4.2 Cable Connections

The GSK750 V2 is a full modular PSU, meaning you only connect the cables you need, which helps improve airflow and cable management within your case.

1. Connect the necessary modular cables to the power supply unit. Refer to the labels on the PSU and the cables to ensure correct connections.
2. Connect the 24-pin ATX cable to your motherboard.
3. Connect the 8-pin (4+4) EPS/CPU cables to your motherboard's CPU power connectors.
4. For graphics cards, use the appropriate PCIe cables. The GSK750 V2 supports PCIe 5.1 with a dedicated 12V-2x6 (450W) cable for modern GPUs. Connect these securely to your graphics card(s).
5. Connect SATA power cables to your storage drives (SSDs, HDDs) and other SATA-powered devices.
6. Connect Molex cables for any peripherals that require them.

4.3 Initial Power Up

1. Once all internal connections are made, close your computer case.
2. Connect the AC power cord to the PSU and then to a wall outlet.
3. Flip the power switch on the back of the PSU to the 'ON' position.
4. Power on your computer.

5. Operating Instructions

The Antec GSK750 V2 PSU is designed for reliable and efficient operation with minimal user intervention.

5.1 Zero RPM Manager

This power supply features a Zero RPM Manager mode. In this mode, the 120mm silent fan remains off under low to moderate loads to provide silent operation. The fan will automatically activate when the power load increases, ensuring optimal cooling while minimizing noise levels.

6. Maintenance

To ensure the longevity and optimal performance of your Antec GSK750 V2 power supply, follow these simple maintenance guidelines:

• Keep Vents Clear: Ensure that the intake and exhaust vents of the power supply are not obstructed by dust or other objects. Proper airflow is crucial for cooling.
• Regular Cleaning: Periodically clean the exterior of the power supply and its fan grille using compressed air to remove dust buildup. Always disconnect the PSU from the AC power before cleaning.
• Cable Management: Maintain tidy cable management within your PC case to prevent cables from obstructing airflow to the PSU and other components.

7. Troubleshooting

If you encounter issues with your Antec GSK750 V2 power supply, refer to the following common problems and solutions:

7.1 No Power to System

• Check AC Power: Ensure the AC power cord is securely connected to both the PSU and the wall outlet. Verify the wall outlet is functional.
• PSU Switch: Confirm the power switch on the back of the PSU is in the 'ON' position.
• Internal Connections: Double-check all modular cable connections to the PSU and to your components (motherboard, CPU, GPU). Ensure the 24-pin and 8-pin CPU cables are fully seated.
• Motherboard Stand-offs: Ensure your motherboard is properly installed with stand-offs to prevent short circuits.

7.2 System Instability or Random Shutdowns

• Overload: Ensure your system's power requirements do not exceed the 750W capacity of the PSU.
• Overheating: Check for proper airflow within your case and ensure the PSU fan is operating when under load. Clean any dust buildup.
• CircuitShield Protection: The Antec GSK750 V2 includes comprehensive industrial-grade protections (OCP, OVP, UVP, SCP, OPP, OTP, SIP, NLO). If the PSU detects an unsafe condition, it may shut down to protect your components. If this occurs repeatedly, consult a professional.

7.3 Fan Not Spinning

• Zero RPM Mode: Under low loads, the fan will not spin. This is normal operation. The fan will activate automatically as the system load increases.
• Obstruction: Ensure nothing is physically blocking the fan blades.

If problems persist after following these steps, please contact Antec customer support.
