8. Troubleshooting
If you encounter issues with your power supply, consider the following:
- No Power:
- Check if the AC power cord is securely connected to both the power supply and the wall outlet.
- Ensure the power switch on the back of the PSU is in the 'ON' position.
- Verify that all modular cables (especially the 24-pin motherboard and CPU cables) are firmly seated.
- Test the wall outlet with another device to confirm it has power.
- System Instability/Crashes:
- Ensure your power supply wattage is sufficient for all your components.
- Check for loose cable connections.
- Monitor system temperatures to rule out overheating of other components.
- Unusual Noises:
- A slight fan noise is normal under load. If you hear grinding or excessive noise, ensure no cables are obstructing the fan.
- If coil whine is present and persistent, it may indicate an issue. Contact support if it's disruptive.
If problems persist after following these steps, contact Seasonic customer support.
