How much does it cost to have an electrician wire up 240v circuit just to power the thing?

The machine I’m describing works just fine on a dedicated 15A 120V circuit.

5x3090 in 1600W?

1800W is the max on a 15A circuit, but yes, it’s usually under 1600W. For LLM inference, limiting the TDP to 225W or so per card saves a lot of power, for a 5% drop in performance.
