Introduction
The HAMKOT Dual PSU Cable Adapter is designed to allow the connection of two power supply units (PSUs) to a single ATX motherboard. This solution is ideal for systems requiring additional power, such as those with multiple graphics cards for gaming or cryptocurrency mining, without needing to upgrade to a single, more expensive high-wattage PSU. This adapter ensures both power supplies activate simultaneously, providing stable and synchronized power delivery to your components.

Troubleshooting
If you encounter issues with your HAMKOT Dual PSU Cable Adapter, refer to the following troubleshooting guide:
System Not Powering On:
- Check All Connections: Ensure the male 24-pin connector is fully seated in the motherboard and both female 24-pin connectors are securely attached to your PSUs.
- Verify PSU Power: Confirm that both primary and secondary power supply units are plugged into working power outlets and their power switches are in the 'ON' position.
- PSU Compatibility: Some older or specific PSU models may not synchronize correctly. If possible, test with different PSUs to rule out compatibility issues.
Loose Wires or Intermittent Power:
