At current clock, 143w. Fan uses ~7.5W, Rpi uses ~7.5w, so ~128 for the actual miner, not bad. Power consumption will be significantly better on the controller models, as the pis are not configured to change voltage, as well as beta software.
Humm Rpi should only use ~2.5W? But I guess you may loose some from the AC/DC conversion.
What power supply was provided for the Rpi? Just a Micro USB charger? or are you powering off of the USB from the Miner itself?
