3. Setup Guide

3.1 Unpacking and Inspection

Carefully remove the APW7 PSU from its packaging. Inspect the unit for any signs of physical damage. Ensure all cables and connectors are intact.

3.2 Power Connection

The APW7 PSU supports both 110V and 220V AC input. The maximum output wattage depends on the input voltage:

• For 1000W output, use a 110V-120V power cable (standard 3-prong household plug).
• For 1800W output, use a 220V-240V power cable (requires a specific higher-voltage plug, typically a C13/C14 or C19/C20 connector, not a standard household plug).

Ensure you use the appropriate power cable for your electrical setup to achieve the desired wattage. Connecting the correct power cable to the PSU's input port is crucial.

3.3 Connecting to Miner

The APW7 PSU comes with 10 x 6-pin PCI-e connectors. These connectors are used to power your ASIC miner(s). Connect the 6-pin connectors from the PSU to the corresponding power input ports on your miner(s). Ensure each connector is securely seated.

For optimal performance and to prevent overloading, adhere to the power requirements of your specific miner models. For example, if using 110V input, it is recommended to connect no more than four miners that draw approximately 235W each, to stay within the 1000W limit.

4. Operating Instructions

4.1 Powering On

Once all connections are secure, plug the power cable into a suitable electrical outlet. The PSU will power on, and its internal fan will begin operating. The fan is designed to run continuously to ensure proper cooling of the unit.

4.2 Indicator Lights

The PSU and connected miners may feature indicator lights to show their operational status. Refer to your specific miner's manual for detailed information on its indicator lights. Generally, a steady green light indicates a stable power connection and normal operation.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your APW7 PSU.

• Cleaning: Periodically clean the fan and ventilation grilles to prevent dust buildup, which can impede airflow and lead to overheating. Use compressed air or a soft brush.
• Environment: Operate the PSU in a well-ventilated area to facilitate efficient heat dissipation. Avoid placing it in enclosed spaces or near heat sources.
• Fan Noise: The PSU's fan runs continuously and may produce audible noise. This is normal operation. If the fan noise becomes excessively loud or unusual, it may indicate a potential issue requiring inspection.

6. Troubleshooting

If you encounter issues with your APW7 PSU, consider the following:

• No Power:
  • Ensure the power cable is securely connected to both the PSU and the electrical outlet.
  • Verify that the electrical outlet is functional.
  • Check if the correct voltage power cable is being used for your region (110V or 220V).
• Insufficient Power Output:
  • Confirm that you are using a 220V-240V power source and corresponding cable to achieve the full 1800W output. A 110V-120V source will only provide up to 1000W.
  • Ensure the total power draw of connected miners does not exceed the PSU's maximum output for your voltage setup.
• Overheating/Automatic Shutdown:
  • Check for proper ventilation around the PSU. Clear any obstructions from the fan and vents.
  • Reduce the load on the PSU by disconnecting some miners if the total wattage exceeds recommended limits.
  • Ensure the ambient temperature is within acceptable operating ranges for electronic equipment.
• Excessive Fan Noise:
  • While some fan noise is normal, excessive noise might indicate dust buildup or a failing fan. Clean the fan and vents.
  • If the noise persists, contact support for further assistance.
