Setup
Follow these steps to install your power supply:
- Mounting the PSU: Secure the power supply unit into the designated bay in your computer case using the provided mounting 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: Connect the 20/24-pin Main Power connector to your motherboard. Note that the 24-pin motherboard connector can be split into a 20+4 connector for motherboards requiring a 20-pin power connection.
- Connecting CPU Power: Connect the 8-pin ESP 12V connector to your motherboard's CPU power socket. 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 Devices: Use the 8(6+2)-pin PCI-E connectors for your graphics cards. 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 Devices: Connect the SATA power cables to your storage drives (SSDs, HDDs) and optical drives.
- Connecting Peripheral Devices: Use the Peripheral (Molex) connectors for older components or case fans that require this type of power. A Floppy connector is also available for legacy devices.
- Cable Management: Utilize the semi-modular design to connect only the necessary cables, improving airflow and aesthetics within your PC case. Store unused modular cables for future use.
- Final Power Connection: Once all internal components are connected, plug the AC power cord into the power supply and then into 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.

Thermal Control
The 135mm RGB fan is auto-thermally controlled. This means the fan speed will automatically adjust based on the power supply's internal temperature, spinning faster when hotter and slower when cooler, ensuring optimal cooling and reduced noise levels.
Maintenance
To ensure the longevity and optimal performance of your Apevia power supply, consider the following maintenance tips:
- Dust Removal: Periodically clean dust from the power supply's fan and vents using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Airflow: Ensure that the power supply's intake and exhaust vents are not obstructed. Good airflow within your PC case is crucial for efficient cooling.
- Cable Management: While the semi-modular design aids in cable management, periodically check that cables are not obstructing airflow or pressing against components.
Troubleshooting
If you encounter issues with your power supply, refer to the following common troubleshooting steps:
- Power Supply Not Turning On:
- Ensure the AC power cord is securely plugged into both the power supply and the wall outlet.
- Verify that the power switch on the back of the PSU is in the 'ON' position.
- Crucially, confirm that all power supply cables (20/24-pin Main, CPU, PCI-E, SATA, etc.) are properly and securely connected to their respective components within the PC. The PSU requires a load to power on.
- Test the wall outlet with another device to ensure it is supplying power.
- System Instability/Random Shutdowns:
- Check all cable connections for looseness.
- Ensure adequate ventilation around the power supply and within the PC case to prevent overheating.
- Verify that your system's power requirements do not exceed the 650W capacity of the PSU.
- RGB Fan Not Lighting Up:
- Press the RGB mode button on the back of the PSU to cycle through modes or turn it on.
- Ensure the PSU is receiving power and the system is running.
