3. Setup

The ASHATA LCD Power Supply Tester is designed for straightforward setup. Follow these steps to prepare the device for testing:

  1. Ensure the power supply unit (PSU) you intend to test is disconnected from the computer system and any power source.
  2. Identify the main 20-pin or 24-pin ATX power connector from your PSU.
  3. Locate the corresponding 20-pin or 24-pin input on the power supply tester.
  4. Carefully insert the PSU's main ATX connector into the tester's input. Ensure a firm and secure connection.
  5. For additional tests, connect other PSU cables (e.g., SATA, 4-pin/8-pin CPU, 6-pin/8-pin PCIe, Molex, Floppy) to their respective ports on the tester.

4. Operating Instructions

Once the power supply is connected to the tester, you can begin the testing process:

  1. After connecting the PSU to the tester, power on the PSU. The tester will automatically activate.
  2. Observe the LCD display. It will show real-time voltage readings for +12V, -12V, +5V, -5V, +3.3V, 5VSB (Standby Voltage), and PG (Power Good signal).
  3. The green indicator lights (+12V, +3.3V, +5V) on the side of the tester will illuminate if these voltages are present and within acceptable limits.
  4. Listen for any audible alarms. If the tester detects voltage parameters outside the normal range, a buzzer will sound, and the abnormal parameters on the LCD screen will flash. This indicates a potential issue with the power supply.
  5. Refer to the ATX Power Supply voltage requirements table below for standard voltage ranges.

5. Maintenance

To ensure the longevity and accurate performance of your ASHATA LCD Power Supply Tester, follow these simple maintenance guidelines:

6. Troubleshooting

If you encounter issues while using your ASHATA LCD Power Supply Tester, refer to the following common troubleshooting steps:

ProblemPossible CauseSolution
LCD Screen is BlankPower supply not connected or not powered on.
Faulty power supply.
Ensure the 20/24-pin ATX connector is fully inserted and the PSU is powered on.
Test with a known good power supply if available.
Buzzer Alarm Sounds / Flashing ReadingsVoltage readings are outside acceptable ATX specifications.This indicates a potential fault with the power supply. Refer to the "ATX Power Supply Voltage Requirements" table in Section 4. Consider replacing the power supply if readings are consistently out of range.
Incorrect ReadingsLoose connection.
Tester malfunction.
Ensure all connectors are securely seated.
If the issue persists, contact customer support.
Green LEDs Not Lighting UpMissing or out-of-spec voltage on the corresponding rail.Check the LCD display for specific voltage readings. If a voltage is too low or absent, the PSU may be faulty.
