Yeah. I know. I also have that kind of setup for my kids. Or actually theres 5 gaming setups alltogether. Mine isn't primarily for gaming despite the specs.

I just wanted to point out that gaming PC setups generally consumes more than ~333W of power.

Like yours. Given numbers are estimated averages, as I can't know precise specifics.

GPU 140W, CPU 65W, MB ~35W, RAM 6W, SSD 3W, KBM 1W, Monitor 35W =280W Everything without monitor consumes about 245W. PSU efficiency is about 80% so to produce that 245W it has to draw minimum of ~306W. This combinrd with monitor's 35W sums up to ~341W, which already surpasses that 1/3kWh when playing intensive game from few years back.

And your 4060 setup while being a gaming PC isn't on a power draw scheme very average as that GPU specifically is very low power consuming. Go older, 3000 or 2000 series or up 5000 series or even any AMD, the power consumption goes up. And there are lots of older setups and even X99 setups with Xenons with up to 125W power consumption.

Yes, it is possible to have a gaming setup to run on given power consumption, but on average I would say you'll reach 1kWh within 2 hours.
