I'd love more pics / info if possible on them. I'm interested in running a similar set up, though only starting with two miners and a single dps 1000w psu. What are you making around $15 a day? Only a couple months and they will pay for themselves!
You might find this thread I started useful. IMO its much better to use a server PSU then an ATX PSU. 1 its 5x cheaper to buy, 2 your not running at 90% load and 3, server PSUs are made to be hammered 24/7. Only down side is its fecking loud!
When I go to visit the miners next time, I will get the wattage at the wall.
