um, yes way, that load figure is for the whole system
power draw, you can't just triple it, anyone running those types of video cards is running some other power hungry components as well which add to the total power draw making that first figure high, those numbers are not just for the card itself...
also, the OP never mentions 4870x2s (which for scaling purposes would be pretty useless, even scaling for crossfired 4870x2s is questionable), he only mentions three 4870s, which draw less power, a system with three 4870s could be handled by a 850w-1000w psu, you do realize that everyone can't just buy a 1500w psu, slap it into a high end system and run it in their home and expect it to draw that much of a load from their outlet, don't you...? read some 1500w+ power supply reviews and you'll see that the average home electrical outlet wouldn't be able to handle it at full load...
