SUIUBUY 20/24 Pin LCD Power Supply Tester

This device checks ATX, BTX and ITX power supplies by connecting their 24-pin, P4, P6 or P8 connectors to the tester. An LCD shows the status of each voltage rail while an audible buzzer signals normal or abnormal readings. It is built for hobbyists and technicians who need a quick functional verification of a PSU.

Thermals, noise and power draw

The tester draws its operating power directly from the supply under test, so it adds no extra load to the bench. It runs silently apart from the built-in buzzer that emits a short tone for normal voltage and a sustained tone when a rail is missing or out of range. No fan or active cooling is present on the unit.

Connectors and what they enable

Included jacks cover Floppy, HDD, CD-ROM, SATA, 4-pin (P4), 8-pin (Dual-CPU) and 6-pin (PCI-Express) power leads, letting you test every major output of a desktop PSU in one session. Builders who need to validate server-grade EPS12V or newer 12VHPWR cables cannot do so with this tester.

Questions about this item

How do I connect the 24-pin ATX and CPU power cables to the tester for the first check?

Plug the PSU 24-pin and P4, P6 or P8 connectors into the matching jacks on the tester, then power on the supply.

What upkeep does the LCD voltage tester require over time?

No periodic maintenance is needed; keep the connector pins clean and store the unit dry.

At what point does the tester signal a fault during a prolonged load test?

A continuous "DuDu" buzzer and flickering voltage or PG readings indicate a detected voltage outside normal limits.
