Notes: The server does not contain a DC/DC converter; therefore, higher input voltage will cause higher

Mining efficiency.

2. Connecting the Power Supply

Nine PCI-e connectors are located at the top of the AntMiner L3+ for connecting the PSU as follows:

  • Eight PCI-e connectors for the hash boards. Each hash board has a set of two PCI-e connectors.
  • One PCI-e connector located on the controller.

Each hashboard must be powered by the same PSU on both connectors to prevent possible damage and instability.

To connect the power supply:

  1. Connect PSU power cable connectors to each of the eight PCI-e connectors on the top of the AntMiner L3+, ensuring that each hash board is powered by the same PSU.
  2. Connect a PSU power cable connector to the AntMiner L3+ PCI-e connector on the controller.
  3. Connect the network cable to the ETH port.
  4. To power up your AntMiner L3+, connect the PSUs to the power wall outlet.

If you are using more than one PSU, power up the PSU connected to the controller AFTER you have powered up the other PSU(s).
