    • Great miner
Fast shipping and came in on time. PDU reads 238.5V at 16.61Amps so running 3962W. Could easily change some setting on the miner to get it lower but with the increase in hash rate not going to bother. 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

    • Machine not working property. Wrong power cords were sent.
The machine was delivered in good condition, and the packing was excellent. after unpacking. I quickly realized the wrong power cords were sent. They sent two 120 volt power cords, and they should have been 240 volt power cords. I ended up purchasing my own cords. I was able to get the machine up and running. 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
