Houses should come with a separate "Gaming PC" circuit breaker and power plug just like your dryer or oven. /s
The issue is internal: because the top PSU rail is only 12V, high-power devices (mostly GPU) need to push very high amperage totals. And because PC internal layouts, they can’t do that through large wires with huge connectors.
Also a legacy of cheap friction fit.
I was wondering where you'd get that from, and then I remembered that you're probably american so your baseline is only 1800W, in which case... yeah that's true. If you're installing a really powerful PC in the US you probably want either a dedicated circuit or a 20A circuit (or both).
In North America, you cant pull 1800W continuous either, it is limited to 1440 by regulation.
"This regulation is called the maximum continuous load, which is 80% of the total wattage computed. "
This is why space heaters and such are 1200 watt.
So while 120v * 15A is 1,800W no electrician would wire a setup like this.
if you need 1800W they would use probably use a 20A circuit and wiring rated for 20A. 80% load of this would be 1920W.
NOTE: Not an electrician.. if i am mistaken please let me know.
...in areas that use 220/240V. In north america appliances are limited to around 1500W, because the mains voltage is 120V.
Those machines ran 24/7 for at least 36 months before I had to start servicing stuff like GPU fans and heat sinks.
This stuff can be designed NOT to melt the dang 6 pin 12v rail

Kind of like some 3d printers have.
