ATX Power Supply Tester

The myVolts ATX Power Supply Tester LCD 20/24 pin is a diagnostic tool for checking computer power supplies. It supports ATX, BTX, ITX and TFX form factors. The unit connects directly to the main power connector to verify output health. It is built for technicians and builders who need to validate a PSU before installation.

20 and 24 pin support with LCD voltage readout

The tester handles 20Pin and 24Pin ATX connectors plus SATA, 4Pin, 8Pin, 6Pin PCI-E, floppy and standard 4Pin interfaces. It measures +3.3 V, +5 V, +12 V1, +12 V2, -12 V and +5 VSB rails simultaneously. External connectors such as SATA and PCI-E use LED indicators rather than the LCD display. The LCD shows each voltage and the PG value for quick assessment.

Audible alarm and PG monitoring for fault detection

A built-in buzzer sounds a continuous warning tone when any measured voltage falls outside the normal range or the PG signal is missing. The corresponding value flashes on the LCD to identify the faulty rail. The device requires the 4Pin connector to be attached alongside the 20Pin or 24Pin plug to avoid a false LL error. It is not suited for users who need automated logging or software-based reporting.

Preguntas sobre este artículo

Will the tester work with the 20-pin ATX connector on my older power supply?

Yes, it supports both 20-pin and 24-pin ATX connectors so you can test legacy units directly.

How do I know the tester has completed a successful check?

You will hear two beeps at startup and the LCD will show steady voltage readings without any values flashing.

Does the package include cables for SATA and PCI-E 6-pin connectors?

The tester has dedicated ports for SATA, 4-pin, 8-pin and 6-pin PCI-E connectors built into the unit; no separate cables are required.
