No your English is quite well and thank you for the reply. The power supply that came with it I don't believe works in the USA. I am using an EnerMax 1500 watt desktop power supply
No your English is very good and thank you for your quick reply. The power supply that came with the unit does not seem to work in the USA. Therefore I am using a Enermax · ATX, EPS · 1,500 watt output · 80 PLUS Gold · Modular with 1 rail for each of the 2 miners. Entire system is drawing no more than 450 Watts and running nice and cool.
With that said do you think it still could be this power supply?
I too have a 80 Plus Gold rated power supply. Those are solid. The power draw from the specs say 430W, which is in the same ball park as your readings, so I don't suspect the problem is the power supply.
How long does the miner go down for? I had the Giants in a multi algorithm pool and I did see them blink every so often, but it was for a few seconds, less than a minute, when it switches the algorithm.
Have you tried switching to a new SD card? Make it a Class 10 or better.
