5. Setup and Installation
Follow these steps to install your PCCOOLER CPS YS850 power supply:
- Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your computer case.
- Remove Old PSU (if applicable): Disconnect all cables from your old power supply. Unscrew and remove the old PSU from the case.
- Mount the New PSU: Carefully slide the PCCOOLER CPS YS850 into the power supply bay of your computer case. Secure it with the provided mounting screws. Ensure the fan is facing the correct direction for optimal airflow (typically facing downwards if your case has a bottom vent, or upwards if it's a top-mounted PSU).
- Connect Modular Cables: Identify the necessary cables for your motherboard, CPU, graphics card(s), and storage devices. Connect these cables to the corresponding ports on the power supply first. Refer to the cable overview in Section 3.
- Connect to Components: Route the connected modular cables through your case's cable management channels. Connect the 24-pin motherboard cable, 4+4-pin CPU cable(s), 6+2-pin PCIe cables (for graphics cards), 12V-2x6 cable (for compatible GPUs), and SATA/peripheral cables to your components.
- Cable Management: Use the included cable ties or combs to organize cables for better airflow and a cleaner build.
- Connect AC Power: Once all internal connections are secure, close your computer case. Connect the AC power cord to the power supply and then to a grounded wall outlet.
- Power On: Flip the power switch on the back of the power supply to the 'ON' (I) position. Power on your computer.

6. Operating Instructions
Fan Operation Modes:
The PCCOOLER CPS YS850 features a selectable fan mode for optimized cooling and noise levels.
Image: A close-up of the fan mode switch on the PCCOOLER YS850 power supply, indicating the 'Hybrid Mode' (unpressed) and 'Standard Mode' (pressed down) options.
- Hybrid Mode (Button Unpressed): In this mode, the fan remains off when the power supply load is below 30% and the internal temperature is low. This provides silent operation during light workloads. The fan will automatically activate and adjust its speed as the load or temperature increases.
- Standard Mode (Button Pressed Down): In this mode, the fan operates continuously, with its speed automatically adjusting based on the internal temperature and power supply workload. This ensures consistent cooling performance.
Select the desired mode using the switch located on the power supply unit.
7. Maintenance
Proper maintenance helps ensure the longevity and optimal performance of your power supply:
- Keep Clean: Regularly clean dust from the power supply's fan and ventilation grilles using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Ensure Airflow: Verify that nothing is obstructing the intake or exhaust vents of the power supply. Good airflow is crucial for cooling.
- Cable Integrity: Periodically check modular cables for any signs of damage or loose connections.
- Environmental Conditions: Operate the power supply in a cool, dry, and well-ventilated environment.
8. Troubleshooting
If you encounter issues with your power supply, refer to the following common troubleshooting steps:
- No Power:
- Ensure the AC power cord is securely connected to both the power supply and the wall outlet.
- Check that the power switch on the back of the PSU is in the 'ON' (I) position.
- Verify that all modular cables (24-pin, CPU, PCIe) are firmly seated in both the PSU and the respective components.
- Test the wall outlet with another device to confirm it has power.
- System Instability/Crashes:
- Ensure your system's power requirements do not exceed the PSU's 850W capacity.
- Check for loose cable connections.
- Monitor system temperatures to ensure components are not overheating.
- Fan Not Spinning (in Hybrid Mode):
- This is normal behavior in Hybrid Mode if the load is below 30% and temperatures are low. The fan will spin up when needed.
- If the fan does not spin even under heavy load, switch to Standard Mode to see if it operates. If not, contact support.
- Unusual Noises:
- Ensure no cables are interfering with the fan blades.
- If you hear persistent coil whine or other abnormal sounds, power down the system immediately and contact customer support.
If these steps do not resolve your issue, please refer to the Warranty and Support section for further assistance.
