The EVGA SuperNOVA 850W power supply unit (PSU) is a popular choice among PC builders for its reliability and high wattage. Proper mounting of the PSU is essential for optimal performance, safety, and ease of maintenance. Follow these best practices to ensure a secure and efficient installation.

Preparation Before Mounting

Before beginning the mounting process, gather all necessary tools and components. Ensure your workspace is clean and static-free. Verify that the case supports an ATX power supply of 850W capacity and has adequate ventilation.

Choosing the Right Location

Select a mounting position that allows for proper airflow and cable management. Typically, the PSU is installed at the bottom rear of the case. Confirm that there is enough clearance for the power cables and that ventilation holes align with the PSU fan.

Aligning the PSU

Position the PSU so that the fan faces the vented area of the case, usually downward. This promotes better airflow and dust filtration. Ensure the screw holes on the PSU align with those on the case.

Securing the PSU

Insert screws through the PSU mounting holes into the case. Tighten them evenly to avoid stress on the PSU or case. Do not overtighten, as this could damage the components.

Connecting Cables Properly

After mounting, connect the power cables to your components. Use the modular connectors on the EVGA SuperNOVA 850W to reduce clutter. Ensure all connections are secure and correctly oriented.

Cable Management Tips

  • Route cables behind the motherboard tray if possible.
  • Use cable ties or Velcro straps to tidy loose cables.
  • Avoid blocking airflow paths with cables.

Final Checks and Testing

Once everything is connected, double-check all screws and cables. Power on the system to verify the PSU functions correctly. Monitor for any unusual noises or overheating during initial operation.

Maintenance and Safety

Periodically inspect the mounting screws and cable connections. Keep the PSU and surrounding area clean from dust. Always disconnect power before performing maintenance to ensure safety.
