Question

you are servicing a clients computer that has been randomly restarting. you decide to test the power - supply voltage on the 12 v rail using a multimeter. which of the following best describes the action you should take based on the multimeter reading shown below? 10.24 keep using the power supply, but stop using that 12 v rail. replace the power supply because it is failing. continue using the power supply until the voltage drops to less than 9 volts. switch the voltage selector on the back of the power supply to 230 volts ac.

Explanation:

Step1: Analyze normal voltage range

A 12 - V rail in a computer power supply should have a voltage close to 12 V. A reading of 10.24 V is significantly lower than the nominal 12 V.

Step2: Determine power - supply condition

This low voltage indicates that the power supply is likely failing.

Answer:

Replace the power supply because it is failing.
