> Previous well-designed video cards used the technologies I described. Eliminating the sense circuits and fusing is a recent development.
My point is that the PCB is where such features would be present, not the connector. There are connectors that have fusing. The UK’s AC power plugs are examples of them. The connectors inside PCs are not.
Oh, sure, I’m not proposing that the connector itself should have those features, rather that it shouldn’t be used without them present on the device.
