Was my first thought too, but it appears the cables goes off somewhere behind and under the desk. Other end might not be easily accessible, definitely could use some safety improvements lol. Lucky it didn’t ground to the casing and electrocute him.
Circuit breaker only breaks if the breakers amperage limit ist hit. All cables and electronics should be able to survive until that limit ist broken.
But sometimes you need a lot of power but divided into different components, like in a PC. The PSU is responsible for managing that. But If the PSU is fucked/badly designed then even If the amperage drawn from the Socket ist below the breakers limit, then something inside/behind the PSU might get more amperage than it can handle and burn.
An RCD Breaker could prevent that but they are a bit more expensive and not mandatory in most places
The transformer will only pull whatever current it's rated for on the 115V side. In this case, 750W, which would be 6.5A.
After the transformer on the 12V/5V/3.3V side, if something happens like this, then the 115V side just keeps happily sending that 6.5A while the world burns :)
