5. Setup and Installation

5.1 Physical Installation

1. Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet.
2. Mount the PSU: Carefully slide the HELIOS P2-1000G into the power supply bay of your PC case. Ensure the fan is oriented correctly (typically facing downwards for bottom-mounted PSUs, or upwards if your case design requires it for optimal airflow).
3. Secure the PSU: Use the provided mounting screws to secure the power supply to the PC case from the rear.

5.2 Cable Connections

The HELIOS P2-1000G is fully modular. Connect only the cables required for your system components.

1. 24-pin ATX Motherboard Cable: Connect the large 24-pin cable to the corresponding port on your motherboard. Ensure it clicks into place.
2. CPU (EPS) Cable: Connect the 4+4-pin or 8-pin CPU cable to the CPU power connector(s) on your motherboard. High-end motherboards may require two 8-pin connectors.
3. PCIe Graphics Card Cables:
   • 12VHPWR Cable: For compatible PCIe 5.1 graphics cards, connect the native 16-pin 12VHPWR cable directly to the GPU. Ensure a firm connection.
   • 6+2-pin PCIe Cables: For other graphics cards, connect the 6+2-pin PCIe cables to the GPU power connectors.
4. SATA Power Cables: Connect SATA power cables to your SSDs, HDDs, and other SATA-powered devices.
5. Peripheral (Molex) Cables: Connect Molex cables for any legacy peripherals that require them.
6. AC Power Cord: Once all internal connections are made, connect the AC power cord to the power supply and then to a grounded wall outlet.

6. Operating Instructions

6.1 Powering On Your System

After ensuring all cables are securely connected, flip the power switch on the back of the power supply to the 'ON' (I) position. You can then power on your computer using the case's power button.

6.2 Smart Fan Control

The HELIOS P2-1000G features a smart fan control system. The 135mm fan will adjust its speed automatically based on the power supply's load and internal temperature. This ensures optimal cooling while minimizing noise during lighter loads.

7. Maintenance

7.1 Cleaning

To maintain optimal performance and longevity, periodically clean the power supply:

• Disconnect Power: Always unplug the AC power cord from the wall outlet and the power supply before cleaning.
• Dust Removal: Use compressed air to gently blow dust out of the fan grille and ventilation openings. Hold the fan blades to prevent them from spinning rapidly during cleaning, which can damage the bearings.
• Exterior Cleaning: Wipe the exterior of the power supply with a soft, dry cloth. Do not use liquid cleaners or solvents.

7.2 Storage

If storing the power supply, keep it in a cool, dry environment, away from direct sunlight and extreme temperatures. Use its original packaging if available to protect it from dust and physical damage.

8. Troubleshooting

If you encounter issues with your power supply, refer to the following common troubleshooting steps:

• No Power:
  • Ensure the AC power cord is securely connected to both the power supply and the wall outlet.
  • Check that the power switch on the back of the PSU is in the 'ON' (I) position.
  • Verify all modular cables are firmly seated in both the power supply and the components.
  • Test the wall outlet with another device to confirm it has power.
• System Instability/Crashes:
  • Ensure your system's power requirements do not exceed the PSU's 1000W capacity.
  • Check for loose cable connections, especially to the motherboard and graphics card.
  • Ensure adequate ventilation within your PC case to prevent overheating of components, including the PSU.
• Loud Fan Noise:
  • The fan speed adjusts based on load. High system load will naturally increase fan speed.
  • Check for dust accumulation in the fan or vents and clean as described in the Maintenance section.

If issues persist after performing these steps, contact GAMDIAS customer support.
