Thanks for the report! Very encouraging...
But could you state how you measured those values? It's an important detail for those who are interested in how your results compare with hardware of the same class. It's not a surprise it consumes less than an Asus board but the actual values are surprising (to me anyway).
Since you didn't state your location, your mains voltage and ambient temperature could be useful as well.
The main voltage here in Switzerland is 230V, the ambient temperature was about 26°C. To measure the power consumption I've used this power meter:http://www.gt-support.de/files/IM_GT-PM-04_D.pdf
Also, do you know what the BIOS "power policy" actually does?
Unfortunately I don't know what the power policy in the bios does, I've also not noted any difference in the idle power consumption between "low power" and "high performance".
I've also enabled the DIPM for the disk (by default only the HIPM was enabled), but I've not checked if this make any measurable difference in the power consumption.
In the configuration of the system during the measurement there was also a sony slim DVD writer (AD-7713H-01). It adds about 0.1-0.2W in the total power consumption.
