5. Einrichtung und Installation
Follow these steps to install your Antec GSK850 PSU into your computer system:
- Bereiten Sie Ihr System vor: Stellen Sie sicher, dass Ihr Computer vollständig ausgeschaltet und vom Stromnetz getrennt ist. Öffnen Sie das Computergehäuse.
- Altes Netzteil entfernen (falls zutreffend): If replacing an existing PSU, disconnect all cables from the old PSU and remove its mounting screws. Carefully slide it out of the case.
- Das neue Netzteil einbauen: Slide the Antec GSK850 into the PSU mounting bay of your computer case. Align the screw holes and secure the PSU with the provided mounting screws.
- Wichtige Kabel anschließen: Refer to Figure 4.2 for cable types and lengths. Connect the necessary modular cables to the PSU first, then to your motherboard and components:
- 24-poliges ATX-Motherboard-Kabel: Schließen Sie es an den Hauptstromanschluss Ihres Motherboards an.
- 8-pin (4+4) CPU Power Cable(s): Connect to your motherboard's CPU power connector(s).
- PCIe 5.1 12VHPWR (16-pin) or 8-pin (6+2) PCIe Cables: Connect to your graphics card(s) as required.
- SATA-Stromkabel: Anschlussmöglichkeiten für SSDs, HDDs und optische Laufwerke.
- Molex-Kabel: Connect to any peripherals requiring Molex power.
- Kabelmanagement: Route cables neatly behind the motherboard tray or in designated cable management areas to improve airflow and aesthetics.
- Gehäuse schließen und Strom anschließen: Once all connections are secure, close your computer case. Plug the AC power cord into the PSU and then into a grounded wall outlet.
6. Bedienungsanleitung
Operating the Antec GSK850 PSU is straightforward:
- Einschalten: After installation, ensure the power switch on the back of the PSU is in the 'ON' (I) position. Then, power on your computer using the case's power button.
- Zero-RPM-Modus: The PSU's fan will remain off when the power load is low, providing silent operation. As the system load increases, the fan will automatically activate and adjust its speed to maintain optimal temperatures. This is normal operation and indicates the Zero RPM Manager is functioning correctly.
- Ausschalten: To power off your system, use the operating system's shutdown function. For complete power disconnection, switch the PSU's power switch to the 'OFF' (O) position and unplug the AC power cord from the wall outlet.
7. Wartung
Proper maintenance ensures the longevity and optimal performance of your PSU:
- Staubentfernung: Periodically clean dust from the PSU's fan grille and ventilation openings using compressed air. Ensure the PSU is powered off and unplugged before cleaning.
- Kabelinspektion: Occasionally inspect all connected cables for any signs of wear, damage, or loose connections.
- Umfeld: Ensure the PSU operates in a clean, dry, and well-ventilated environment.
8. Fehlerbehebung
If you encounter issues with your Antec GSK850 PSU, refer to the following common troubleshooting steps:
- Kein Strom:
- Ensure the AC power cord is securely plugged into both the PSU and the wall outlet.
- Check that the PSU's power switch on the back is in the 'ON' (I) position.
- Verify all modular cables are securely connected to both the PSU and the components.
- Prüfen Sie die Steckdose mit einem anderen Gerät, um sicherzustellen, dass sie Strom liefert.
- Systeminstabilität/Abstürze:
- Stellen Sie sicher, dass Ihr Netzteiltage is sufficient for all your system components.
- Auf lockere Kabelverbindungen prüfen.
- The PSU's CircuitShield protection suite (OCP, OVP, UVP, SCP, OPP, OTP, SIP, NLO) will automatically shut down the PSU in case of an electrical fault to protect your components. If this occurs, disconnect power, check for short circuits or faulty components, and then attempt to restart.

- Lüfter dreht sich nicht:
- The GSK850 features Zero RPM mode. The fan will not spin at low loads. This is normal. The fan will activate when the system load increases.
- If the fan does not spin even under high load, ensure there are no obstructions and contact support if the issue persists.
If the problem persists after following these steps, please contact Antec customer support.
