3. Setup and Installation
3.1 Safety Precautions
- Ensure your system is completely powered off and unplugged from the wall outlet before installation.
- Discharge any static electricity by touching a grounded metal object before handling components.
- Do not open the power supply unit. High voltages are present inside.
3.2 Installation Steps
- Mount the Power Supply: Secure the ENERMAX Revolution III 850W PSU into the designated power supply bay of your PC case using the provided screws.
- Connect Motherboard Power: Connect the 24-pin ATX motherboard cable to the corresponding port on your motherboard and the PSU.
- Connect CPU Power: Connect the 8-pin (4+4 pin) CPU power cable(s) to your motherboard and the PSU.
- Connect GPU Power: For graphics cards requiring a 12V-2x6 connector, use the native 600W cable. For other GPUs, use the appropriate PCIe (6+2 pin) cables. Ensure all connections are secure.
- Connect Peripherals: Connect SATA power cables to your storage drives (HDDs, SSDs) and Molex cables to any other peripherals as needed.
- Cable Management: Utilize the fully modular design and mesh-sleeved cables to organize your cables for optimal airflow and a clean build.
- Power On: Once all connections are secure, connect the AC power cord to the PSU and a wall outlet. Flip the power switch on the PSU to the 'On' position.

4. Operating Instructions
After successful installation, your ENERMAX Revolution III 850W Power Supply is ready for operation. The unit is designed for continuous, stable power delivery.
- Power On/Off: Use the main power switch located on the rear of the PSU to turn the unit on or off. Always ensure the system is properly shut down via the operating system before switching off the PSU.
- Fan Operation: The 120mm FDB fan operates intelligently, adjusting its speed based on the power supply's temperature and load. This ensures optimal cooling while maintaining quiet operation.
5. Maintenance
To ensure the longevity and optimal performance of your power supply, periodic maintenance is recommended.
- Cleaning: Regularly clean the fan grill and ventilation openings of the power supply to prevent dust buildup. Use compressed air or a soft brush. Ensure the system is powered off and unplugged before cleaning.
- Cable Inspection: Periodically check all modular cable connections to ensure they are seated firmly.
- Environment: Operate the power supply in a well-ventilated area, away from excessive heat, humidity, or dust.
6. Troubleshooting
If you encounter issues with your power supply, refer to the following common troubleshooting steps:
- No Power:
- Check if the AC power cord is securely connected to both the PSU and the wall outlet.
- Ensure the main power switch on the PSU is in the 'On' position.
- Verify that the wall outlet is functional by plugging in another device.
- System Instability/Random Shutdowns:
- Ensure all modular cables are correctly and firmly seated in both the PSU and the components.
- Confirm that your system's power requirements do not exceed the 850W capacity of the PSU.
- The PSU's built-in protection circuitries (OCP, OVP, UVP, OPP, SCP, OTP) may trigger a shutdown to protect components if an anomaly is detected. If this occurs, identify and resolve the underlying issue (e.g., short circuit, excessive load).
- Excessive Fan Noise:
- Clean the fan and ventilation areas to remove any dust buildup.
- Ensure the PSU is operating within its normal temperature range. High temperatures can cause the fan to spin faster.
If problems persist after following these steps, please contact customer support.
