Will it work?

I'm assuming the +12V2 is trapped with the CPU, so you have the +12V1@15 to work with for the GPU. Around 180w of dedicated PCIE juice. Not alot to be honest.

I'm not altogether intimate with 48xx power consumption, but from googling around the 4850 seems to sit around 110w, and the 4870 around 150w+. You'd be cutting it close with the 4870, I'd personally just go with the 4850, and if you're right about CF performance, it's probably the best deal in the end.
