ATX Power Supply Tester

This myVolts unit checks ATX, ITX and BTX power supplies through 20-pin, 24-pin, 4-pin, 6-pin, 8-pin, SATA and IDE connectors. The 1.8-inch LCD shows each rail voltage with 0.01 V resolution. It is aimed at system builders and repair technicians who need quick pass-or-fail verification.

Aluminium Enclosure Thermal Behaviour

The aluminium alloy housing conducts heat away from the internal circuitry during normal operation. No active cooling is fitted, so the tester runs silently. Power is drawn solely from the supply under test via the 20/24-pin connection; no battery is required.

Bundled Accessories and Software Impact

A protective film covers the LCD screen and should be removed before first use. No software, drivers or calibration tools are included. The tester does not support hot-plug operation; all connectors must be seated before the supply is switched on.

Questions about this item

How do I install the 20/24-pin tester and what step causes the LL alarm?

Connect the 20-pin or 24-pin ATX cable plus the 4/6/8-pin CPU cable to the matching jacks; if the CPU cable is missing the LCD shows LL and sounds an alarm.

What maintenance or replacement will this tester need later?

The unit draws power from the 20/24-pin connector and has no battery, so no periodic battery change is required.

What limit appears first during sustained testing?

The LCD reads voltages to ±0.01 V accuracy; prolonged loads that push any rail outside normal range trigger a continuous buzzer and flashing display.
