I recently bought several antminer s4's from zoomhash and have them set up, however I need to underclock a few to be able to run them in the same room. The power breaker trips with the last ones running and I can't run them anywhere else, so they are currently just sitting in the room. Does anyone have a bit of information on how to underclock them, or a chart detailing the hashing to power rate?

Thank you for the help.
