You may need a separate multimeter for deeper circuit analysis if the LEDs indicate a fault but you need precise voltage readings. Keep the unit clean and store it in a dry place to protect the plastic housing and internal contacts. This tool fits best alongside other PC Power Supplies & UPS options as a quick verification step. It helps you rule out power issues before swapping out components, saving time during troubleshooting. It is not a power source itself, so you must connect it to a working PSU to get readings.

Check before you buy

  • Confirm your PSU uses 20/24 pin ATX connectors.
  • Check if you need load testing beyond voltage checks.
  • Verify you have a multimeter for precise readings.
  • Ensure you have spare connectors for different PSU types.
