Just bumping this thread to provide some more info for folks based on some readings I took for my games. Also, some locales have Kill A Watt devices free to check out at the library... otherwise, spring for one online for $20. It's very much worth it...
Here are my readings for Amps. I only focused on levels when "running" since I don't turn all my games on at once, but I included the highest amps pulled during start-up as well.
