4. Setup Instructions
To begin testing your power supply, follow these steps:
- Ensure the power supply unit is turned off and unplugged from the wall outlet.
- Connect the main 20/24-pin ATX connector from your power supply to the corresponding port on the tester.
- For comprehensive testing, also connect the CPU 4/8-pin connector to the tester.
- You may also connect other peripheral connectors such as PCI-E (6/8-pin), SATA, or IDE/HDD to their respective ports on the tester.
- Once all desired connectors are securely attached to the tester, plug in and power on your power supply unit. The tester will automatically begin displaying voltage readings.

5. Operating Instructions
5.1 Reading the LCD Display
Upon powering on the connected power supply, the LCD display will illuminate and show various voltage values and the Power Good (PG) signal. Each value represents a specific rail of the power supply.
Image: A detailed explanation of the LCD screen, indicating rated voltage, detected voltage, and the PG power signal. Includes a table of ATX power supply voltage parameters.
- Voltage Readings: The display shows voltages for +12V, -12V, +5V, +3.3V, +5VSB (Standby Voltage), and +12V2 (if applicable).
- PG (Power Good) Signal: This value indicates the time it takes for the power supply to stabilize its output voltages after being turned on. A normal PG value is typically between 100ms and 500ms.
5.2 Interpreting Alarms
The tester is equipped with an automatic alarm system to alert you to potential issues:
- Buzzer Sound: If any voltage reading is outside the acceptable range or if the PG value is abnormal, the tester will emit a continuous buzzer sound.
- Flashing Values: The specific voltage value or PG value that is out of range will flash on the LCD display, indicating the problematic rail.
- "LL" Display: If the display shows "LL" for a voltage rail, it indicates a power failure for that group of voltage or that the connector is not properly plugged in.

6. Troubleshooting
If the tester indicates a fault, consider the following:
- Buzzer Alarm / Flashing Values: This indicates a voltage output or PG signal outside the normal operating parameters. Refer to the Specifications section for acceptable voltage ranges. A consistent alarm suggests a faulty power supply.
- "LL" on Display: This means the voltage for that specific rail is not detected or the connector is not properly inserted. Ensure all connectors are firmly seated. For P4/P6/P8/SATA/IDE connectors, note that their voltage values will only display on the LCD if the main 20/24-pin ATX connector is also connected. Otherwise, they may only show a light indicator.
- No Display: Ensure the power supply is properly connected and powered on. Check the power supply itself for any signs of failure.
