I bought my Atom machine, ITX-M4S2GAP, by accident(my relative clicked the photo next to the one I wanted).
At the very first test, it consumes 26~30W due to a usual 300W PSU, one DVD player, and an old 10G HDD. Each one contributes a few Watts. With a 4G CF card and 12V DC PSU, the power consumption stays steadily at 16W. The only problem is SLOW since I try to put ClearOS and asterisk into it. The bottleneck might be the I/O speed of CF card.
With 2.5" HDD(3~4W), the power consumption is below 20W. |
