It depends on the GPU and the amount of underclock. GPU's come in many different flavors so there is no simple answer to your question.

There is no easy way to answer that question because of the many different factors involved.

Rated power consumption and underclocked are mutually exclusive. They rate the power consumption for the worst chip in the batch under full load at full clocks then add a bit to be safe.

Your best bet is to buy a kill-a-watt meter and use that to see how much your systems power consumption decreases when you underclock the card. Power consumption of a circuit as complex of a GPU has far too many factors involved to attempt to figure it out theoretically, your only option is to check experimentally.
