power and energy

211 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 you think of the power supply like a pump, and say it can deliver 1 gallon of water a minute – assuming the hose connected to it is wide enough – then after an hour it will have pumped 60 gallons of water right.

Well your PSU can pump 700w of power, and if it’s connected to a wide enough pipe it can have delivered 700wh in an hour
