If you put the card in a PCI-e slot and put 2 8-pin power connectors on the card, you've got a maximum TDP of 375 watts. I don't see that as being far fetched, even though it does break the pci-e 300w maximum standard.
Actually PCI-E 2.0 supports up to 150W off the slot IIRC.
EDIT: NVM. Found someone who actually came out and said PCI-E 1 and 2 only provides 75W per slot. http://www.brighthub.com/computing/h...les/23289.aspx
