What is the role of PSU in a computer?

Does a PC PSU use all its power?

6 Answers. No. A 500 Watt Power Supply can DELIVER 500 Watts, but it will ever use only as much as the components in your PC need (and of course that depends on Load and Activity, if Energy Savings Mechanisms like AMD’s Cool’n’Quiet or Intel’s SpeedStep is enabled etc.).

Where is the PSU on a computer?
