How to Check a Computer Power Supply:
- Check that your power supply is switched on to the right power rating. For American households, you'll want it set to 120V
- Turn off the power supply off and remove all cables running the computer--except for the power cable
- Unscrew the series of screws located at the back of the case that are securing the side panel of the computer case to the frame. Slide the side panel off and set the screws aside for safekeeping
- Follow the thick braid of cords running from the power supply to the motherboard. The cable will lead you to a wide power port on the motherboard
- With the thumb and forefinger of one hand, take a firm hold of the power port while using the other hand to remove the cable from the port
- Plug the connector head of the power supply cable into the power supply tester. Match the squared bottoms of the cable's micro ports to those of the tester's port. For 20-pin cables, align the connector head to the left of the power supply tester
- Turn the power supply back on. Note the tester's LEDs indicators. They'll indicate whether the power supply is functional

- How do you use power supply tester?
First, open up your computer,and uplug the connector from the psu,that connects to the motherboard. Do not remove your PSU from the computer. Connect this connector to the Tester,and then plug the power cord into the PSU. The tester will beep, and then light up.
- Why does the -5v never test out when i put a power supply tester on?
Almost all motherboards dont require the -5v signal. just because there are no circuits no that require it. This -5v signal was orginally designed for ISA cards but since modern computers dont have the slot it isnt used.
- Can a power supply tester detect a defective PSU (as in one that could fry your components)?
Yes, if tester is equipped to simulate a load on the three main voltage rails then test the voltages. And possibly not, if tester could just test voltages under no-load conditions.
Good quality ATX 12V PSU should not fry PC components. Over voltage protection (OVP) circuitry for the three main voltage rails is usually independent of voltage regulator circuit. If PSU goes bad in regulating voltages, OVP detects it and causes auto-shutdown.
Generally, heavy PSUs (~2kg) have pretty sophisticated control and protection circuitry. Those that weigh less than 1kg usually just have the basics to conform with minimum requirements.
