Antminer S9 w/ Bitmain APW3 PSU on 110V @ ~1550kWh, what is the kWh at 220V?

[jimbo637]

I have an Antminer S9 with Bitmain APW3 PSU using it at 110V - Based on Killawatt I am around 1550kWh.

Is it worth it to have an electrician convert it to the 220V? What would be the kWh at that voltage measured from Killawatt? I am trying to see if it would be cost effective, thank you.

Always worth it to run on 220v. It's not the wattage it's the amperage. If you're really pulling 1550@110v that's ~14amps. Run that same wattage at 220v and you just reduced the amperage to 7.045.

Thanks for the quick reply, can you help me understand why it is worth it to lower the amps?

You need to switch to 220v because you are pushing your power supply well past its rated 110v limit and it will not last very long like that.
