I use actual 23 Antminers on 4 Dlink DUB-H7 - 3 are full and one just with 2 miners at the moment. The HUBs are powered by a 350W PC-Supply and Ants are running without mod on 0A81 stable. Cooling from downside from power-supply and from front with 120mm Fan running on 5V silent. At all actual power consum 72W ! I have an asic-cube also taking arround 300W for less GH.
