Thanks so much for those numbers. How did you get the measurements? The important thing to note here is that the Cube has a 220W power supply, so even allowing for spikes on startup or with heavy disk access 70-80 watts poses no risk. You could run a 23" ACD and still only be drawing 120 watts or so. The 28V supply for the ACD connector doesn't go through the VRM, so your choice of display won't affect that component.
