5. Installation and Setup
Follow these steps to properly install your power supply:
- Mounting the Power Supply: Secure the power supply unit into the designated PSU bay of your PC case using the provided screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards or towards the interior of the case, depending on case design).
- Connecting Main Power (Motherboard): Connect the 20/24-pin Main Power connector to your motherboard.
- Important: The 24-pin motherboard connector can be split into a 20+4 connector for motherboards requiring a 20-pin power connector.
- Connecting CPU Power: Connect the 4+4-pin 12V CPU power connector to your motherboard.
- Important: The 8-pin CPU connector can be split into a 4+4 connector for motherboards that require a 4-pin power connector.
- Connecting PCI-E Power (Graphics Card): Attach the 6+2-pin PCI-E connectors to your graphics card(s). This power supply includes 2 x PCI 6+2pin connectors.
- Important: The 8-pin PCI-E GPU connector can be split into a 6+2 connector for graphics cards that require a 6-pin power connector.
- Connecting SATA and Peripheral Devices: Use the modular cables to connect your SATA drives (HDDs, SSDs) and other peripheral devices (fans, optical drives) that require peripheral (Molex) power. This power supply includes 4 x SATA and 4 x Peripheral connectors.
- Cable Management: Route all cables neatly to ensure proper airflow within your PC case.
- AC Voltage Selection: Ensure the 115/230V switch on the back of the power supply is set to the correct voltage for your region. Incorrect voltage selection can damage the unit.
- Final Power Connection: Connect the AC power cord to the power supply and then to a wall outlet.
- Important: The power supply will not power on simply by connecting the power cord to both the power supply and wall outlet. Ensure that all the power supply cables are properly connected to the PC for it to power on.
