4. Setup and Installation

Follow these steps to install your Rosewill CMG5 1000W Power Supply:

1. Prepare Your System:
   • Turn off your computer and disconnect the AC power cord from the wall outlet.
   • Open your computer case.
   • If replacing an existing power supply, disconnect all cables from the old PSU and remove it from the case.
2. Install the Power Supply:
   • 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).
3. Connect Modular Cables:
   • 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.
4. Final Checks:
   • 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.
   • Close your computer case.
5. Power On:
   • Connect the AC power cord to the power supply and then to a wall outlet.
   • Flip the main power switch on the back of the PSU to the "ON" position.
   • Power on your computer.

5. Operating Instructions

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 OFF, 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. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply.

• Cleaning: 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.
• Cable Management: Ensure cables are not obstructing airflow within your computer case. Re-route or tie cables as needed to maintain good ventilation.
• Environmental Conditions: Operate the power supply in a clean, dry environment with adequate ventilation. Avoid extreme temperatures and humidity.
