5. Setup

Follow these steps to properly install your XPG Core Reactor II 850W Power Supply:

1. Prepare Your System: Ensure your computer is powered off and unplugged from the wall. Open your PC case to access the power supply mounting area.
2. Mount the PSU: Secure the XPG Core Reactor II PSU into the designated power supply bay in your PC case using the provided mounting screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards or towards an intake vent).
3. Connect Essential Cables:
   • 24-Pin ATX Motherboard Cable: Connect the large 24-pin cable from the PSU to the corresponding port on your motherboard.
   • CPU Power Cables: Connect the 4+4-pin or 8-pin CPU power cables to the CPU power headers on your motherboard. Modern motherboards may require two such connections.
   • GPU Power Cables: For graphics cards requiring a 12VHPWR connector, use the dedicated 12VHPWR (12+4) cable. For other GPUs, use the appropriate 6+2-pin PCI-E cables. Ensure all connections are fully seated.
   • SATA/Molex Cables: Connect SATA power cables to your storage drives (SSDs, HDDs) and Molex cables to any other peripherals requiring them.
4. Cable Management: Utilize the fully modular design to connect only the necessary cables, improving airflow and aesthetics within your case. Route cables neatly to prevent obstruction.
5. Final Check: Double-check all connections to ensure they are secure. Close your PC case.

6. Operating Instructions

After successful installation, connect the AC power cord to the PSU and then to a wall outlet. Flip the main power switch on the back of the PSU to the 'ON' position. You can then power on your computer as usual.

The XPG Core Reactor II features an intelligent FDB fan control. The fan operates silently at low loads and adjusts its speed dynamically to maintain optimal temperatures under heavier loads. This ensures efficient cooling without unnecessary noise.

7. Maintenance

To ensure the longevity and optimal performance of your power supply, consider the following maintenance tips:

• Keep it Clean: Periodically clean the exterior of the power supply and its fan grill to prevent dust buildup, which can impede airflow and cooling efficiency. Use compressed air for hard-to-reach areas.
• Ensure Proper Ventilation: Make sure your PC case has adequate airflow and that the power supply's intake and exhaust vents are not obstructed.
• Avoid Overloading: Ensure your system's power consumption does not consistently exceed the PSU's rated wattage.

8. Troubleshooting

If you encounter issues with your XPG Core Reactor II 850W Power Supply, try the following steps:

• No Power:
  • Check if the AC power cord is securely connected to both the PSU and the wall outlet.
  • Ensure the main power switch on the PSU is in the 'ON' position.
  • Verify that the 24-pin ATX and CPU power cables are correctly and firmly connected to the motherboard.
• System Instability/Random Shutdowns:
  • Ensure all component power cables (GPU, CPU, etc.) are securely connected.
  • Confirm that your system's total power draw does not exceed the 850W capacity of the PSU. High-end components, especially GPUs, can have significant power spikes.
  • Check for proper ventilation within your PC case to prevent overheating.
• Unusual Noise:
  • If the fan is unusually loud, ensure it is not obstructed by cables or dust.
  • A slight buzzing noise under heavy load can sometimes occur with certain components; however, persistent loud or grinding noises may indicate a fan issue.

If issues persist after following these steps, please contact XPG customer support.
