And many website reviews of the GTX 560 Ti when it was first released stated the 560 Ti actually used more power than the NVIDIA specification.

GTX 460
Maximum Graphics Card Power (W) 160 W
Minimum Recommended System Power (W) 450 W

GTX 560 Ti
Graphics Card Power (W) 170 W

Being a retired engineer I feel if a company modifies the reference board it should improve it, not lower it. The EVGA GTX 560 Ti FPB uses the NVIDIA reference design but it looks like their standard GTX 560 Ti uses the GTX 460 design. NVIDIA used to control the allowed changes more and I think they should go back and tighten thier policies again.

Read this article on the EVGA website if you don't think they feel the reference design is the best solution.

Refinement of the fabbing process over time and revisions can yield cooler running GPUs.

I read several posts about later revision GTX480s running much cooler than the review models sent to us prelaunch.

Beyond that, it's hard to guage anything from PSU recommendations IMO. They have to make them high enough to account for cheap PSUs, unfortunately.
