4. Setup and Installation

Follow these steps to install your SilverStone SST-AD120-DC power supply unit:

1. Prepare Your System: Ensure your computer system is completely powered off and disconnected from the AC power outlet. Open your computer case to access the motherboard and drive bays.
2. Install the DC-DC Power Board: Mount the 120W DC-DC power board securely within your computer case. The Mylar insulation design facilitates easy installation. Ensure it is positioned to allow for proper cable routing and airflow.
3. Connect Main Power (ATX 20+4-pin): Connect the 20+4-pin main power cable from the DC-DC board to the corresponding ATX power connector on your motherboard. Ensure the connection is firm and fully seated.
4. Connect CPU Power (4+4-pin): Connect the 4+4-pin CPU power cable to the CPU power connector on your motherboard. This is typically located near the CPU socket.
5. Connect Peripheral Power (4-pin): If your system requires it, connect the Peripheral 4-pin power cable to devices such as case fans or older drives.
6. Connect SATA Power: Connect the SATA power cables to your SATA hard drives, solid-state drives, or optical drives. The kit includes cables with multiple SATA connectors.
7. Connect AC to DC Adapter: Plug the DC output cable from the 120W AC to DC power adapter into the DC input port on the SST-AD120-DC power board.
8. Secure Cables: Route and secure all cables to ensure they do not obstruct airflow or interfere with other components.
9. Close Case and Connect AC Power: Close your computer case. Plug the AC power cord into the 120W AC to DC power adapter, and then plug the adapter into a grounded AC wall outlet.

6. Maintenance

The SilverStone SST-AD120-DC is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:

• Keep Clean: Periodically clean the interior of your computer case to prevent dust buildup on the power board and other components. Use compressed air to gently remove dust.
• Ensure Ventilation: Make sure your computer case has adequate airflow to prevent overheating. Do not block ventilation openings.
• No User-Serviceable Parts: The SST-AD120-DC contains no user-serviceable parts. Do not attempt to open or repair the unit, as this will void the warranty and may pose a safety risk.

7. Troubleshooting

If you encounter issues with your SST-AD120-DC, refer to the following troubleshooting steps:

• No Power:
  • Check if the AC power cord is securely plugged into the wall outlet and the AC to DC adapter.
  • Verify that the DC output cable from the adapter is firmly connected to the DC-DC power board.
  • Ensure all power cables (20+4-pin, 4+4-pin CPU, SATA, Peripheral) are correctly and securely connected to the motherboard and components.
  • Test the AC outlet with another device to confirm it is functional.
• System Instability or Random Shutdowns:
  • Confirm that your system's total power consumption does not exceed the 120W output capacity of the SST-AD120-DC.
  • Check for any loose cable connections inside the computer case.
  • Ensure adequate ventilation to prevent overheating of components.
• Protection Circuitry Activation:
  • The SST-AD120-DC has built-in multiple protection circuits. If the system unexpectedly shuts down, disconnect the AC power, wait a few minutes, and then check for any short circuits or faulty components before reconnecting power.
