8. Troubleshooting

If you encounter issues with your Apevia SFX-AP400W Power Supply, refer to the following common troubleshooting steps:

• No Power to System:
  • Ensure the AC power cord is securely plugged into both the PSU and the wall outlet.
  • Verify the power switch on the back of the PSU is in the 'I' (On) position.
  • Check all internal power connections (20+4pin, 4pin 12V, PCIe, SATA, Molex) to ensure they are firmly seated.
  • Test the wall outlet with another device to confirm it is supplying power.
• System Instability/Random Shutdowns:
  • This could indicate an overloaded or failing power supply. Ensure your system's power requirements do not exceed the PSU's 400W capacity.
  • Check for proper ventilation to prevent overheating, which can cause shutdowns.
• Unusual Noises (e.g., rattling, high-pitched whine):
  • A rattling noise might indicate a loose component or a fan issue. If the noise is persistent or severe, discontinue use and contact support.
  • A high-pitched whine (coil whine) can occur in some power supplies, especially under certain loads. While often not indicative of a fault, if it is excessively loud or new, monitor the PSU's performance.
• Burning Smell:
  • Immediately power off and unplug the system. Do not attempt to use the PSU again. Contact support.
