  1. Power consumption: Quoted figures depend on your PSUs efficiency, the ambient temperature and the accuracy of the power meter.
  2. PSU: You must provide your own ATX PSU with 1 PCI-e connector, or a power line.


Scalable: Multiple U3 miners can be maintained by one controller running cgminer due to its USB port.

Hassle free: Setup consists of plugging in the USB and power cables and running Antminer CGMiner.

Cool: U3s remain cool and quiet due to its 80mm fan which quietly exhausts air out the side of the case.

Stable and Accurate: Based on the tried and tested BM1382 chip, the U3 is extremely stable and is able to run 24 hours a day without problems.


The refined design of the U3 allow it to blend on any desk or shelf without standing out.
