I have the black version of the 49 port Eyeboot, primarily because it's not orange. It will run on 110 or 220V and the black one has power supply built in. I have 18 sticks running on it (at 200) along with 2 arctic fans. It runs like a charm - not a single hiccup in two weeks. They are great hubs, not cheap but really solid and plenty of power/port.

I have not run the power consumption numbers vs my Antminer S9's. I am getting close to 500 Ghz on the 2Pac rig. Some bizarre internal side of me wants to see if I can get it to 1Thz. Certainly not a practical project from a cost perspective. My wife likes the blinking lights so I have that going for me, and they are so quiet compared to AM. Have 12 of those running and it is NOT quite . Think I just found myself a weekend project to see how much power in consumes per Thz. I certainly know the Antminers pull 1350W for between 13.5 and 14 Thz. I think they pull about 1.5 amps at 200 so not going to take long to do the math but want to actually test the circuit.
