Bitmain AntMiner D3 19.3 GH/s X11 ASIC.

Sold as spares or repair, but powers up all OK, a photo shows red light on.  I haven't connected to Internet hence only red light showing.  No reason to believe this wont work.  You will need to purchase a power supply and power cable.

Please do your own research before purchasing we have owned this and other miners for a few years but  only used for a few months

Purchased from Bitmain.

Don't hesitate to ask questions.
