5. Installation

Follow these steps to install your COUGAR GEX850 PSU into your computer system:

1. Prepare Your System: Ensure your computer is powered off and the power cord is disconnected from the wall outlet. Open your computer case.
2. Remove Old PSU (if applicable): Disconnect all cables from your old power supply and remove it from the case.
3. Mount the PSU: Insert the COUGAR GEX850 into the PSU mounting bay of your computer case. Secure it with the provided 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).
4. Connect Essential Cables:
   • 24-pin ATX Motherboard Cable: Connect the large 24-pin cable to the corresponding port on your motherboard.
   • CPU 4+4-pin Cable: Connect the 4+4-pin CPU power cable to the CPU power connector on your motherboard (usually near the CPU socket).
   • PCIe 6+2-pin Cables: Connect the 6+2-pin PCIe cables to your graphics card(s) as required.
5. Connect Peripheral Cables: Connect SATA power cables to your storage drives (HDDs, SSDs) and optical drives. Connect Peripheral 4-pin cables to any other components requiring this type of power.
6. Cable Management: Utilize the fully modular design and flat cables to route cables neatly behind the motherboard tray or in other designated areas to improve airflow and aesthetics.
7. Close Case and Connect Power: Once all connections are secure, close your computer case. Connect the AC power cord to the PSU and then to a wall outlet.

6. Operation

After successful installation, you can power on your computer system. The COUGAR GEX850 PSU will provide stable and efficient power to all connected components.

• Power On: Press the power button on your computer case. The PSU fan will begin to spin, and your system should boot normally.
• Efficiency: The 80 Plus Gold certification ensures high power conversion efficiency, which translates to less wasted energy and lower operating temperatures.
• Cooling: The integrated 120mm HDB fan operates quietly and adjusts its speed based on the PSU's temperature and load, maintaining optimal operating conditions.

7. Maintenance

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

• Dust Removal: Periodically clean dust from the PSU's fan grille and interior of your computer case. Use compressed air to gently blow out dust. Ensure the system is powered off and unplugged before cleaning.
• Ventilation: Ensure that the PSU's intake and exhaust vents are not obstructed. Maintain adequate airflow around your computer case.
• Cable Inspection: Occasionally check that all modular cables are securely connected to both the PSU and your components.

8. Troubleshooting

If you encounter issues with your COUGAR GEX850 PSU, refer to the following common troubleshooting steps:

• No Power:
  • Ensure the AC power cord is securely connected to both the PSU and the wall outlet.
  • Check that the power switch on the back of the PSU is in the 'ON' position.
  • Verify all modular cables (24-pin ATX, CPU, PCIe) are firmly seated in both the PSU and the respective components.
  • Test the wall outlet with another device to ensure it is supplying power.
• System Instability/Random Shutdowns:
  • Ensure the PSU is adequately ventilated and not overheating.
  • Check for loose cable connections.
  • The PSU's built-in safeguards (OCP, OPP, OVP, UVP, SCP, OTP) may be activating due to an issue. If this occurs frequently, it could indicate a component drawing too much power or a fault within the system. Consult a qualified technician.
• Fan Not Spinning:
  • Some PSUs feature a 'zero RPM' mode at low loads for silent operation. The fan may not spin until the PSU reaches a certain temperature or load threshold.
  • If the fan never spins even under load, and the system is unstable, contact support.

If these steps do not resolve your issue, please contact COUGAR customer support or your retailer for further assistance.
