It's pretty impressive to me that 3 top of the line cards only draw those numbers at the wall. The PSU used is a PCP&C 1200W and the 2600K was OC'd to 4.8GHz. Assuming 85% efficiency they are using 595/700W power, not bad at all.
Who needs 1200-1500W PSUs, even for 4 GPUs on this generation unless you are using 4x non-reference cards with dual 8-pin and massive volt modding.
