3. Installation and Setup

Follow these steps for proper installation of your EVGA SuperNOVA 1000 G3 power supply.

1. Prepare Your System: Ensure your computer is powered off and unplugged from the wall outlet. Open your computer case to access the power supply mounting area.
2. Mount the Power Supply: Carefully place the EVGA SuperNOVA 1000 G3 into the designated power supply bay in your computer case. Secure it using the provided mounting screws.
3. Connect Modular Cables: Identify the necessary cables for your components (motherboard, CPU, GPU, storage drives). Connect one end of each required modular cable to the corresponding port on the power supply.

4. Connect to Components: Connect the other end of each modular cable to your motherboard (24-pin ATX, 8-pin EPS), CPU, graphics card(s), and storage devices (SATA power). Ensure all connections are firm.
5. Cable Management: Utilize the fully modular design to route cables efficiently, improving airflow and aesthetics within your case.
6. Connect AC Power: Plug the AC power cord into the power supply's AC inlet and then into a wall outlet or surge protector.
7. Power On: Flip the power switch on the back of the power supply to the 'ON' position. You can now power on your computer.

4. Operation

The EVGA SuperNOVA 1000 G3 is designed for reliable and efficient operation. It features an ECO mode for optimized fan control.

ECO Mode

The ECO mode feature allows the power supply fan to remain off during low to medium power loads, resulting in silent operation. The fan will automatically activate when the power load increases, or the internal temperature rises, to maintain optimal cooling.

To enable ECO mode, ensure the switch labeled 'ECO' on the rear of the power supply is in the 'ON' position. To disable ECO mode, set the switch to 'OFF', and the fan will operate continuously.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your power supply.

• Dust Cleaning: Periodically clean the power supply's fan and vents to prevent dust buildup, which can impede airflow and cooling. Use compressed air to gently remove dust. Ensure the power supply is off and unplugged before cleaning.
• Cable Inspection: Occasionally check all modular cable connections to ensure they are secure and free from damage.
• Environmental Conditions: Operate the power supply in a well-ventilated environment with ambient temperatures within the specified operating range (0°C to 50°C).

6. Troubleshooting

If you encounter issues with your EVGA SuperNOVA 1000 G3, consider the following common troubleshooting steps:

• No Power: Ensure the AC power cord is securely connected to both the power supply and the wall outlet. Verify the power switch on the PSU's rear panel is in the 'ON' position. Check all internal cable connections (24-pin ATX, EPS, PCIe).
• System Instability/Crashes: This could indicate insufficient power or a faulty component. Verify that your system's power requirements do not exceed the PSU's capacity. Ensure all cables are properly seated.
• Fan Noise: If the fan is excessively loud outside of high load conditions, ensure ECO mode is enabled if desired. Check for any obstructions in the fan or vents.
• Power Supply Tester: Use the included power supply tester to verify basic functionality of the PSU independently of the system.

If problems persist after performing these steps, contact EVGA customer support for further assistance.
