7. Troubleshooting
If you encounter issues during or after assembly, consider the following common solutions:
- No Power: Ensure the PSU is properly connected to the wall outlet and the motherboard. Check all power cables (24-pin, CPU, GPU) are securely seated.
- Fans Not Spinning/No ARGB: Verify that the fans are correctly connected to the ARGB fan hub and the hub is powered via SATA. Ensure the ARGB splitter cable is connected to a compatible motherboard header if you wish to control lighting via software.
- No Display: Confirm the graphics card is fully seated in its PCIe slot and power cables are connected. Ensure the monitor cable is plugged into the graphics card, not the motherboard's integrated graphics port (unless using integrated graphics).
- Loose Panels: Ensure the tool-free panels are properly aligned and pushed firmly into place until the fixing studs engage.
