Installation Steps
- Prepare Your System: Ensure your computer is powered off and unplugged from the wall. Open your PC case.
- Mount the PSU: Secure the PCCOOLER YN850 power supply into the designated PSU bay in your PC case using the provided mounting screws.
- Connect Main Power: Connect the 24-pin M/B cable to your motherboard.
- Connect CPU Power: Connect the 4+4-pin CPU cable(s) to your motherboard's CPU power connector(s).
- Connect GPU Power: For graphics cards requiring PCIe 5.1, use the 12V-2x6 cable. For other graphics cards, use the 6+2-pin PCI-E cables. Connect these to your graphics card(s).
- Connect Peripherals: Connect SATA and peripheral cables to your storage drives (SSDs, HDDs) and other devices as needed.
- Cable Management: Use the provided zip ties to neatly route and secure all cables, ensuring optimal airflow and a clean build.
- Close Case and Power On: Close your PC case, connect the AC power cord to the PSU and a wall outlet, then power on your system.
Operation
Powering On/Off
The power supply features a main ON/OFF switch located at the rear. Ensure this switch is in the 'ON' position for the system to receive power. Always turn off this switch and unplug the AC cord before performing any internal maintenance or component changes.
80 Plus Gold Efficiency
The PCCOOLER YN850 is 80 Plus Gold certified, meaning it achieves over 91% power conversion efficiency under typical load conditions. This results in reduced energy consumption, lower heat generation, and decreased operating costs.

135mm FDB Fan with Zero RPM Mode
The power supply incorporates a 135mm Fluid Dynamic Bearing (FDB) fan for efficient cooling and quiet operation. The FDB design reduces wear, ensuring long-term stability and low noise levels.
It supports a Zero RPM Fan Mode, where the fan remains off under low temperature and light load conditions, providing silent operation. The fan will automatically activate as the load and temperature increase to maintain optimal cooling.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your power supply.
- Cleaning: Periodically clean the exterior of the power supply and its fan grille using a soft, dry cloth. For deeper cleaning, use compressed air to remove dust from the fan and internal components, ensuring the system is powered off and unplugged.
- Ventilation: Ensure that the air intake and exhaust vents of the power supply are not obstructed. Maintain adequate airflow within your PC case.
- Cable Management: Regularly check cable connections to ensure they are secure and not interfering with airflow.
- Environment: Operate the power supply in a stable environment, avoiding extreme temperatures, high humidity, and direct sunlight.
Troubleshooting
If you encounter issues with your PCCOOLER CPS YN850 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.
- Verify the ON/OFF switch on the PSU is in the 'ON' position.
- Check if the wall outlet is functional by plugging in another device.
- Confirm all modular cables are correctly and firmly seated in both the PSU and the respective components (motherboard, GPU, etc.).
- System Instability/Crashes:
- Ensure your system's total power draw does not exceed the PSU's 850W capacity.
- Check for loose cable connections.
- Monitor system temperatures to ensure components are not overheating.
- If using a new graphics card, ensure it is properly connected with the correct PCIe power cables (e.g., 12V-2x6 for PCIe 5.1).
- Fan Not Spinning (Zero RPM Mode):
- The fan may not spin under low load or low temperature conditions due to the Zero RPM Fan Mode. This is normal operation.
- If the fan does not spin under heavy load or high temperatures, ensure the ECO mode switch (if present and enabled) is functioning correctly, or disable it to force the fan to spin.
- Unusual Noises:
- Ensure no cables are obstructing the fan blades.
- If a persistent grinding or buzzing noise occurs, contact customer support.
If the problem persists after following these steps, please refer to the Warranty & Support section for further assistance.
