AMD does not have a good record for low power consumption and there is no data on newer offerings
http://www.tweakpc.de/hardware…srock_qc_5000-itx/s06.php
under the heading "Leistungsaufnahme"= power consumption you can find the value for the ASRock QC5000-ITX/WiFi, it is fully equipped MB based on the A4-5000.
It requires 17 W in idle.
Probably with a basic model as the ASRock QC5000-ITX/PH, without an graphic usage and wifi card could be possible to reach a good value.
What do you think about it? I'm pondering to purchase it. I'm not experienced with it, so...would you support me with the test/reviewing of that MoBo?
