I thought it was funny years ago when apple would report the power in watts of some systems like the mac mini.

But for the mac pro, they would say something very obscure.

"100-120V AC or 200-240V AC (wide-range power supply input voltage)" and the maximum current is "12A (low-voltage range) or 6A (high-voltage range)".

They're trying NOT to say it had a 1440 watt power supply.
