I was working based on this paper written by Google researchers in June 2007, which refers to one of Google's "typical" servers having a theoretical peak power of 213W and an actual peak power of 145W:

While I agree that in general information about Google's systems is a mix of inaccurate and out-of-date, I think it's probably safe to trust numbers given in research papers published by Google... especially when the numbers deal with how much power is being used, and the topic of the paper is power distribution within datacenters.
