At least I did some netto energy uptake measures.
The frame has currently an uptake of about 30Watt, w/o display this is 15Watt. I am not too happy with my ATX PSU it looses some power. The brutto energy uptake of the display is 15 Watt, but according to my previous measures the netto energy uptake of the display is 12 Watt, 3 Watt get burned at the PSU I'd assume.
Anyway, those 30W aren't too bad and I am looking very forward to the Efika2. My goal is to reach a netto uptake for an entire Efika2 based frame of <18 Watt (even better <15W).
