Check Your 4090's 12vhpwr Connectors To Make Sure They are in Pristine Condition

Yes, spark not arc.

Not exactly. You can get arcing on a high-current 12V circuit, but it happens because because there's enough inductance that trying to interrupt the circuit causes the voltage to increase high enough to break down the air. Or, in the case of that 24V (two 12V batteries in series) welder you posted, the current is high enough to vapourise metal, forming a conductive plasma. That isn't going to happen with any 12V connector in a PC.

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.

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

All new post regarding adapter failure should be reported *here* where Nv will investigate each on a case by case.

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.......

Oh yeah thats definitely it! It's such a non issue nvidia are looking into it and are contacting people who have posted about it. But for sure, it's all about the Jelly at not handing over £1700 for a gpu. I'm so jealous i didn't get the opportunity to do that, i woulda given them £1800 just for the "privilege" and let Jensen come plough the Missus for a few hours.

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.
:rolleyes:

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.

Sorry to see that mate. I am glad you took the time to do random inspections to catch it early though.

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.

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.
