The video out logic is quite low power and the 4x0 cards still can output onto 2 displays and still have 3 outputs ( although they aren't always in use ). Then there is still the fact that the 480 is still pushing 250+watts with 1 display so regardless that doesn't change those numbers but I know where you are coming from with that. It remains that 188 is worst case with the 5870 where Nvidias 250 figure is suspect ( we've yet to see 3D vision surround numbers on a newer intensive game such as Metro 2033 so it might get even worse who knows ) Still this is the first time we actually will need a 1000watt psu for a 2 card system. In the past its only been needed with tri / quad configs or in high end bench settings ( ie highly clock LN2 benching / volt modding )
