The place runs 32A 3-phase electric power 220v
I know that each S9 uses around 1400W
So wts the maximum quantity of S9 can I run in this place?

Thanks for your help !

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

One thing of note. The current 13.5th s9 bitmain estimates 1323w + 10% which is actually around 1450w. This is about the actual usage as I have tested them on a 94% efficient PSU.


Total power available in watts:

32A * 220 = 7040w

You run breakers at 80% of max for safety:

7040 * .80 = 5632w

Available power divided by per unit draw:

5632 / 1450 = 3.884 units

So 4 would be the max I would put on that circuit.
Stop buying industrial miners, running them at home, and then complaining about the noise.
