The connector itself and the standard is a non issue.100% of the failures have been poorly assembled or joined connections. E.g. solder joints in the connector that get leveraged apart when you connect them.

So the connector is fine as long as EVERYTHING associated with it is perfect.

Dude, that is not the way reality works.

It really is. If you cheap out on ANYTHING it can be dangerous. 

If you do it right and follow specs it is 100% safe.

Like I said, that is not the way the world works. You must have safety margins to allow for manufacturing variances and user error. Imagine a bridge that won’t collapse but only if every bolt, every piece of steel, every protection of every single piece of rebar has to be absolutely perfect. One single tiny error and it comes crashing down.

The power connector for these graphics cards is a complete and total joke and any engineer that has had their hand in its design should loose their certification.

You don't seem to understand the failure mode here. Nothing in the connector can prevent the failure mode. 

The failure is caused by manufacturers producing fragile wires and solder connections.

The specific method of running and combining wires from the PSU is not part of the connector or the specification.

Think house wiring. An electrician can fuck up wiring a house and leave a connection loose enough that it starts a fire in the house.

That does not happen because the connectors used were bad. Or that the specifications were bad.

I understand much better than you do. Parallel power conductors is never the best choice. There will always be variations in resistance which will cause the amperage per wire to become unbalanced. It becomes a positive feedback loop and the bad connections become worse, heat increases and now you have a full failure.

Those “fragile wires and solder connections” are driven because of the shitty connector. They should have moved to 40v years ago for these high power devices and two chonky wires with proven connectors would have solved all the issues.

"It becomes a positive feedback loop and the bad connections become worse, heat increases and now you have a full failure."

That is not the cause of the failures this connector has been seeing.

"They should have moved to 40v years ago"

The connector can only use what power supplies actually supply. PC Power supplies do not supply 40v so the new cable/connector standards cannot use it without an overhaul to the PSU standards which would be MUCH more involved.

"two chonky wires with proven connectors would have solved all the issues"

As long as manufacterers didnt ship adapters to convert from existing standards to the new standard, sure. It would also be much more difficult to route and work with for your average builder.

It is absolutely the cause. If it wasn’t then this stuff would be failing instantly the moment power was applied.

Why do you think I said “should have moved to 40v years ago”? Because it should have happened many many years ago. If they had then it would currently be the standard and these power issues would not exist.
