Setup
Pre-Installation Checklist
- Ensure your computer case has adequate space for the power supply (dimensions: 6.5 x 5.91 x 3.35 inches).
- Verify that your motherboard and components are compatible with the power supply's connectors.
- Turn off and unplug your computer from the wall outlet before beginning installation.
- Discharge any static electricity from your body by touching a grounded metal object.
Installation Steps
- Mount the Power Supply: Carefully slide the power supply into the designated PSU bay in your computer case. Secure it with the provided mounting screws.
- Connect Essential Cables: Connect the 24-pin ATX power cable to your motherboard. This cable is permanently attached to the power supply.
- Connect Modular Cables: Identify the necessary modular cables for your components (e.g., CPU, GPU, SATA devices). Plug these cables into the corresponding ports on the power supply.
- Connect to Components: Connect the other end of the modular cables to your motherboard (CPU power), graphics card(s), SSDs/HDDs, and other peripherals.
- Cable Management: Route cables neatly to improve airflow and aesthetics. Use the included Velcro cable ties to bundle cables.
- Final Connections: Ensure all connections are secure. Plug the AC power cord into the power supply and then into a wall outlet or surge protector.
- Power On: Flip the power switch on the back of the power supply to the 'ON' position. You can now power on your computer.

Operating Instructions
EVGA ECO Mode
The EVGA 750 GQ features an ECO mode switch on the power supply unit. When ECO mode is enabled (switch in the 'ON' position), the power supply fan will remain off during low to moderate loads, providing silent operation. The fan will automatically activate when the load increases to maintain optimal temperatures. When ECO mode is disabled (switch in the 'OFF' position), the fan will operate continuously, regardless of the load.

Maintenance
Proper maintenance can extend the lifespan of your power supply and ensure stable performance:
- Dust Removal: Periodically clean the power supply's fan and vents to prevent dust buildup, which can impede airflow and lead to overheating. Use compressed air to gently blow dust out of the unit. Ensure the computer is powered off and unplugged before cleaning.
- Ensure Proper Airflow: Make sure your computer case has good airflow and that the power supply's intake and exhaust vents are not obstructed.
- Avoid Overloading: Do not exceed the power supply's rated wattage. Overloading can reduce efficiency and lifespan.
Troubleshooting
If you encounter issues with your EVGA 750 GQ power supply, consider the following common troubleshooting steps:
- No Power:
- Check if the AC power cord is securely connected to both the power supply and the wall outlet.
- Ensure the power switch on the back of the PSU is in the 'ON' position.
- Verify that the 24-pin ATX cable and all other essential modular cables are firmly seated in their respective ports on the motherboard and components.
- Test the wall outlet with another device to ensure it is providing power.
- System Instability/Crashes:
- Ensure all modular cables are correctly and securely connected. Loose connections can cause instability.
- Check for proper ventilation within your PC case. Overheating components can lead to instability.
- If you are experiencing random shutdowns, it might indicate an overloaded PSU or a faulty component. Consider reducing the load or testing components individually.
- Fan Not Spinning (ECO Mode):
- If ECO mode is enabled, the fan is designed not to spin under low loads. This is normal operation.
- If the fan does not spin even under heavy load with ECO mode off, or if the system is overheating, contact EVGA support.
If these steps do not resolve your issue, please refer to the Warranty and Support section for further assistance.
