You suspect that a power supply is faulty, but you use a power supply tester

to measure its voltage output and find it to be acceptable. Why is it still

possible that the power supply may be faulty?

Is that voltage consistent? That's the key. Also, if the wattage is underpowered

then the power supply won't supply enough power for that computer.
