Setup and Installation
Before beginning installation, ensure your computer is powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge damage to components.
Component Checklist:
- GIGABYTE GP-AP850GM Power Supply Unit
- Modular cables (24-pin ATX, 8-pin EPS/CPU, 6+2-pin PCIe, SATA, Peripheral)
- AC power cord
- Mounting screws
Installation Steps:
- Prepare your PC Case: Open your PC case and locate the power supply mounting area, usually at the bottom or top rear.
- Mount the Power Supply: Carefully slide the GP-AP850GM into the designated slot. Ensure the fan is facing the correct direction (typically downwards if there's a vent, or upwards if not). Secure the power supply with the provided mounting screws.
- Connect Essential Cables:
- 24-pin ATX Motherboard Cable: Connect the large 24-pin cable to the corresponding port on your motherboard.
- 8-pin EPS/CPU Cable: Connect the 4+4-pin CPU cable to the 8-pin or 4-pin CPU power connector on your motherboard.
- PCIe Cables: For graphics cards, connect the 6+2-pin PCIe cables to your GPU. Use separate cables for each connector on the GPU if possible for optimal power delivery.
- SATA Power Cables: Connect SATA power cables to your storage drives (SSDs, HDDs) and optical drives.
- Peripheral Cables: Connect peripheral cables to any other components requiring Molex power, such as case fans or older accessories.
Important: Ensure all modular cables are securely connected to both the power supply and the respective components. The cables for this power supply are specific to GIGABYTE; do not attempt to use cables from other brands as this can cause damage.
- Cable Management: Route cables neatly behind the motherboard tray or in other designated areas to improve airflow and aesthetics.
- Close Case and Connect AC Power: Close your PC case, connect the AC power cord to the power supply, and then plug it into a wall outlet.

Operating Instructions
Once installed, the GIGABYTE GP-AP850GM power supply operates automatically with your system. Ensure the power switch on the back of the PSU is in the 'ON' position before powering on your computer.
Fan Stop Function:
The GP-AP850GM features a smart fan with a fan stop function. This means the fan will remain off during low load conditions to provide silent operation. As the system load and temperature increase, the fan will automatically start spinning to maintain optimal cooling. This is a normal operating characteristic and not an indication of a malfunction.
Power Efficiency:
The 80 PLUS Gold certification indicates that the power supply operates with high efficiency, converting more AC power into usable DC power for your components and minimizing wasted energy as heat. This contributes to a cooler system and lower electricity consumption.
Maintenance
Proper maintenance can extend the lifespan of your power supply and ensure stable system operation.
- Dust Cleaning: Periodically clean dust from the power supply's fan grille and interior (if accessible without voiding warranty). Use compressed air to gently blow dust out. Ensure the PC is powered off and unplugged before cleaning.
- Cable Inspection: Regularly check all modular cable connections to ensure they are secure and free from damage. Loose connections can lead to instability or component damage.
- Ventilation: Ensure adequate airflow around the power supply. Do not obstruct the intake or exhaust vents of the PSU.

Troubleshooting
If you encounter issues with your GIGABYTE GP-AP850GM power supply, refer to the following common troubleshooting steps:
- No Power/System Not Starting:
- Ensure the AC power cord is securely plugged into both the wall outlet and the power supply.
- Verify the power switch on the back of the PSU is in the 'ON' position.
- Check all modular cables (24-pin ATX, CPU, PCIe) are firmly connected to both the power supply and the motherboard/components.
- Test with a different AC power cord if available.
- If the issue persists, disconnect all non-essential components (e.g., extra drives, peripherals) and try to boot with only the motherboard, CPU, and one stick of RAM.
- System Instability/Random Shutdowns:
- Ensure your power supply wattage is sufficient for all your components.
- Check for loose cable connections, especially for the graphics card and motherboard.
- Monitor system temperatures to rule out overheating of other components.
- Fan Not Spinning:
- As mentioned in Operating Instructions, the fan stop function keeps the fan off under low loads. This is normal. The fan will activate when the power supply reaches a certain temperature or load threshold.
- If the fan never spins even under heavy load, ensure no obstructions are blocking the fan blades.
- Cable Compatibility:
- Only use the modular cables provided with your GIGABYTE GP-AP850GM power supply. Cables from other power supply brands may have different pinouts and can cause severe damage to your components if used.
If these steps do not resolve your issue, please contact GIGABYTE customer support or consult a qualified technician.
