Did you measure the consumption, or is this a comparison of the rated draw? Or, pput another way, how much do you trust what the HMC tells you? I have recently measured the consumption of a number of desktop machines and small servers (including an MP3000), and in all cases the actual draw is far lower than the nameplate rating.
