4. Configurazione e installazione
Follow these steps to install your Rosewill CMG5 1000W Power Supply:
- Prepara il tuo sistema:
- Spegnere il computer e scollegare il cavo di alimentazione CA dalla presa a muro.
- Apri il case del computer.
- Se si sostituisce un alimentatore esistente, scollegare tutti i cavi dal vecchio alimentatore e rimuoverlo dal case.
- Installare l'alimentatore:
- Carefully place the new Rosewill CMG5 1000W PSU into the power supply bay of your computer case.
- Secure the PSU to the case using the provided mounting screws. Ensure the fan is facing the correct direction for optimal airflow (typically facing down if there's a bottom vent, or up if not).
- Collegare i cavi modulari:
- Identify the necessary cables for your components (Motherboard, CPU, PCIe, SATA, Molex). Refer to the "Package Contents" section for cable types.
- Connect the required modular cables to the corresponding ports on the power supply unit. Ensure they click firmly into place.
- Connect the other end of each cable to your motherboard, CPU, graphics card(s), storage drives, and other peripherals. Pay close attention to the orientation of each connector.
- For PCIe 5.0 graphics cards, use the dedicated 12+4-pin PCIe 5.0 cable. Ensure it is fully inserted into both the PSU and the graphics card.
- Controlli finali:
- Double-check all cable connections to ensure they are secure. Loose connections can cause system instability or damage.
- Organize cables to improve airflow within the case.
- Chiudi il case del computer.
- Accensione:
- Collegare il cavo di alimentazione CA all'alimentatore e quindi a una presa a muro.
- Flip the main power switch on the back of the PSU to the "ON" position.
- Accendi il computer.

5. Istruzioni per l'uso
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 SPENTO, 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. Manutenzione
Una corretta manutenzione garantisce la longevità e le prestazioni ottimali del tuo alimentatore.
- Pulizia: 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.
- Gestione dei cavi: Ensure cables are not obstructing airflow within your computer case. Re-route or tie cables as needed to maintain good ventilation.
- Condizioni ambientali: Utilizzare l'alimentatore in un ambiente pulito e asciutto, con adeguata ventilazione. Evitare temperature e umidità estreme.
