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.
- addaon 1mo ago> They're trying NOT to say it had a 1440 watt power supply. It isn't, though. That rating is for circuit sizing. Power supplies are rated by their output power. If you assume an 89% efficiency for the power supply, and assume 1.0 PFC, and assume that it must be able to supply its rated power at the critical corner (low voltage), and assume zero margin on the current rating, then this is a 1068 W power supply. More likely its design spec is around 1000 W; it certainly can't be 1440 W.
