Re: {OTish} Power consumption

["Simon Rafferty" <simonr@xxxxxxx>]

I stuck a standard PC on my HAWK Energy monitor to see what current it
actually draws (we needed to quanitify it for an office energy survey).
Even
on startup it was drawing 150w max and on idle somewhere around 90w. So
fear
not, BUT stick a SCSI HD in it (10k or faster) and u can watch that power
consumption go up by 20-30w - All of that heat has to come from somewhere.
Also some of the new high end graphics cards  pull quite a bit of power too
