It depends on the power supply's conversion efficiency at that specific power draw level.
If the conversion efficiency is exactly the same at that power draw level on both power supplies then the power consumption at the AC wall outlet will be the same for both power supplies.
If one of the power supplies has a better conversion efficiency at that power level then it will draw less power at the AC power outlet.
If the power supply has 80 PLUS certification there should be a published conversion efficiency graph available for it. Select a manufacturer from the list and click on the specific model you want to look at here:http://www.plugloadsolutions.com/80PlusPowerSupplies.aspx
