Yes that PSU will be able to support that.

They used a system with an i7-920, which is more power hungry than any Sandy Bridge CPU. They showed their system drawing 564W under Crysis and 601W under Furmark.
So on maximum load you would be stressing the PSU to ~70-80%.
Remember that this is the maximum and your typical power draw will be much lower and the Antec is designed to deliver it's rated output (750W) for extended periods of time, as long as it is kept in conditions below it's operating temp.
However the fan might get a bit noisy, if in fact it does get stressed to 70-80%, so some might suggest getting an 850W PSU, if you haven't bought it yet.

I would not suggest using a WD Caviar Green for a boot drive, as it will be unnecessarily slow, while not saving that much power.
