I have been running 4090 with 13900KS (both water cooled with AIO) for 18 months now. Typical power consumption during use is around 70..80W (as measured from the wall). Max I have managed to press for under stress testing is 660W. System’s 850W power supply feels just fine, should have got a smaller one.
An electric kettle boils water in 2 minutes. This GPU will be on for hours.
You can make a slow cooked steak on it then? Looks useful!
1600-1800W in North America, because your standard outlet is 120V 18A max.
Most home offices are likely converted bedrooms. Those plugs, at least where I'm from, are likely to have 15A outlets, only.
Most of north america is still on 10 amp circuits to the breaker.
I wonder how can the per capita household electricity use be double in the US vs EU then...
A lot of extra circuits :)
Heating and AC. We use them way more than Europeans.
1 kW in Japan. Same power plugs as North America, but only 100 V.
