Operating the PC Case
Powering On
Once all components are installed and cables are connected, replace the side panels. Connect your monitor, keyboard, mouse, and power cable to the PC. Press the power button on the front panel of the case to turn on your system.
ARGB Fan Control
The XPG INVADER X MINI comes with five pre-installed ARGB fans. These fans can be controlled via your motherboard's ARGB software (if compatible) or a dedicated ARGB controller (if included or purchased separately). Refer to your motherboard manual or ARGB controller instructions for specific lighting effects and synchronization.
Maintenance
Dust Filter Cleaning
The case is equipped with dust filters to prevent dust buildup inside. Regularly clean these filters (typically located at the top, front, and bottom) by removing them and gently brushing or washing them with water. Ensure they are completely dry before re-installing.
General Cleaning
Use a soft, damp cloth to wipe down the exterior of the case. Avoid abrasive cleaners or solvents that may damage the finish or tempered glass panels.
Troubleshooting
- System Not Powering On: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected. Check the power switch connection to the motherboard. Verify the PSU is switched on.
- Fans Not Spinning/ARGB Not Lighting Up: Check fan power connections to the motherboard or fan controller. Ensure ARGB headers are correctly connected and software is configured.
- No Display Output: Confirm the graphics card is properly seated in its PCIe slot and has adequate power. Ensure the monitor cable is connected to the graphics card, not the motherboard's integrated graphics ports (unless using integrated graphics).
- Overheating: Verify all fans are spinning correctly and are oriented for optimal airflow (intake/exhaust). Ensure CPU cooler and GPU fans are functioning. Clean dust filters.
