5. Instrucións de funcionamento
The Rosewill CMG5 1000W Power Supply is designed for reliable and efficient operation.
Eco Silent Mode:
- The power supply features an "ECO" mode switch located on the rear panel.
- When the ECO mode is ON, the 120mm Fluid Dynamic Bearing (FDB) fan will operate in a semi-fanless mode. The fan will remain off under low to moderate loads, providing silent operation. It will automatically spin up when the load increases to maintain optimal temperatures.
- When the ECO mode is DESACTIVADO, the fan will operate continuously, adjusting its speed based on the internal temperature and load.
- Choose the mode that best suits your preference for noise levels and cooling performance.
Power Excursion Capabilities:
This power supply is designed to handle power excursions up to 235% and GPU power excursions up to 300%, ensuring stable power delivery during peak demands from high-performance components.
6. Mantemento
Un mantemento axeitado garante a lonxevidade e o rendemento óptimo da súa fonte de alimentación.
- Limpeza: Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup. Use compressed air to gently clear dust from the fan blades and internal components. Ensure the PSU is powered off and unplugged before cleaning.
- Xestión de cables Ensure cables are not obstructing airflow within your computer case. Re-route or tie cables as needed to maintain good ventilation.
- Condicións ambientais: Operate the power supply in a clean, dry environment with adequate ventilation. Avoid extreme temperatures and humidity.
