- CPU Power: Connect the 8-pin (4+4-pin) CPU cable(s) to the PSU and then to your motherboard's CPU power connector(s).
- PCIe Power: Connect the 6+2-pin PCIe cable(s) to the PSU and then to your graphics card(s). Use separate cables for each high-power GPU connector if possible.
- SATA Power: Connect SATA power cables to the PSU and then to your SSDs, HDDs, or optical drives.
- Peripheral (Molex) Power: Connect peripheral cables to the PSU and then to any components requiring Molex connectors.
- Once all necessary cables are connected, use cable ties to manage them neatly for better airflow and aesthetics.
5.4 Initial Power-On
- Ensure all connections are secure.
- Close your computer case.

6. Operating Instructions
6.1 Powering On/Off
To power on your system, ensure the PSU switch is in the 'ON' position and press your computer's power button. To power off, shut down your operating system normally. For complete power disconnection, flip the PSU switch to the 'OFF' (O) position and unplug the AC cord.
6.2 Zero RPM Mode
The Montech Titan PLA 850W features a Zero RPM mode. In this mode, the PSU fan will remain off under low to moderate loads to provide silent operation. The fan will automatically activate when the load increases to maintain optimal temperatures. This is normal operation and not an indication of a fault.

7. Maintenance
To ensure the longevity and optimal performance of your Montech Titan PLA 850W PSU, follow these maintenance guidelines:
- Dust Removal: Periodically clean the exterior of the PSU and the fan grill to prevent dust buildup. Use compressed air to gently clear dust from the fan blades and internal components. Always disconnect the AC power before cleaning.
- Environmental Conditions: Operate the PSU in a well-ventilated area, away from direct sunlight, heat sources, and excessive humidity.
- Cable Inspection: Occasionally check all modular cable connections to ensure they are secure and free from damage.
8. Troubleshooting
If you encounter issues with your Montech Titan PLA 850W PSU, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on. | AC power cord disconnected. PSU switch is OFF. Loose cable connections. Faulty component. | Ensure AC cord is securely plugged in. Flip PSU switch to 'ON' (I). Check all modular cable connections. Test PSU with a PSU tester (if available) or try minimal components. |
| System powers on but is unstable/shuts down. | Overload. Overheating. Faulty component. | Ensure total system wattage does not exceed 850W. Check for proper case ventilation and dust buildup. Verify all components are correctly installed. |
| PSU fan is not spinning. | Zero RPM mode active. Fan obstruction. Faulty fan. | This is normal under low loads. The fan will spin up when needed. Check for any obstructions. Clean dust if necessary. If fan never spins under load, contact support. |
