Key Features

• Military-Grade Components: Capacitors and chokes pass demanding tests to achieve Military-grade Certification, ensuring durability and longevity.
• Dual Ball Fan Bearings: The fan bearings are designed to last up to twice as long as traditional sleeve bearing designs, contributing to extended product lifespan.
• Protective PCB Coating: A specialized coating protects the Printed Circuit Board (PCB) against moisture, dust, and extreme temperatures, enhancing reliability.
• 80 Plus Gold Certification: Achieved through the use of Japanese capacitors and other premium components, this certification signifies high power efficiency, reducing energy waste and heat generation.
• ATX 3.0 Compatible: Compliant with ATX 3.0 guidelines and includes a 16-pin PCIe cable capable of delivering up to 600W of power to PCIe Gen 5.0 graphics cards, supporting modern high-performance GPUs.
• Fully Modular Design: Allows for tidy cable management by enabling users to connect only the necessary cables, reducing clutter and improving airflow within the PC case.

Setup and Installation

Before installing the power supply unit (PSU), ensure your PC case is compatible with ATX form factor PSUs. Always disconnect the main power from your wall outlet before beginning installation.

1. Mounting the PSU: Secure the PSU into the designated bay in your PC case using the provided screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards or upwards depending on case design).
2. Connecting Main Power Cables: Connect the 24-pin ATX motherboard power cable and the 8-pin (or 4+4 pin) CPU power cable to their respective ports on your motherboard.
3. Connecting PCIe Cables: For graphics cards, use the appropriate PCIe power cables. This PSU includes a 16-pin PCIe cable for PCIe Gen 5.0 graphics cards, capable of delivering up to 600W. Connect this cable to your compatible GPU. For older GPUs, use the standard 6+2 pin PCIe cables.
4. Connecting SATA and Peripheral Cables: Connect SATA power cables to your storage drives (SSDs, HDDs) and optical drives. Use peripheral (Molex) cables for any other components requiring them, such as case fans or older accessories.
5. Cable Management: Utilize the fully modular design to connect only the cables you need. Route cables neatly behind the motherboard tray or in designated cable management channels to improve airflow and aesthetics.

Operating Instructions

Once all components are securely connected and the PSU is mounted, you can power on your system. The ASUS TUF Gaming 750W Gold PSU is designed for efficient and quiet operation.

• Power On: Ensure the power switch on the back of the PSU is in the 'ON' position. Press the power button on your PC case to start the system.
• Fan Operation: The Axial-tech fan design optimizes airflow and minimizes noise. The fan may operate at low speeds or remain off under light loads for silent operation, increasing speed as needed to maintain optimal temperatures under heavier loads.

Maintenance

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

• Dust Removal: Periodically clean dust from the PSU's fan and vents using compressed air. Ensure the system is powered off and unplugged before cleaning.
• Protective Coating: The PCB coating provides protection against environmental factors like moisture and dust, reducing the need for frequent internal cleaning.

Troubleshooting

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

• No Power:
  • Ensure the power cable is securely plugged into both the PSU and the wall outlet.
  • Verify the PSU's power switch is in the 'ON' position.
  • Check all modular cable connections to ensure they are firmly seated in both the PSU and the components.
• System Instability/Crashes:
  • Ensure your PSU wattage is sufficient for all your components, especially high-power graphics cards.
  • Check for proper ventilation within your PC case. Insufficient airflow can lead to overheating, which may cause instability.
• Excessive Fan Noise:
  • Clean any dust buildup from the fan and vents.
  • Ensure the PSU is not under excessive load, which would cause the fan to spin faster.

For persistent issues, consult the ASUS support website or contact their customer service for further assistance.
