Everyone talks about the power connector but I haven't been convinced the connector itself is the problem. This article even specifically says that the connector was plugged in all the way. If the hardware and/or firmware doesnt cut off when it detects power problems, that's the actual problem. The connector may expose the issue, but it's not the main problem.
There are many examples analyzed by gamers nexus and der8auer and the connector seems to be designed in a way that it simply is hard to properly connect, the bandaid solutions are software monitoring and visual helps
The connector certainly doesn't help, but if a single point of failure causes this, it's not JUST the connector. Allowing that much power to be able to run through a single pin is problematic. Houses have multiple forms of protection for outlets. This whole setup seems to have none.
Im no electrician but from what I remember it just needs to be slightly off and that causes a big imbalance in the lanes which leads to heat and something melting which only makes it worse, der8auer even sells parts to help with this and monitor the distribution and connection with logs and everything, so really does seem to be the connector and lack of anything checking the power
