Description
The Bitmain APW3++-12-1600-A3 is a high-efficiency AC-to-DC switching power supply unit (PSU) designed for Bitcoin and cryptocurrency mining rigs such as Antminer models (S9, L3+, D3, S7 etc.). It supplies stable 12 V DC output with up to 1600 W total power at mains voltage typically used in mining farms. This PSU features protections against short circuit, overcurrent, overheat, and low-voltage input, and includes numerous PCI-Express 6-pin connectors to power mining hash boards and control boards.
