Expensive power supply, or cheap welder? 😄

When you need that much power, you would be better off with a workstation or server chassis that has multiple power supplies.
This requires a 20 amp circuit. So GPU manufacturers are going to start forcing upgrades to circuit breaker boxes/house wiring to keep up with the GPU arms race.
Edit: i wasnt prepared to do math that early in the morning. This requires so much electricity, i am starting to think it runs off of two c19 plugs in different 20 amp circuits at 110v. 16amps (the 80% safety threshold of a 20a circuit) can only deliver 1760 watts of electricity. 16a*110v=1760w.
So this either requires a 30a-220v circuit for a fucking dryer or this is bollocks. Apparently c19s can do up to 250v at 20amps so 16a*220v=3520w. People this is nuts!
You can run one of these in the UK on a 13A fuse, since our domestic supply is 230V. That's the most allowed on a single plug, though.
The more common household items that use 13A fuses are kettles and "three bar electric fires", which should let you know how much heat these fuckers are going to be pumping into your room. Going to be able to heat a large room in winter when this thing is flat out.

4x or more 3090s is a pretty popular homelab setup, heh. I've seen janky ones with like 7 mixed 3090s/3060s. This actually makes some sense.
It's absolutely bonkers that AMD/Intel won't just sell 'normal' folks tons of VRAM on GPUs instead, but, well... they don't want money I guess. And of course Nvidia's not going to do it.
