watts depending on your overclock on the processor.
That PSU has 50A on the 12 volt rail or 600 Watts.
To error on the safe side I would replace it. Just gaming you should be OK but I would not run benchmarks or a full system stress test.

I estimate your power needs around 550W. If your PSU has only 600W on the 12V rail that isn't going to work. If your "700W" PSU has only 600W on the 12V rail that also tells me you have an older group regulated design at best. This means you don't even have the PCIe power plugs needed to run both of those cards. I advise getting a new PSU, one better suited for your SLI setup. (Or dump the idea of an SLI setup and just get the 1060 or 1070.)
