Compact ATX PSU Tester

This handheld device checks 20/24-pin ATX, BTX and ITX power supplies through a built-in LCD. It reads +12V, -12V, +5V, -5V, +3.3V, +5V standby and the 12V Power Good signal. A short audible beep confirms normal output, while a long tone flags missing or out-of-range voltages. The unit suits hobbyists and technicians who need a quick functional check without a full bench setup.

Verify connector match before use

Ensure the supply under test exposes a 20/24-pin main connector plus any required 4-pin, 6-pin or 8-pin auxiliary plugs. The tester provides matching jacks for Floppy, HDD, CDROM, SATA, 4-pin (P4), 8-pin (Dual-CPU) and 6-pin (PCI-Express) cables. No external power source is needed; the unit draws operating power directly from the supply being tested.

LCD readout replaces multimeter probes

The integrated display shows each rail voltage in real time, removing the need to back-probe molex or SATA connectors manually. Buzzer feedback lets you keep eyes on the screen while listening for fault tones. This tool does not load the supply, so it cannot verify regulation under load or detect ripple; buyers who need loaded stress tests or waveform analysis will require separate equipment.

Perguntas sobre este artigo

Does the package include cables for the 4-pin, 6-pin and 8-pin connectors or must they be sourced separately?

The tester has built-in jacks for 20/24-pin ATX, 4-pin P4, 6-pin PCI-Express and 8-pin dual-CPU connectors, plus SATA, floppy and HDD headers, so no extra cables are required.

Should I pick a different model if I only need to test SATA drives?

This unit tests the full ATX rail set (+12V, -12V, +5V, -5V, +3.3V, +5VSB and Power Good) alongside SATA, floppy and legacy headers, so it covers SATA and much more in one device.

What does the LCD actually tell me when the PSU is running?

The display shows the real-time voltage on each rail and the Power Good signal; a steady reading means the output is within normal limits, while a flashing value or long buzzer flags a fault.
