base Roamio power calculations / tests

I'm starting to have suspicions about this and I'm hoping an inquisition will put it to rest definitively or find a work around that will improve the picture.



I'm ignoring the 6 tuner Roamio because it should have a completely different, beefier supply.



I'm not 100% certain how to go about everything, but it should become clearer as it gets further along.



To gather some initial information:

Specs:

the included Power brick

the included HD (idle, operating, spin up)

typical (AV-GP?) HD upgrade (idle, operating, spin up)

worst case (10k rpm?) HD (idle, operating, spin up)



Measurements:

confirm above specs by measurement

board consumption (boot, typical, peak)



Subcomponents (hopefully they can just be aggregated):

fan consumption (low, high, spin up)

cable card?

Wifi card

RF card?

USB?
