• Environment: Operate the power supply in a clean, dry, and well-ventilated environment.

8. Troubleshooting

If you encounter issues with your power supply, consider the following troubleshooting steps:

• No Power:
  • Ensure the AC power cord is securely connected to both the power supply and the wall outlet.
  • Check that the power supply's main switch is in the 'ON' position.
  • Verify that the wall outlet is functional by plugging in another device.
  • Confirm all internal power cables (24-pin, CPU, PCIe) are correctly and firmly connected.
• System Instability/Crashes:
  • Ensure your system's power requirements do not exceed the 650W capacity of the PSU.
  • Check for proper ventilation within your PC case to prevent overheating of components, including the PSU.
  • Verify that all power connections to components are secure.
• Unusual Noise:
  • A slight fan noise is normal during operation. If the noise is excessive or unusual, ensure no cables are obstructing the fan.
  • If coil whine is present, it may be due to specific load conditions. While often harmless, if persistent and bothersome, contact support.
