X-bit showed the 6800 ultra to use 72.09 watts (under load) as measured at the card (including the agp port, which used minimal power). More interesting was that increasing the gpu from 400 to 440 and the memory from 1100 to 1200 showed a total increase of only 4 watts. This 10% increase sugests that total oc load is then only about 44 watts (gpu and memory combined prior to voltage stepdown)

It also needs to be mentioned that the ultra is 280 sq mm. At 35 watts it has the same watt per sq mm as a amd64 winchester (90 sq mm) does at 11 watts
