Post Watts needed for SLI?

This question may appear redundant but I am planning to build my first PC rig, and the last thing I want is not have enough power to run my computer.

I was looking at getting the GTX 560/ti and I checked the nVidia website and they said minimum power requirement is 450 W.
GeForce GTX 560 - Specifications - GeForce

My question now is, how do I calculate what the minimum power is needed when another GTX 560/ti is added?

In general, how do you calculate those ratios for future reference?
