In the UK we have 13A sockets in every room. So that's 220x13 = 2860W in total for a ring.

I guess I could plug it into my Kitchen's electric cooker ring. That's rated at 20A (4400W).

One use of the PSU would be to power a peltier cooler. I can see it being useful to some people.

Skulltrail, SLI, multi Peltier would almost certainly need more than 1Kw

Hah, how fake is that PSU, it's just 2 PSU PCB's they put in one double-height enclosure, so you might as well just buy 2 PSU's and that way have more options in placement.
People would probably be better served with a small box that sits between the 20(24) pin connectors of 2 PSU's and the motherboard and syncs the 'power good' and 'switch on' signals, which could be made for 15 dollar, perhaps by sharkoon or some such.

In the US you can't pull 2KW from the wall without tripping a breaker, and that ignores efficiency of the PSU. Clearly there is a marketingasaurus loose that needs to tasered and brought under control.

Just so you know, in the movie theater I work at, the smallest screen takes 3kw just for the lamp. The most powerful can take a 6kw bulb. These things are bright enough to cause severe vision loss if you look at them directly while they are powered on. It's like having an arc-welder in there. Do we really need anything like this power for a HOME COMPUTER? Do we really need to rewire our homes for this? Do we really want to have a dedicated air conditioner for it?
