トラブルシューティング
If you encounter issues with your Enermax DIGIFANLESS 550W PSU, refer to the following common troubleshooting steps:
- 電源なし:
- Ensure the main power cable is securely connected to both the PSU and the wall outlet.
- Verify the PSU's power switch on the rear is in the 'ON' position.
- PSU およびコンポーネント (マザーボード、CPU、GPU) へのすべてのモジュラー ケーブル接続を確認します。
- システムの不安定性/クラッシュ:
- Use the ZDPMS software to monitor voltage and temperature. High temperatures or unstable voltages can indicate an issue.
- Ensure your system's power draw does not exceed the PSU's 550W capacity.
- Check for any warning messages from the ZDPMS software (e.g., Over Temperature, Over Voltage, Over Current).
- ZDPMS Software Not Detecting PSU:
- Verify the USB cable connecting the PSU to the motherboard is correctly installed.
- Ensure the ZDPMS software is installed correctly and is the latest version.
- コンピュータを再起動してみてください。
