5. Setup & Installation
Follow these steps to install your Thermaltake Smart BX1 650W Power Supply:
- Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your PC case to access the power supply mounting area.
- Mount the Power Supply: Carefully place the Thermaltake Smart BX1 PSU into the designated power supply bay in your PC case. Secure it with the provided mounting screws.
- Connect Main Power (24-pin ATX): Connect the large 24-pin ATX cable from the PSU to the corresponding port on your motherboard. Ensure it clicks securely into place.
- Connect CPU Power (8-pin EPS/ATX12V): Connect the 8-pin (4+4 pin split) CPU power cable to the CPU power connector on your motherboard. If your motherboard uses an 8-pin connector, use both halves. If it uses a 4-pin connector, use only one half.
- Connect Graphics Card Power (PCI-E): For your graphics card, use the PCI-E 6+2pin connectors. Connect the appropriate number of connectors to your graphics card. Avoid using a single cable for multiple high-power graphics cards if separate cables are available.
- Connect SATA Devices: Use the SATA power cables to connect your storage drives (HDDs, SSDs) and optical drives.
- Connect Peripheral Devices (Molex): Use the Molex connectors for any other peripheral devices that require them, such as case fans or older components.
- Cable Management: Utilize the flat design of the cables to route them neatly behind the motherboard tray or through designated channels in your case. This improves airflow and aesthetics.
- Close Case and Power On: Once all connections are secure, close your PC case, plug the AC power cord into the PSU and a wall outlet, and power on your system.

6. Operating Instructions
The Thermaltake Smart BX1 650W Power Supply operates automatically once installed and connected correctly. The 12cm hydraulic bearing fan will adjust its speed based on the power supply's temperature and load to maintain optimal cooling while minimizing noise. No user intervention is typically required for its operation.
7. Maintenance
To ensure the longevity and optimal performance of your power supply, consider the following maintenance tips:
- Keep it Clean: Periodically clean the exterior of the power supply and the fan grille to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Ensure Proper Airflow: Make sure your PC case has adequate airflow. Avoid blocking the intake or exhaust vents of the power supply.
- Avoid Overloading: Do not exceed the rated wattage of the power supply. Overloading can lead to instability and premature failure.
- Regular Checks: Occasionally check cable connections to ensure they are secure.
8. Troubleshooting
If you encounter issues with your power supply, try the following steps:
- No Power:
- Ensure the AC power cord is securely plugged into both the power supply and a working wall outlet.
- Check the power switch on the back of the PSU; it should be in the 'ON' position.
- Verify all internal power connections (24-pin ATX, 8-pin CPU, PCI-E) are firmly seated.
- System Instability/Random Shutdowns:
- This could indicate an overloaded PSU or a component issue. Ensure your system's power requirements do not exceed 650W.
- Check for proper ventilation and ensure the PSU fan is spinning freely.
- If the issue persists, test components individually or consult a professional.
- Excessive Noise:
- Ensure no cables or obstructions are interfering with the fan blades.
- Clean any dust buildup from the fan and vents.
If these steps do not resolve your issue, please contact Thermaltake customer support for further assistance.
