    • Great miner
Fast shipping and came in on time. PDU reads 238.5V at 16.61Amps so running 3962W.

A little higher on the power consumption but its running between 210TH and 230TH on a couple of different pools Make sure you get a PDU to plug into, I had ordered a power cord but the unit arrived with one in the box ... show more

And as I proceeded to the software side, I quickly realized that the machine was having network problems. After much research. I feel I might have a bad networking card in the computer. As of today, I still haven't got it working. :( ... show more
