What power supply tester for this?

[Chrislw324]

+These are the connectors on my power supply. Do I need to get a certain type of tester, or would a standard power supply tester work?

They look normal to me. The one in the middle looks like floppy power.

Look at the colours of the wires to see what voltages go where. Actual PSU testers typically cost a few thousand dollars, so don't expect to get one.

It's a proprietary power supply, the voltages will be listed on the label (see wire colors)

The P2 labeled connected used to be on AT computers (before ATX)... as in Socket 7 and before.

I suspect they reuse the connector with a different pinout for the power on signal , power good signal, some standby voltage ... and the other two connectors probably carry only 12v.

 

You'd connect the PS_ON wire to ground with a wire or a low value resistor (ex 100 ohm) to turn on the power supply and then you'd use a multimeter for basic voltage measurements.

For something more serious you'd need a constant current load and maybe an oscilloscope
