Compact PSU Diagnostic Tool

The ETopSell Digital LCD Power Supply Tester checks ATX, BTX and ITX units through a 20/24 pin connector. It reads +12V, -12V, +5V, -5V, +3.3V, +5V standby and power-good signals on a built-in display. The handheld device weighs 3.1 oz and measures 3.8 by 2.5 by 0.8 inches.

Build Integration Requirements

Connect the 20/24 pin ATX lead plus any 4 pin P4, 6 pin PCI-Express or 8 pin dual-CPU cables directly to the tester. Floppy, HDD, CDROM and SATA power connectors are also supported for peripheral rail verification. No external power source or software is needed; the unit draws operating power from the supply under test.

Target Users And Limitations

Suits technicians and builders who need quick go/no-go voltage confirmation on desktop power supplies. Not intended for load testing, ripple measurement or server-grade redundant PSU validation. Buyers who require automated logging, programmable loads or high-current stress capability should look at dedicated bench equipment.

Questions about this item

How many voltage rails does the LCD display monitor at once?

The tester checks +12V, -12V, +5V, -5V, +3.3V, +5V standby and 12V power-good signals simultaneously.

Does the unit become noisy or hot during extended testing sessions?

It has no fan or active cooling; the LCD and buzzer draw minimal power so heat and noise stay negligible.

Which power-supply connectors must already be present on the PSU for this tester to work?

The PSU needs a 20/24-pin ATX header plus 4-pin P4, 6-pin PCIe or 8-pin EPS connectors to test all rails.
