Waiting for an electrician to run 220v subpanel in my mining location. Currently all I have available and unpopulated is a 20a 120v circuit. I'd like to run 2xDPS-1200 on it, each powering 3xS3, but I know that may be pushing the PSU a bit hard given 120v input. Have any of you ran something similar?
No problem whatsoever for the PSU. But the circuit can't handle it, or i would but at "overload", over the 80% continuous load rating. Since 120v * 20a = 2400 * 0.8 = 1920 at the wall continuous load limit. Assuming you actually get 120v.
You can do it and its probably not dangerous. But if you want to stay under the 1920watt at the wall limit, you would not have to underclock a whole lot since 6 S3 could pull something like 2130watts, or you could run 5 S3 on it and forget about it.
