ATX Power Supply Tester with LCD

The myVolts ATX Power Supply Tester LCD checks ATX, BTX, ITX and TFX power supplies. It connects to the 20-pin or 24-pin main connector and displays each rail voltage with ±0.01V accuracy. A built-in buzzer sounds when any reading falls outside normal limits.

Thermals Noise and Power Draw

The tester draws its operating power directly from the supply under test so no external adapter is needed. It has no fan and produces no audible noise during a check. The LCD remains readable while the unit is powered by the PSU itself.

Bundled Connectors and Alerts

The package includes leads for P4, P6, P8, SATA and IDE outputs. Only the 20-pin and 24-pin connections show voltage on the LCD; the peripheral connectors use LED indicators instead. The buzzer and flashing display give immediate warning of any fault.

Perguntas sobre este artigo

How do I connect the tester to a 24-pin ATX supply and what step is often missed?

Plug the 24-pin cable from the power supply into the tester's matching socket; the unit powers on immediately from the supply itself, so no separate battery or mains lead is required.

What part will need replacement first during long-term use?

The piezo buzzer that sounds the fault alarm is the only moving component and will eventually wear out after repeated audible alerts.

What limit appears first when the tester runs continuously on a loaded supply?

The LCD voltage readout is specified to ±0.01V accuracy; sustained operation does not introduce any additional thermal or timing limit beyond that display precision.
