3. Setup and Installation
This section provides general guidance for installing your Vetroo 850W Power Supply. For detailed, step-by-step instructions, please refer to the official Installation Manual (PDF).
3.1 Physical Installation
- Prepare Your PC Case: Ensure your PC case has adequate space for the power supply unit. The Vetroo 850W PSU has dimensions of approximately 5.9 x 5.5 x 3.4 inches.
- Mount the PSU: Carefully slide the power supply into its designated bay in your PC case. Secure it using the provided mounting screws.
- Connect Essential Cables:
- Connect the 24-pin ATX cable to your motherboard.
- Connect the 8-pin (4+4) CPU power cable(s) to your motherboard.
- For graphics cards, connect the appropriate PCIe 8-pin (6+2) or the new PCIe 5.1 16 (12+4)-pin cable. Ensure your GPU is compatible with the connected cable type.
- Connect Peripheral Cables: Attach SATA cables for SSDs, HDDs, and optical drives, and Molex cables for other peripherals as needed. The fully modular design allows you to connect only the cables required, reducing cable clutter and improving airflow.
- Cable Management: Route cables neatly behind the motherboard tray or in designated cable management areas to optimize airflow and aesthetics. Use the included cable ties or Velcro straps.
- Connect AC Power: Once all internal connections are secure, connect the AC power cord to the power supply and then to a wall outlet or surge protector.

4. Operating Instructions
The Vetroo 850W Power Supply is designed for straightforward operation. After successful installation, follow these steps:
- Power Switch: Locate the main power switch on the back of the power supply unit. Ensure it is in the 'ON' (I) position before powering on your computer.
- ECO Mode Switch: The power supply features an ECO mode switch.
- ECO ON: In this mode, the fan will stop spinning under low load conditions (typically below 50% load) to provide silent operation. The fan will automatically activate when the load increases.
- ECO OFF: In this mode, the fan will spin continuously regardless of the load, providing constant cooling.
- System Power On: Once the power supply is connected and switched on, you can power on your computer system using the case's power button.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Vetroo 850W Power Supply.
- Dust Removal: Periodically clean the power supply's fan and ventilation grilles to prevent dust buildup, which can impede airflow and lead to overheating. Use compressed air to gently blow dust out of the unit. Ensure the power supply is disconnected from the wall outlet before cleaning.
- Fan Inspection: The 120mm FDB fan is designed for quiet and efficient cooling. If you notice unusual noises or reduced fan performance, ensure there are no obstructions.
- Cable Connections: Occasionally check all modular cable connections to ensure they are securely seated. Loose connections can lead to instability or component damage.
- Operating Environment: Ensure the power supply operates in a well-ventilated area, free from excessive heat, humidity, and direct sunlight.

6. Troubleshooting
If you encounter issues with your Vetroo 850W Power Supply, refer to the following common troubleshooting steps:
- No Power to System:
- Ensure the AC power cord is securely connected to both the power supply and the wall outlet.
- Verify the main power switch on the PSU is in the 'ON' (I) position.
- Check all modular cables are firmly connected to both the power supply and the respective components (motherboard, CPU, GPU).
- Test the wall outlet with another device to ensure it has power.
- Fan Not Spinning (in ECO Mode):
- This is normal behavior if the ECO mode is enabled and the system load is low. The fan will activate automatically when the load increases.
- If you prefer continuous fan operation, switch the ECO mode to 'OFF'.
- System Instability or Crashes:
- Ensure your system's power requirements do not exceed the 850W capacity of the PSU.
- Check for loose cable connections.
- The power supply includes multiple protection features (OVP, OCP, OPP, SCP, UVP, OTP) to prevent damage. If the PSU shuts down unexpectedly, it might be due to one of these protections being triggered. Disconnect power, wait a few minutes, and re-attempt. If the issue persists, consult a professional.
- Unusual Noises:
- Ensure no cables or foreign objects are obstructing the fan.
- If the noise persists and is not related to normal fan operation, contact customer support.
