  • Clear digital LCD shows real-time 3.3V 5V 12V readings
  • Tests 20Pin and 24Pin ATX main power connectors
  • Includes SATA and 4Pin ports for drive and CPU power
  • Plug-and-play operation powered directly by the PSU under test

Professional PSU Diagnostic Tool

The SMUGDESK digital LCD ATX power supply tester is built for PC technicians, IT staff and DIY builders who need to verify desktop power supply health before fitting components. It replaces basic indicator lights with a clear screen that shows real-time voltage readings for every rail. The handheld unit draws operating power directly from the PSU under test, so no battery or external adapter is required.

20Pin 24Pin SATA 4Pin Coverage

The tester accepts 20Pin and 24Pin main motherboard connectors plus SATA and 4Pin CPU auxiliary ports in a single session. It displays 3.3V, 5V and 12V outputs simultaneously, making it easy to spot a rail that has drifted out of specification. The tool covers the standard ATX output loop but cannot measure -12V, -5V or 5VSB lines that some advanced diagnostics require.

Passive Cooling Silent Operation

Because the circuit is powered only by the supply being tested, the unit generates negligible heat and runs completely silently during use. The solid plastic shell protects the internal board during repeated bench work, and the compact form factor keeps the workspace clear. No fan, no active cooling and no separate power draw mean the tester adds zero load to the PSU under evaluation.

Questions about this item

Will the 24Pin and 20Pin connectors on this tester work with the older ATX power supply I still use?

Yes, it supports both 20Pin and 24Pin main motherboard interfaces, compatible with most ATX standard power supplies.

How can I confirm the tester is showing accurate voltage readings once I plug it in?

The digital LCD screen displays real-time voltage values for 3.3V, 5V, 12V and other output circuits so you can directly judge stability.

Does the package include cables for SATA and 4Pin ports, or must I buy them separately?

The tester has built-in SATA and 4Pin connector ports; you plug the power supply cables directly into the unit, no extra cables needed.
