This auction is for 2 Bitmain L3+ with 1 psu. The 2 L3+ run off of 1 power supply using 1350 Watts. These units have custom firmware with no Dev fee that allows undervolting to run the miners at about 650-675watts each while producing about 500 Mh/s each.
In this configuration only 1 power connector from the power supply is connected to each hashing board.
2 Ethernet connections are required, one for each controller.
The power supply is recommended to run on 220 volt power.
You can also underclock more to use less power.
You could also overclock but you will need an additional power supply so that you have one power supply for each miner.
No power supply cord or ethernet cables are provided, but if you request them I can provide them for an additional charge.
These miners are cleaned and tested prior to shipping.
Free Shipping in the continental (lower48) US.
