6. Troubleshooting
This section addresses common issues you might encounter during assembly or operation.
6.1. System Not Powering On
- Ensure the PSU is properly connected to the wall outlet and the power switch on the PSU is in the 'ON' position.
- Verify that the 24-pin ATX power cable and the 8-pin CPU power cable are securely connected to the motherboard.
- Check that the front panel power button cable is correctly connected to the motherboard's front panel header.
6.2. Fans Not Spinning or ARGB Not Working
- Confirm that the fan power cables are connected to the appropriate fan headers on the motherboard or a fan controller.
- Ensure ARGB cables are connected to a compatible 3-pin 5V ARGB header on the motherboard or an ARGB controller.
- If installing additional fans, particularly in tight spaces like the bottom of the case, ensure sufficient clearance for tools during installation to avoid damage or improper seating.
6.3. Difficulty Removing Panels
- For the tempered glass side panel, ensure all four retaining screws (two top, two bottom) are fully loosened before attempting to lift or slide the panel.
- For other panels, check for thumbscrews or clips that need to be disengaged. Refer to the exploded view diagram (Image 3.1) for guidance on panel attachment points.
