power and energy

209 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 ?

Just one small correction, Joules is a measurement for energy not power. Power is just the amount of energy used over time and 1 Watt is equal to one Joule per second
