I would probably only use one of the three redundant PSUs. Mwahaha.
But yes, it is clearly too much for my needs. Which is a shame, since I would like to be able to answer the question "What are you doing on your computer?" with "I am uploading stuff to my OCTOCORE SERVER."
ohh the power, here in the US I pay .09$USD per kilowatt hour and that thing looks like it could easily pull that, so 2.16 a day, 64.80 a month, and 777.80 per year.
