So if you had a very good 350W PSU with appropriate PCIE power connectors and a strong enough 12v rail to cover the 14A peak of the GTX 760 and the rest of your stuff, then you could use it.

Those consume less than 75W (PCIE slot power only). They need about 6A at most to run. I run one on a 300W Seasonic PSU with obviously much room to spare.
