1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Segotep GN-650 650W 80 Plus Gold Certified Non-Modular ATX Power Supply. Please read this manual thoroughly before use and retain it for future reference.
2. General Safety Information
- Electrical Safety: Always disconnect the power supply from the AC outlet before installing, removing, or servicing any components. Ensure your system is properly grounded.
- Ventilation: Ensure adequate airflow around the power supply. Do not block the fan or any ventilation openings.
- Moisture and Temperature: Avoid exposing the power supply to moisture, high humidity, or extreme temperatures. Operate within specified environmental conditions.
- Professional Installation: If you are unsure about any installation steps, consult a qualified technician.
- Internal Components: Do not open the power supply casing. High voltages are present inside, and there are no user-serviceable parts. Opening the unit will void the warranty.
3. Product Features
- 80 Plus Gold Certified: Ensures high power efficiency, reducing energy consumption and heat generation.
- Non-Modular Design: All cables are permanently attached to the power supply, simplifying installation for some users and ensuring all necessary cables are present.
- Single +12V Output: Provides stable and reliable power delivery for demanding components.
- 120mm Silent Fan: Equipped with a quiet fan for effective cooling and reduced noise levels.
- Comprehensive Protection: Includes Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP), Over Power Protection (OPP), and Over Temperature Protection (OTP) for system safety.
- Global Voltage Adaptation: Supports a wide range of AC input voltages (100-240Vac).
4. Setup: Installation Guide
Proper installation is crucial for the performance and longevity of your power supply. Follow these steps carefully.
4.1 Unpacking and Inspection
Carefully remove the power supply from its packaging. Inspect for any signs of damage. If damaged, do not proceed with installation and contact your retailer.

4.2 Mounting the Power Supply
- Ensure your computer case is compatible with ATX form factor power supplies. Refer to the dimensions in the specifications section.
- Position the power supply in the designated PSU bay of your computer case. Ensure the fan is facing the correct direction for optimal airflow (typically facing downwards if your case has a bottom vent, or upwards if not).
- Secure the power supply to the case using the provided screws.

4.3 Cable Connections
The GN-650 features a non-modular design, meaning all cables are pre-attached. Connect the necessary cables to your components.
Figure 3: Available Connectors and Lengths
- 24-Pin ATX Mainboard Connector: Connect to the main power socket on your motherboard.
- 4+4-Pin CPU Power Connector: Connect to the CPU power socket on your motherboard. This may be an 8-pin or 4-pin connector depending on your motherboard.
- 6+2-Pin PCI-E Connectors (x4): Connect to your graphics card(s). These connectors are designed to be flexible for 6-pin or 8-pin GPU power inputs.
- SATA Connectors (x6): Connect to SATA devices such as SSDs, HDDs, and optical drives.
- Molex Peripheral Connectors (x3): Connect to older peripherals or case fans.
- FDD Connector (x1): For legacy floppy disk drives, if applicable.

5. Operating Instructions
Once installed, ensure all connections are secure before powering on your system. The Segotep GN-650 is designed for reliable and efficient operation.
- Power On: Flip the power switch on the back of the PSU to the 'I' (On) position. Then, power on your computer using the case's power button.
- Efficiency: The 80 Plus Gold certification means the power supply operates at a high efficiency (up to 90% at typical load), minimizing wasted energy and heat.
- Cooling: The integrated 120mm fan provides effective cooling for the power supply components. It is designed for quiet operation under normal load conditions.

6. Maintenance
To ensure optimal performance and extend the lifespan of your power supply, periodic maintenance is recommended.
- Dust Cleaning: Regularly clean dust from the power supply's fan and ventilation grilles using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Cable Inspection: Periodically check all cable connections to ensure they are secure and free from damage.
- Environmental Conditions: Maintain a clean, dry, and well-ventilated environment for your computer system.
7. Troubleshooting
If you encounter issues with your power supply, refer to the following common troubleshooting steps:
- No Power:
- Ensure the power cable is securely plugged into both the PSU and the wall outlet.
- Verify the PSU's power switch on the back is in the 'I' (On) position.
- Check all internal power connections (24-pin ATX, CPU, PCI-E, SATA) are firmly seated.
- Test the wall outlet with another device to ensure it has power.
- System Instability/Random Shutdowns:
- Ensure your system's power requirements do not exceed the PSU's 650W capacity.
- Check for overheating. Ensure the PSU fan is spinning and not obstructed.
- Verify all components are correctly installed and not drawing excessive power.
- Unusual Noise:
- If the noise is from the PSU fan, ensure it is clean and free of obstructions.
- If the noise is a high-pitched whine (coil whine), this is generally harmless but can be a characteristic of some power supplies.
If problems persist after following these steps, contact Segotep customer support or a qualified technician.
