4. Mainboard Power: Connect the 24-pin ATX cable from the PSU to the corresponding port on your motherboard.
5. CPU Power: Connect the 4+4-pin or 8-pin CPU power cable(s) to the CPU power connector(s) on your motherboard.
6. PCIe Power: For graphics cards, use the appropriate PCIe 6+2-pin or the native 12V-2x6 (12+4-pin) cable for PCIe 5.1 compatible GPUs. Ensure all required power connectors on your graphics card are populated.
7. SATA Power: Connect SATA power cables to SSDs, HDDs, and optical drives.
8. 4P Molex Power: Connect Molex cables for older peripherals or case fans if needed.
9. Once all internal connections are made, manage your cables for optimal airflow and aesthetics.
10. Connect the AC power cord to the PSU's inlet and then to a wall outlet.

6. Operating Instructions

6.1 Initial Power On

1. Ensure the power switch on the back of the PSU is in the 'OFF' (0) position.
2. Connect the AC power cord to the PSU and a wall outlet.
3. Flip the power switch on the PSU to the 'ON' (I) position.
4. Press the power button on your computer case to start the system.

6.2 Semi-Fanless Operation

The ENERMAX Revolution PSU features semi-fanless technology. The cooling fan will remain off when the power load is below approximately 20% to provide silent operation. As the system load increases, the fan will automatically activate and adjust its speed to maintain optimal temperatures. This is normal operation and not an indication of a malfunction.

7. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your power supply.

• Dust Cleaning: Periodically clean the exterior of the power supply and the fan grille to prevent dust buildup, which can impede airflow and cooling. Use compressed air or a soft brush. Always disconnect the PSU from AC power before cleaning.
• Cable Inspection: Occasionally check all modular cable connections to ensure they are secure and free from damage.
• Environment: Ensure the PC operates in a clean, dry, and well-ventilated environment.
