A technician suspects that a power supply is faulty. How can it be checked?

  • by checking the temperature of the power supply
  • by using a multimeter
  • by taking apart the power supply
  • by powering up the PC after disconnecting each connector in turn
    Explanation:

    The temperature of the power supply does not indicate if it is operational. A PC technician should never open a power supply as dangerous voltages might still be present even when disconnected. Disconnecting the connectors in turn and powering the PC is not a recommended practice. In the absence of a power supply tester, a multimeter can allow to check if voltages are present.
