Yes, spark not arc.

Paschen's law explains a true arc threw air or a gas, but we are not really creating a Vandegraph or a Jacob's ladder or a Tesla coil for @Grim5 here at high voltage and low current to cause an actual arc threw air basically a plasma that we see as a lightning spark or a continuance arc and yes high current arcs can be created too at a lower voltages threw air but voltages a pc should not be able to generate unless faulty. The problem that I am talking about is materials vaporising from the high heat created by a bad connection (high resistance) ending up catching fire and yes sparking or arcing can occur in that environment as there is a heat source, fuel and oxygen (air) in the area that causes fire, fire is a plasma as is an arc threw air, some will say fire is a lightly ionized gas too but so far we call it a plasma, so sticking to that state of matter regarding fire, without getting overly complex and ending up looking like him below:-
So basically the issue remains that fire can occur with such failures given the right conditions. I agree these are not true arcs but most people call a spark an arc too and sparking that can cause a fire is still a fire that can cause a safety issue, which is the main topic safety and are these connectors used safe, the answer is yes in the perfect conditions but no if in a condition that can cause a safety issue like loose connections or bad joints that cause high resistance areas that cause heat near a fuel (plastic) and finally combustion in air (oxygen).
The topic really is are these connectors safe and have they so far proven to be 100% safe the answer is no and the real questions should be why are these connectors causing so much heat or the ability to arc/spark in an environment that has a plastic material that is a fuel and air around it which contains oxygen that allows combustion to happen, we all know the fire triangle, fuel+heat+oxygen = fire, the question is how did these connectors pass safety testing and then being certified safe for the general public to use and not specialised trained users only.

Weird! The AX1000 is supported but not the 1200?

Yet other adapters have bit the dust. Very interesting how they are locking threads using the standard boiler plate response instead of using alternate methods of messaging that they should post in the mega thread. This is optically a pure cluster failure on communication and reassurance to their customers. If it was their attempt to keep the discussion in a single thread they've failed massively by making it look like they are trying to silence people who report problems.
And all they had to do is change the phrase

So is this another controversy around an NV launch that will end up soon forgotten? 20 series it was failing 2080 Ti's
Not read much on this but seems to be a bit of user error around install the cable. If you're going to bend it sideways along the length then yep you're asking for trouble. Do it as NV suggests and likely no problem.......

I don’t know how Jenson finds the time to run a multi-million $ company and post on here under a pseudonym. Only explanation surely?
Jensen said it's such a huge issue that he will personally come to your house and crimp a cable Infront of you and then braid it with a leather jacket off his own back.
or so MLID claims

Jarred is more annoyed about bringing up Adapter Gate that AMD would advertise "AMD the safer choice" then the actual problem itself.
Sorry to see that mate. I am glad you took the time to do random inspections to catch it early though.Shaz12 said:I just took off my connector to take a look and I noticed a crack near one of the connectors which I am sure wasn't there before. I am putting my 3080 Ti back until I get the Cablemod cable next week.

who knew oxygen was flammableSorry this nothing to do with a 4090 but this guy had a real shock while using a can of air to clean his PC

Looks like a candle or something behind the tower caught the oxygen blast, the fireball appears behind the PC.
Those canisters are not filled with oxygen. the propellant is butane.
Once the compressed air all been sprayed. The butane is the only thing that’s coming out.
I got a bottle of the stuff. If you use it upside down then only butane is coming out and it will freeze stuff up pretty rapidly as well as making the room smell pretty nasty and a serious fire hazard if you got ignition source.
Tho not sure how that air got caught on fire.

Hmm what is wrong with it, looks fine to me,I just took off my connector to take a look and I noticed a crack near one of the connectors which I am sure wasn't there before. I am putting my 3080 Ti back until I get the Cablemod cable next week.
You can see a crack in the plastic above the pin to the left.

Nope, can't see it needs a better focused photo
I'm sure there is one but I can't make it out.
However the pins show no sign of heating at all, the sleeve will be compressed in the connector anyway and will form adequate insulation and location.

Not sure how you can't see it, plain as day here, the rest of the connectors are fine, the one circled has an obvious horizontal split\crack at the top.
