4.3 Powering On
After all connections are secure, connect the AC power cord to the power supply and a wall outlet. Flip the power switch on the PSU to the 'ON' position. You can then power on your computer system.
5. Operation
5.1 Zero RPM Fan Mode
The SAMA P1000 features a Zero RPM fan mode. The 140mm FDB fan remains off when the power supply load is below 60% or the internal temperature is below 55°C, ensuring silent operation during light tasks. The fan will automatically activate and adjust its speed based on load and temperature to maintain optimal cooling.

8. Troubleshooting
If you encounter issues with your SAMA P1000 power supply, 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 PSU is in the 'ON' position.
- Verify all modular cables are firmly seated in both the PSU and the respective components (motherboard, GPU, etc.).
- Test the wall outlet with another device to confirm it has power.
- System Instability/Crashes:
- Ensure your system's total power draw does not exceed the PSU's 1000W capacity.
- Check for loose cable connections.
- Monitor system temperatures to ensure components are not overheating.
- Fan Not Spinning:
- The SAMA P1000 features a Zero RPM fan mode. The fan will not spin under low loads (below 60%) or low internal temperatures (below 55°C). This is normal operation.
- If the system is under heavy load and the fan is still not spinning, ensure there are no obstructions to the fan.
9. 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 grille and vents using compressed air. Ensure the PSU is powered off and unplugged before cleaning.
- Ensure Airflow: Maintain good airflow within your PC case to prevent heat buildup around the power supply.
- Avoid Obstructions: Do not block the intake or exhaust vents of the power supply.
