4. Installation Guide

Before you begin, ensure your computer is completely powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.

4.1. Package Contents

Your Aigo AT Series Power Supply package should include:

• Aigo AT Series Power Supply Unit
• Installation Manual (this document)
• Mounting Screws
• Cable Ties
• AC Power Cord (may vary by region)

4.2. Physical Installation

1. Prepare your PC Case: Open your computer case and locate the PSU mounting bay, usually at the bottom or top rear of the case.
2. Mount the PSU: Gently slide the Aigo AT Series PSU into the designated bay. Ensure the fan is facing the correct direction (typically downwards if there's a bottom vent, or upwards if it's a top-mounted PSU without a bottom vent).
3. Secure the PSU: Use the provided mounting screws to secure the PSU to the PC case from the outside rear.

4.3. Cable Connections

Connect the necessary cables to your motherboard and other components. Refer to your motherboard and component manuals for specific connection points. Use the cable ties for neat cable management.

General Cable Types and Lengths (Approximate, refer to Figure 7 for details):

• Motherboard Interface: 20+4 Pin (1 connector, ~550mm length)
• CPU Power Connector: 4+4 Pin (2 connectors, ~650mm length)
• PCI-E (Graphics Card) Power: 6+2 Pin (2 connectors, ~550mm + 150mm length)
• SATA Power: 4 connectors (on various cables, ~450mm + 150mm + 150mm length)
• MOLEX 4 Pin: 2 connectors (on various cables, ~450mm + 150mm + 150mm length)

1. 20+4 Pin ATX Motherboard Power: Connect the main 20+4 pin cable to the corresponding port on your motherboard.
2. 4+4 Pin CPU Power: Connect the 4+4 pin CPU power cable(s) to the CPU power port(s) on your motherboard. Modern motherboards may require one or two 8-pin (4+4) connectors.
3. 6+2 Pin PCI-E Power: For graphics cards requiring additional power, connect the 6+2 pin PCI-E cables. These are typically 8-pin connectors (6+2) for high-end GPUs.
4. SATA Power: Connect SATA power cables to your SSDs, HDDs, and optical drives.
5. Molex Power: Connect Molex power cables to any legacy peripherals or case fans that require them.

5. Operation

1. Initial Power-Up: After all connections are secure, plug the AC power cord into the PSU and then into a wall outlet.
2. Power Switch: Ensure the power switch on the back of the PSU (next to the AC inlet) is in the 'ON' (I) position.
3. System Start: Press the power button on your computer case to start your system.
4. Power Down: Always shut down your computer through the operating system before turning off the PSU switch or unplugging the AC cord.

6. Maintenance

To ensure optimal performance and longevity of your Aigo AT Series Power Supply, follow these maintenance tips:

• Keep it Clean: Periodically clean the exterior of the PSU and its fan grille to prevent dust buildup. Use compressed air to gently blow dust out of the fan and vents. Ensure the system is powered off and unplugged before cleaning.
• Cable Management: Good cable management not only improves aesthetics but also enhances airflow within your PC case, contributing to better cooling for all components, including the PSU.
• Environmental Conditions: Operate the PSU in a well-ventilated area with stable room temperature. Avoid placing the computer in direct sunlight or near heat sources.

7. Troubleshooting

If you encounter issues with your power supply, try the following steps:

• No Power:
  • Check if the AC power cord is securely plugged into both the PSU and the wall outlet.
  • Ensure the power switch on the back of the PSU is in the 'ON' (I) position.
  • Verify that your wall outlet is functioning by plugging in another device.
  • Check all internal power connections (20+4 pin, CPU, PCI-E, SATA) to ensure they are firmly seated.
• System Instability/Random Shutdowns:
  • This could indicate an overloaded PSU or a component issue. Ensure your PSU wattage is sufficient for your system's components.
  • Check for proper ventilation and ensure the PSU fan is spinning freely. Over-temperature protection (OTP) might be activating.
  • If you recently added new hardware, temporarily remove it to see if the issue resolves.
• Loud Fan Noise:
  • Dust buildup can cause fan noise. Clean the fan and vents as described in the Maintenance section.
  • Ensure no cables are obstructing the fan blades.
• Burning Smell: Immediately power off your system, unplug the PSU, and contact support. Do not attempt to use the PSU again.
