The APW3++ is a high performance power supply, meant to deliver 1600w at 220/20a full time. The L3+ version of this device has 18 connectors, enough to power two L3+ devices. Note: It can only power one Antminer L3+ miner if it is connected to a 110V mains power supply. To power two Antminer L3+ miners with the APW3++, it must be connected to a 220-240V mains power supply. Please check the mains power supply that is the standard in your country. The power cord is not included.
