Which only comes into play if you are careless, and don't connect it properly. If the connector is properly seated in the first place, there is no difference.

That is simply not true. Once fully seated, people have been able to pull it out enough to be dangerous. That same thing can happen just due to vibration, moving the case, working in the case, etc. In other words, normal behavior.

The latch is there exactly to prevent this, but it clearly doesn't (always), which is a design flaw, not user error.

And a good design has multiple failsafes, which they are now implementing with the shorter sense pins.

Which is why the problem almost disappeared after GN discovered the source of the problem, and it was widely communicated. Then most people started paying better attention to plugging them in properly.

Except that what you are saying is a falsehood, as GN put out their video in 2022, and there have been plenty of cases in 2023, like:

https://www.reddit.com/r/nvidia/comments/132wlid/another_burnt_4090_fe/

Frankly, it's utterly ridiculous to even think that more than a fraction of 4090 owners have seen the GN video.

Latched cables inside a PC don't work themselves loose. That's just nonsense.

Hindsight is 20:20. No one was complaining about sense pins length when they debuted in the 3090 Ti, or the lack of them when the previous 12 pin in the rest of the 3000 series.

But again, all the new sense pins do is guard against poorly seated cables. If you take care to make sure your cable is properly seated, you are as safe as having the sense pins.

(deleting your links to make post readable).

Those links mostly seem to be an issue with those odd Cablemod block adapters, which cablemod admitted are problematic. IIRC it's also Cablemod that was responsible for dump of accumulated cards at the the repair channel that spawned this supposed resurgence in this problem...

They wouldn't need to see the video, but since the video it's been widely communicated across the internet, that plugging it in properly is VERY important. But naturally some people would be unaware so it wouldn't completely eliminate the problem, but has drastically reduced it. If not awareness what do you think cause the reduction?
 
Depends on variety of factors, incl the connector/adapter quality and consistency of manufacture. Mine is tight fitting and can never wiggle out.

When the first reports of melted connectors surfaced, it was within first few weeks of the 4090's release. Then owners were told to ensure the connectors were fully inserted. Then reports of melted connectors magically disappeared for several weeks or months. They then resurfaced with the Cable Mod adapters which accounted for nearly all the new cases.

Again, it's already been established that in some cases, the latch doesn't actually hold in the cable very much.

And it's just a fact that vibration can loosen cables and that computers vibrate (mechanical fans, after all)

That's total nonsense. A V8 piston engine might shake these connectors loose, but not a tiny electric fan.
 
Due to cablemod's pseudo-recall of their right-angle adapter I replaced their adapter today.
It was still latched, gremlins had not worked the connector loose and there was no damage to pins on either side.

It was ugly anyway, the new solution (3 x 8 pin to right-angle 12vhwpr) looks better.

T, FTFY.

Already posted why this is a terrible idea:

ASUS starts making GPUs with no power connectors

Oh hell no. Instead of 50 cent PCIe connectors, we're now going to add hundreds of dollars to motherboards for connectors and circuitry because it needs to handle 600W. Instead of a case fans dealing with the heat from PCIe connectors, we're now going to sandwich it behind the motherboard tray...

No. I'm not whiny weak minded worry-wart that cowers with others in overblown fear.

Update 6 weeks later: strong minded @AdamK47 is still perfectly safe, no trace of smoke or fear.

Meanwhile, reddit user Byogore just witnessed the result of his weakness:
Always made sure that the cable had no bends / pressure and that it's fully pushed in, yet it still happened. At least it has a warranty until late 2025 so I'll already be on the 5090. Just glad my I was next to the PC, who knows.. maybe the house could have caught on fire from this.

I bet he gave in for just one second: "what if it's not safe". One second of lost focus, and the demon took over.

Yep, the card gave him a nice one year anniversary present.

RTX 4090 has a meltdown after proper installation and only one year of use

Just when you thought it was safe to use your 12VHPWR cable with your RTX 4090 again, another incident of GPU meltdown pops up in the forums....

Again, a ticking time bomb. Once these warranties start running out we'll see the real meaning of the problem.
