You also have to factor in heat/noise coming from the psu. When you put that big of a load on a smaller psu, the psu will likely run hot and the fan on the unit will also run loud. Effeciency is also another thing. If your only using half of a psu's rated wattage, that is usually when it is the most effecient.

Having said that, if you really want to take the risk of running these big expensive gpu's on a cheaper small psu, then go right ahead.

Personally, I wouldn't run these on anything less than a 750w, just to be safe. Plus, you would then have some oc headroom if you wanted to overclock the gpu's.
