Question:

The number of computer power W is to look at the rated or maximum?

The number of computer power W is to look at the rated or maximum?

Answer:

In general, the nominal power supply products are marked on the nameplate of the output power supply current, you can calculate the actual rated output power, but this is not accurate
The power rating is often measured by AC load, which is to measure the maximum voltage of the output voltage by detecting the voltage drop and ripple coefficient of the main voltage of the power supply.
But there is no specific formula for the power rating of the power supply.
W power of the computer, of course, look at the rated power.
