If memory serves, there are no 2000w power supplies out there, at least any designed for ATX systems... I think they cap out around 1000-1100w right now.
As far as the pictures... It was kinda a giveaway when I noticed that the card shown had what appeared to be 10 VRAM chips showing on that side; the GTX 280 has 16 chips, and the 260 14; a dual-GPU setup would mean that it would likely have an equal number on the back side, for only 10 per GPU.
The last giveaway was that I only saw a single 8-pin plus a 6-pin power connector.
