1Pcs 20/24 Pin LCD Computer PC Power Supply Tester for ATX BTX ITX TFX SATA with Buzzer Automatic Alarm

detected that my psu was going out 10/10 I even used a known working psu to test and is giving accurate readings!

El producto fue tal y como se ve, cumple su función.

I bought this to test an old gaming computer power supply. It worked well however not something you use often.

Where the unit doesn't put a load on a power supply it does display the output of the cables it hooks to. It is a quick and easy verification of the power output on the specific rail but not really the type of tool that for sure determines good/bad.I have seen various videos where people will add HDD or car headlamps to simulate a load alongside testing.

The ATX part worked OK but there were no instructions and no indications of how some of the connections should be used.
