Power supply tester

The Vszerda Digital LCD Power Supply Tester checks ATX, BTX and ITX power supplies through a 20 or 24 pin connector. It reads +12V, -12V, +5V, -5V, +3.3V, +5V standby and power good signals. No batteries are required for operation. The tool suits hobbyists and technicians who need a quick functional verification before installing a unit.

Sustained load behaviour

The tester draws power directly from the supply under test so it remains active for as long as the unit stays on. Voltage readings on the LCD update continuously while the supply delivers power to the 20/24 pin, 4 pin, 6 pin, 8 pin, SATA, floppy and other connectors. A steady DuDu tone sounds if all monitored rails stay within normal limits during extended runs.

Thermals noise and power

The device has no fan or active cooling; it relies on passive heat dissipation from its own circuitry. Audible feedback is limited to the built-in buzzer that signals normal or fault conditions. Because it consumes only the small current needed for the LCD and logic, it adds negligible load to the supply being tested.

Questions about this item

How much power does the tester draw while checking a supply all day?

The tester is powered directly from the 20/24-pin ATX connector of the supply under test and needs no separate battery or mains connection.

What connectors must my power supply already have for this tester to work?

Your supply needs a 20/24-pin ATX connector plus any of the 4-pin P4, 8-pin EPS, 6-pin PCIe, SATA, floppy or Molex leads you want to verify.

Will the tester read voltages correctly on an older ATX supply I have kept?

Yes, it supports ATX, BTX and ITX compliant supplies and measures +12V, -12V, +5V, -5V, +3.3V, +5VSB and power-good on any compatible unit.
