When a card has the potential to pull 300 watts by itself I would want more than 150 watts headroom for everything else. It might not usually pull max power but I would rather not find out by the burning smell and broken computer that one game or the other did max it out.

Around 200W max during normal gaming and almost 300W peak during stress-test with things like Furmark. 750W should be fine as long as he does not run artificially GPU-intensive burn-in benchmarks.

Except the extreme power draws are only achievable through synthetic burn-in tools. Not games. And with SLI/CF, cards are unlikely to simultaneously hit peak power in games since each GPU would be at different stages of rendering their respective frames.
