I have a small single board computer. According to the manual the came with it:
- when powered by a 5V ATX power supply, average consumption is 1.90 A (9.5 watts)
- when powered by a 12V ATX power supply, average consumption is 0.07 A (0.84 watts)
So the board uses 9.5 watts for 5V operation and .84 for 12V operation. Does this sound right to anyone else? Why would the board use 10x the power at a lower voltage. Plus, does <1 watt for an embedded Intel Atom processor 1.6 GHz single-core (N270) sound correct?
