5. Bedienungsanleitung
The Antec GSK850 V2 PSU is designed for efficient and quiet operation.
5.1. Zero RPM Manager
This PSU features a Zero RPM fan mode. In this mode, the 120mm silent fan remains off under low to moderate loads, ensuring silent operation. The thermal sensors activate the fan only when necessary, typically under higher power loads, to maintain optimal cooling and extend the PSU's lifespan.

Figure 5.1: Zero RPM Manager fan curve and 120mm silent fan illustration.
5.2. Ein-/Ausschalten
- To power on your system, ensure the PSU's main power switch is in the "ON" position, then press your computer's power button.
- To power off your system, shut down your operating system normally. For complete power disconnection, flip the PSU's main power switch to the "OFF" position and unplug the AC power cord.
6. Wartung
Proper maintenance can extend the lifespan of your PSU and ensure optimal performance.
- Reinigung: Periodically clean the exterior of the PSU and the fan intake/exhaust vents using compressed air to remove dust buildup. Ensure the PSU is powered off and unplugged before cleaning.
- Kabelmanagement: Regularly check that all modular cables are securely connected and not obstructing airflow within the case.
- Umfeld: Maintain a clean, dry, and well-ventilated environment for your computer system.
7. Fehlerbehebung
If you encounter issues with your Antec GSK850 V2 PSU, refer to the following common troubleshooting steps.
7.1. Kein Strom / System schaltet sich nicht ein
- Stromanschlüsse prüfen: Ensure the AC power cord is securely plugged into both the PSU and the wall outlet. Verify the PSU's main power switch is in the "ON" position.
- Interne Verbindungen: Confirm that the 24-pin motherboard cable, 8-pin CPU cable, and all other necessary modular cables are firmly connected to both the PSU and the respective components.
- Steckdose: Test the wall outlet with another device to ensure it is providing power.
- Power Button/Front Panel: Ensure your case's front panel connectors (especially the power switch) are correctly connected to the motherboard.
7.2. System Instability / Random Shutdowns
- Überlast: Stellen Sie sicher, dass der Strombedarf Ihres Systems die Kapazität des Netzteils von 850 W nicht überschreitet.
- Überhitzung: Check for proper ventilation within your PC case. Ensure the PSU fan is not obstructed and is operating when under load.
- Lose Verbindungen: Re-seat all power cables to ensure they are making proper contact.
- Komponentenprobleme: Instability can also be caused by other components (RAM, GPU, CPU). If the PSU seems fine, test other components.
7.3. Fan Noise
- Zero-RPM-Modus: The fan may not spin under low loads. This is normal operation for the Zero RPM Manager.
- Staubansammlung: Reinigen Sie den Ventilator und die Lüftungsschlitze wie im Abschnitt Wartung beschrieben.
- Obstruktion: Ensure no cables or foreign objects are interfering with the fan blades.
If these steps do not resolve your issue, please contact Antec customer support.
