I did some amount of power consumption in idle mode of IC on DE1-SOC:

I don't know if this numbers are so realistic... but 1.7W is what is left from PowerPlay Early Estimator that say me that system take 1.7W (max not typical but cyclone v yield make max typical) :)
(Clock), Ethernet and Video DAC are very power-hungry :(
