Right now we have no idea what kind of power it uses. I have a Two Up that should be here this month, And I also have a Kill-A-Watt that I could test how much power it's pulling.

I think the printers don't use more then 60W without the heated bed or they wouldn't of been using a 60W. There going to the bigger power supply to be more reliable in the long run. This is my first 3D Printer so I can't really help to much, But I did order the heated bed for my Two Up but the heated beds won't start shipping till January.
