Hardware Secrets posted a review on the Thermaltake Thoughpower 1500 W Power Supply

Thermaltake Thoughpower 1500 W is probably the most power PC power supply in the world – so powerful that it can't be sold in the USA, as it is over the maximum allowed power for household appliances set by the Underwriter Laboratories (UL) – which is 1,300 W, by the way. Because of that, this model can only be found in Europe. The architecture used is really interesting: this power supply is in fact two completely independent 750 W power supplies inside the same housing. Besides its monstrous power capability – which the manufacturer says can be delivered at 50º C with a peak power of 1,600 W –, Thoughpower 1500 W has a modular cabling system with a total of eight power connectors for video cards and a 140-mm fan. In this article we will completely dissect this monster.
