- Connect the 24-pin ATX cable from the power supply to the motherboard.
- Connect the 8-pin (4+4 pin) EPS cable(s) from the power supply to the CPU power connector(s) on the motherboard.
- For graphics cards, connect the appropriate 8-pin (6+2 pin) PCIe cables or the 12V-2x6 cable (for compatible PCIe 5.1 GPUs) from the power supply to the graphics card(s).
- Connect SATA power cables to your storage drives (HDDs, SSDs) and other SATA-powered devices.
- Connect Molex cables to any peripheral devices that require them.
- Ensure all cable connections are secure and properly seated.
- Luk computerens kabinet.
- Tilslut netledningen til strømforsyningen og derefter til en jordet stikkontakt.
6. Betjeningsvejledning
Once installed, operating your FSP VITA GM 850W Power Supply is straightforward.
6.1. Tænd/sluk
- Ensure the power switch on the rear of the power supply is in the 'ON' (I) position.
- Tryk på tænd/sluk-knappen på computerens kabinet for at starte systemet.
- To power off, shut down your operating system normally. For complete power disconnection, switch the power supply to the 'OFF' (O) position and unplug the AC cord.
6.2. Efficiency and Fan Operation
The VITA GM 850W is 80 PLUS Gold certified, meaning it operates with over 90% efficiency at typical loads. This reduces wasted energy, heat generation, and noise. The integrated 120mm HYB fan is designed for quiet and efficient cooling, adjusting its speed based on the power supply's temperature and load to maintain optimal performance and acoustics.

7. Vedligeholdelse
Korrekt vedligeholdelse sikrer strømforsyningens levetid og optimale ydeevne.
- Rensning: Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup. Use a soft, dry cloth or compressed air. Ensure the power supply is unplugged before cleaning.
- Luftstrøm: Ensure that the power supply's intake and exhaust vents are not obstructed. Good airflow is crucial for efficient cooling.
- Kabelstyring: Maintain tidy cable management within your PC case to promote better airflow and prevent cables from interfering with the power supply fan.
8. Fejlfinding
If you encounter issues with your FSP VITA GM 850W Power Supply, refer to the following common problems and solutions.
8.1. Almindelige problemer
- Ingen strøm:
- Kontroller, om netledningen er korrekt tilsluttet både strømforsyningen og stikkontakten.
- Ensure the power switch on the PSU is in the 'ON' (I) position.
- Kontroller, at stikkontakten fungerer ved at tilslutte en anden enhed.
- Check all modular cable connections to the motherboard and components.
- Systemustabilitet/Tilfældige nedlukninger:
- This could indicate an overloaded system or a component issue. Ensure your system's power requirements do not exceed 850W.
- Check for proper ventilation and ensure the power supply fan is spinning. Overheating can trigger protection mechanisms.
- Kontroller, at alle kabelforbindelser er sikre.
- Høj ventilatorstøj:
- Ensure the power supply's fan intake/exhaust is not obstructed.
- Clean any dust buildup on the fan blades or grille.
- High system load will naturally increase fan speed. If noise is excessive at low loads, contact support.
8.2. Beskyttelsesfunktioner
The FSP VITA GM 850W Power Supply includes several protection features to safeguard your system:
- OVP (overvoltage beskyttelse): Shuts down the PSU if output voltages exceed a safe level.
- OCP (overstrømsbeskyttelse): Shuts down the PSU if current on a single rail exceeds a safe level.
- OPP (Overpower Protection): Shuts down the PSU if the total power draw exceeds its maximum wattage.
- UVP (Undervoltage beskyttelse): Shuts down the PSU if output voltages drop below a safe level.
- SCP (Short Circuit Protection): Shuts down the PSU in case of a short circuit on any output rail.
- OTP (Overtemperature Protection): Shuts down the PSU if internal temperatures become too high.
