what you do is you take your total watts.. les say 500 and divided it by your voltage.. we'll say 120.

so you have 5 computers that all run at 500 watts. that comes to 2500 watts. then you take that and divide that by your voltage we'll say 120 but some are 230 (i believe) which comes out to 20 amps.


Keep in mind I just took the Wattage of your power supply. you need to take the wattage of your..

laptops, monitors house fan, lights, tv if you have one on and other stuff.

I am sure you will need to pull from 3 different breakers at the least. :wink:
