Inertia, note that NEMA was developed in the early 1910s by Harvey Hubbell, who was a businessman — hence the socket is optimized to be cheap. Type F by Albert Büttner was developed more than a decade later in the mid 1920s.
Actually Type F is not that great as a plug either. It is also one of the older, overly bulky design, and predates polarity. And the shape allows you to cheat by inserting into an unearthed receptacle (e.g. CEE 7/1), and the lack of polarity makes the ground pads a shock hazard. Even with an earthed CEE 7/3 receptacle, the live pins are in contact first, while the ground pads still are touchable. There is also the additional annoyance that even within Europe/CEE 7 there is the competing and polarized Type E, necessitating that virtually all modern appliances come with an overly complex CEE 7/7.
The Swiss have developed Type J or SN 441011, which is a modern design far superior to Type F. The internationally standardized, but shape-incompatible version is Type N or IEC 60906-1, which is adopted in Brazil and South Africa.
That map doesn’t demonstrate the wattage of a given circuit, which is what’s being discussed. Voltage and frequency aren’t the focus. Computer power supplies do 100-250v 50/60hz so that’s not a factor.
If GPUs get anymore power hungry, computers are going to need dual power supplies.
More like you’ll need an actual circuit for the computer.
Most houses running 110v are on a 15A circuit.
Only in North America. The Rest of the World is neither following your measurement units nor your paper sizes, nor your low voltage standards.
And Taiwan and Japan for some reason. Never understood why they don’t use type F sockets.
I vastly prefer type F but I travel to the USA, Taiwan, and Japan the most often.
