5. Nastavení a instalace
Follow these steps to install your Antec GSK850 PSU into your computer system:
- Připravte si systém: Ujistěte se, že je počítač zcela vypnutý a odpojený od zásuvky. Otevřete kryt počítače.
- Demontáž starého zdroje (pokud je k dispozici): If replacing an existing PSU, disconnect all cables from the old PSU and remove its mounting screws. Carefully slide it out of the case.
- Montáž nového zdroje: 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.
- Připojení základních kabelů: 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:
- 24pinový kabel základní desky ATX: Connect to your motherboard's main power connector.
- 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.
- Napájecí kabely SATA: Connect to SSDs, HDDs, and optical drives.
- Kabely Molex: Connect to any peripherals requiring Molex power.
- Správa kabelů: Kabely veďte úhledně za přihrádkou základní desky nebo do vyhrazených prostor pro správu kabelů, abyste zlepšili proudění vzduchu a estetiku.
- Zavřete skříň a připojte napájení: 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. Návod k obsluze
Operating the Antec GSK850 PSU is straightforward:
- Zapnutí: 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.
- Režim nulových otáček: 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.
- Vypnout: 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. Údržba
Správná údržba zajišťuje dlouhou životnost a optimální výkon vašeho zdroje:
- Odstranění prachu: 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.
- Kontrola kabelů: Occasionally inspect all connected cables for any signs of wear, damage, or loose connections.
- Prostředí: Ensure the PSU operates in a clean, dry, and well-ventilated environment.
8. Řešení problémů
If you encounter issues with your Antec GSK850 PSU, refer to the following common troubleshooting steps:
- Bez napájení:
- Ujistěte se, že je napájecí kabel bezpečně zapojený do zdroje napájení i do zásuvky.
- 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.
- Otestujte zásuvku ve zdi pomocí jiného zařízení, abyste se ujistili, že je pod proudem.
- Nestabilita/pády systému:
- Ensure your PSU wattage je dostatečné pro všechny komponenty vašeho systému.
- Zkontrolujte, zda nejsou uvolněné kabelové spoje.
- 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.

- Ventilátor se netočí:
- 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.
