I'll PM you my bank details then.
Anyway, the PCI Express slot itself provides up to 75W. This is what cards that don't require a PCI-E power connectors use.
On top of that, a 6-pin connector provides another 75W, and an 8-pin connector provides 150W.
Even if you're only plugging in two 6-pin connectors, the card is being supplied with 225W, which is 75W more than the 660Ti actually needs.Reality Check:This is the 245W power consumption of a complete system
as tested by TR. That's using an 85% efficient PSU, meaning that with a 245W drain at the wall socket, the entire system
running at full whack uses around 200W (that's an X79 motherboard, a power-hungry "130W" Sandy Bridge Extreme, 4 RAM sticks, drives, fans, the GTX 660Ti and probably some silly lights too).
In other news, my first GTX460 (rated at 150W by Nvidia, just like the 660Ti) came with a single 6-pin socket. Go figure....Extra points
(page is chock-full of incredibly nerdy charts on wattage/current/pinout of the various PCI-E power connectors)
