- PCIe Power: Connect to your graphics card(s) as required.
- SATA Power: Connect to your storage drives.
- Peripheral/Molex Power: Connect to any other components requiring this type of power.
3.6 Front Panel Connections
Connect the front panel cables to the corresponding headers on your motherboard:
- USB 3.2 Type-C: Connect the internal USB-C header cable to your motherboard's USB 3.2 Gen2 Type-C header.
- USB 3.0: Connect the internal USB 3.0 header cable to your motherboard's USB 3.0 header.

3.7 Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to manage cables. Proper cable management improves airflow and aesthetics.
- Route main power cables (24-pin, EPS) through the largest cutouts.
- Use cable ties or Velcro straps (included in accessory box) to bundle and secure cables.
- Ensure no cables obstruct fan blades or airflow paths.
4. Operating Instructions
4.1 Powering On Your System
- Once all components are installed and cables connected, replace the tempered glass side panel.
- Connect the AC power cord to the PSU and then to a wall outlet.
- Flip the power switch on the back of the PSU to the 'ON' position.
- Press the power button on the front panel of your case.
4.2 ARGB Lighting Control
The BitFenix AL118 features Addressable RGB (ARGB) lighting. The control method depends on how the ARGB components are connected:
- Motherboard Sync: If the ARGB cables are connected to a compatible 3-pin 5V ARGB header on your motherboard, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync).
- Integrated Controller: If the case includes a built-in ARGB controller (often connected to a reset button or dedicated ARGB button), you can cycle through pre-programmed lighting modes by pressing that button. Refer to the specific controller's instructions if applicable.
5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC components.
- Dust Filters: The case is equipped with dust filters (e.g., top, front, bottom). Regularly remove and clean these filters with water and mild soap, or by vacuuming/brushing them. Ensure they are completely dry before re-installing.
- Interior Cleaning: Periodically use compressed air to blow dust out of the case interior, especially from fan blades, heatsinks, and vents. Ensure the system is powered off and unplugged before cleaning.
- Tempered Glass: Clean the tempered glass panel with a microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals.
6. Troubleshooting
If you encounter issues with your PC build, refer to the following common troubleshooting steps:
- No Power / System Not Starting:
- Ensure the PSU power switch is in the 'ON' position.
- Check that the AC power cord is securely connected to both the PSU and the wall outlet.
- Verify all PSU cables (24-pin, EPS, PCIe) are firmly connected to the motherboard and components.
- Confirm the front panel power switch cable is correctly connected to the motherboard header.
- No Display Output:
- Ensure your monitor is connected to the graphics card (GPU) output, not the motherboard's integrated graphics output (unless you are using integrated graphics).
- Reseat the graphics card in its PCIe slot.
- Check that the GPU's power cables are securely connected.
- Fans Not Spinning / ARGB Not Working:
- Verify that all fan power cables are connected to the motherboard fan headers or a fan controller.
- Check ARGB cables are connected to a compatible 3-pin 5V ARGB header on the motherboard or an ARGB controller.
- If using motherboard software, ensure it is installed and configured correctly.
- Overheating:
- Ensure all case fans are spinning and oriented correctly for optimal airflow (intake/exhaust).
- Clean dust filters and case interior as described in the Maintenance section.
- Verify CPU cooler and GPU cooler are properly installed and functioning.
