How can I determine if wires have power by testing them?

To determine if wires have power, you can use a voltage tester or a multimeter. First, ensure the power source is turned on. Then, carefully touch the tester's probes to the exposed wires. If the tester indicates a voltage reading, the wires have power. Be cautious and follow safety precautions when working with electricity.

What is the most efficient way to determine whether your power supply is bad?

There are 2 easy ways to check, but both require some extra equipment. The first, and easiest, is to use a power supply tester. If and when you have one, unplug the power, emove the power supply connector from the mobo, plug that into the tester, and the results should be immediate. Most of the testers have different colored LEDs to indicate the results. The second is to connect a different power supply of the same or greater voltage to your computer, if you have one. If your problem goes away, then it was the PSU, if not, keep troubleshooting. Good luck Bob

Always follow safety precautions and wear appropriate protective gear when working with electricity.


What is a power supply tester and how does it work?

A "power supply tester" is pretty generic. It can consist of as little as a simple fixed value power resistor to serve as a load. That might be alright for a production tester where there's only one type of supply being tested. More for development I use a DC programmable load. This is a electronic load that can be programmed for a specific constant current or constant resistance and also switch between settings for dynamic step response. They usually have ammeter and voltmeter to monitor the load voltage. An external oscilloscope is useful to monitor ripple, and noise and step response. I also have a complete AC source setup for AC/DC power supplies. where I can vary the input voltage and frequency. Its based around a programmable AC power supply. I usually have a P44 Kilowatt to check input power and power factor.
