5. Operating Instructions

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.

5.2. Power On/Off

• 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. Maintenance

Proper maintenance can extend the lifespan of your PSU and ensure optimal performance.

• Cleaning: 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.
• Cable Management: Regularly check that all modular cables are securely connected and not obstructing airflow within the case.
• Environment: Maintain a clean, dry, and well-ventilated environment for your computer system.

7. Troubleshooting

If you encounter issues with your Antec GSK850 V2 PSU, refer to the following common troubleshooting steps.

7.1. No Power / System Not Turning On

• Check Power Connections: 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.
• Internal Connections: 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.
• Wall Outlet: 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

• Overload: Ensure your system's power requirements do not exceed the PSU's 850W capacity.
• Overheating: Check for proper ventilation within your PC case. Ensure the PSU fan is not obstructed and is operating when under load.
• Loose Connections: Re-seat all power cables to ensure they are making proper contact.
• Component Issues: 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 Mode: The fan may not spin under low loads. This is normal operation for the Zero RPM Manager.
• Dust Buildup: Clean the fan and vents as described in the Maintenance section.
• Obstruction: 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.
