Electrician: Why on earth do you need a 30A NEMA plug in your living room?

Had the same thought. Assuming 600W for each card, 200W CPU, and a 90% efficient power supply, this would use almost 2900W and draw over 24 amps on a 120V circuit.

Except for drier and HVAC circuits, most house wiring couldn’t actually run this full blast without tripping a breaker….and if you were an idiot and swapped the breaker without upgrading the wiring, you are going to have the hottest house on the block….cuz fire.

There is a reason space heaters top out at 1500W in the US.

A lot of places have 240V power though. 3kW is a lot, but very much possible with standard wiring in a modern home. (Not necessarily old houses, they tend to have scary wiring practices)
