2. Підключення модульних кабелів
The DIGIFANLESS 550W features a full modular design, allowing you to connect only the cables necessary for your system. This improves airflow and cable management.
- 24-контактний кабель материнської плати ATX: Підключіть цей кабель до основного роз'єму живлення на материнській платі.
- CPU (EPS/ATX 4+4-pin) Cable: Connect to the CPU power connector on your motherboard. Modern motherboards may require an 8-pin connector.
- PCI-E (6+2-pin) Cables: Connect these to your graphics card(s). Ensure you use enough connectors for your specific GPU.
- Кабелі живлення SATA: Підключення до пристроїв SATA, таких як SSD, HDD та оптичні приводи.
- Периферійні кабелі (Molex): За потреби підключіть старі периферійні пристрої або вентилятори корпусу.
- USB-кабель: Connect the provided USB cable from the PSU to an available USB header on your motherboard for ZDPMS software functionality.
Ensure all cables are securely seated. Improper connections can lead to system instability or damage.

Усунення несправностей
If you encounter issues with your Enermax DIGIFANLESS 550W PSU, refer to the following common troubleshooting steps:
- Немає живлення:
- 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.
- Перевірте всі кабельні з'єднання модулів з блоком живлення та компонентами (материнська плата, процесор, відеокарта).
- Нестабільність/збої системи:
- 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.
- Спробуйте перезавантажити комп'ютер.
If problems persist after following these steps, contact Enermax customer support for further assistance.
