6. Operating the Power Supply

Once installed, operating your EVGA Supernova 850 G5 is straightforward:

• Power On: Connect the AC power cord to the power supply and a wall outlet. Flip the main power switch on the back of the PSU to the 'ON' position.
• ECO Mode: The EVGA Supernova 850 G5 features an ECO mode, controlled by a switch on the rear panel. When ECO mode is enabled, the power supply fan will remain off during low to moderate loads, providing ultra-quiet operation. The fan will automatically activate when the load increases or internal temperatures rise. Disabling ECO mode will cause the fan to spin continuously based on temperature.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply:

• Dust Cleaning: Periodically clean dust from the power supply's fan and ventilation grilles using compressed air. Ensure the system is powered off and unplugged before cleaning.
• Internal Components: Do not attempt to clean or service internal components. The unit is sealed, and opening it can be dangerous and will void the warranty.
• Environment: Operate the power supply in a clean, dry, and well-ventilated environment to prevent dust buildup and overheating.

8. Troubleshooting

If you encounter issues with your EVGA Supernova 850 G5, consider the following 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 testing it with another device.
  • Confirm all modular cables are correctly seated in both the PSU and the computer components.
• System Instability/Crashes:
  • Ensure all power connections to the motherboard, CPU, and graphics card(s) are secure.
  • If you have recently added new components, ensure your total power draw does not exceed the PSU's capacity.
  • Check for proper ventilation within your computer case to prevent overheating.
• Fan Not Spinning (ECO Mode): If ECO mode is enabled, the fan is designed to remain off under low loads. This is normal operation. The fan will activate automatically when needed. If the fan does not spin under heavy load with ECO mode disabled, contact support.

If issues persist after performing these checks, please contact EVGA customer support.
