Overview

The AntMiner L3+ is Bitmain’s newest version in the AntMiner L3+ series. It boasts a state-of-the-art BM1485 custom-made chip. All AntMiner L3+ miners are tested and configured prior to shipping to ensure easy set up.

Power supply unit is not included. Please provide your own ATX power supply.

AntMiner L3+ Components

The AntMiner L3+ main components and controller front panel are shown in the following figure:

Specification

The miner does not contain a DC/DC converter; therefore, higher input voltage will cause higher Mining enfficiency.

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).
