So 15 A x 120 V is 1800 W. The problem is even in a dedicated circuit you can’t use that continuously, it’s considered dangerous.
For continuous draw you’re limited to 80% of the line’s rating (in the US). People who have looked into EV charging have certainly run into this fact.
So the computer (and sound/monitor/etc) have to stay under ~1400 watts if it’s on a dedicated circuit.
1/3rd of that for just the GPU I’d pretty crazy. I honestly wouldn’t have thought GPUs could get this high.
Also, I remember my computers being hot in a small room long ago. A lot of the space heaters on Amazon are rated either 750 or 1500 W.
I don’t think I wanna be near a computer that hot.
- midoridensha 4y agoDon't forget the PSU isn't perfectly efficient; it's usually between 80 and 90 percent. So for safety, about 1100W (for the total of the DC power draws of the components fed by the PSU) is really the maximum for continuous draw, and as you pointed out, there's also monitors, sound, etc. A typical monitor now is probably 50W or so (which is actually really good compared to the CRT behemoths of yesteryear).
