What is a Power Supply Tester?

A power supply tester is a diagnostic tool used to check the voltage output of a computer's power supply unit (PSU). This tester features a clear LCD screen that displays the voltage levels for various connectors, allowing for quick identification of potential power issues.

How to Use the PSU Tester

Simply plug the tester into the corresponding connectors of your ATX, BTX, or ITX power supply, including SATA HDD connections. The LCD screen will then display the voltage readings for each line (e.g., +12V, -12V, +5V, +3.3V, +5VSB). This helps determine if the PSU is functioning within acceptable parameters.

This tester is compatible with a wide range of PC power supplies and is an indispensable tool for PC builders, technicians, and enthusiasts looking to ensure their system's power stability.
