power and energy

214 views

Hello,
There is something I don’t get about power and energy.
If I got it right, power is expressed in Watts or Joules ans energy is in Watts.hours.
So if I buy à power supply rated at let’s say 700W. Does that mean (assuming, for the sake of the argument 100% efficiency and 100% load) it also consumes 700Wh ? And also that 700W is it’s maximum power output ?

If it’s rated for both 700W and 700Wh it will discharge 700W for one hour before running out. It could also discharge 350W for two hours, or 175W for four hours, etc.
