Whoops?: Cablemod 12VHPWR cable also melts

MonstroMart:

Still feel like part of the problem is how big those cards are. They barely fit most midle tower cases. Often the cable has to be squeezed for the card to fit. I have a Corsair Airflow 4000D and looking at how big most 4080 are they would hardly fit in my case. Sqeezing the cable to fit the card surely doesn't help.

Bad PCB design. Look at the PNY RTX 4070 Ti XLR8, it has the connector at the traditional 92mm width, while the card itself is 120mm.

I brought this one off amazon and it works fine and is super easy to plug in all the way too. https://www.amazon.co.uk/dp/B0BN1F9HJX?psc=1 I've had it installed over 3 weeks now and I've checked it once or twice just to be sure and no melting at all.

That does look tough....5 star in the reviews too https://m.media-amazon.com/images/I/71PRadcOLBL.jpg

I would never go over 200W TDP on a GPU so I think I'll be fine even if forced to use this POS in the future.

It doesn't really matter which material the cable is made from especially if the cable/gpu socket has any electrical arcing going on since arcing can melt even metal.

@Astyanax we know you're very smart and we're just poking fun at you!....Love ya Brother! public service announcement: if you do not hear a click while inserting the connector you have done something wrong! https://i.ytimg.com/vi/FIhWsN4Jktk/mqdefault.jpg https://www.pcworld.com/wp-content/uploads/2022/12/12VHPWR-melted-adapter-cable-reddit-2.jpg?quality=50&strip=all https://www.techpowerup.com/img/bZGYXqrL0XFxGxrs.jpg https://cdn.wccftech.com/wp-content/uploads/2022/10/NVIDIA-GeForce-RTX-4090-Graphics-Card-16-Pin-Connector-Burned-Melted-_2-555x740.webp https://i3.wp.com/pliki.ppe.pl/storage/5018b773d1d970a24f42/5018b773d1d970a24f42.jpg?resize=780,470 user error^......Loooool

When does PCI-SIG update the design, i know intel wanted those 4 sense wires but the old 12pin nvidia used in the 3000 series didn't have this issue.

Yeah, sure, blame the electrican because your 2400w electric frypan wasn't plugged in all the way and it melted the terminal and burned your house down. Ignorance is User Error. Lying about it is fraud.

the connector is so shallow and the contact area so small that if its backed out just a few millimeters it melts, Pretty crap design IMO, even if it is user error , things this expensive should really be designed so that a gorilla can insert it reliably without fault.

It is Intels design.

4mm is by no means a small gap, and enough to melt 8pin pcie too.

TimmyP:

This cable must have been designed after the GPU was, and power requirements were re-assessed.

3090Ti had the same 16p connector and didn't have these issues.

Astyanax....I told you not once/ but twice to stop promoting that connection. you really are looking like you work for ""fill in the blank"" If I were you I would crawl under your rock and shut the fuk up. your intelligence level is going downhill fast with every comment you make. https://www.pcworld.com/wp-content/uploads/2022/12/12VHPWR-melted-adapter-cable-reddit-2.jpg?quality=50&strip=all

All i know, im not touching this generation of nvidia GPU, sort your shit out ppl, im not gonna burn my house down. Yes fire risk is minimal but the saying "dont play with fire" is not outdated, it will never be.

At this point, what's supposed to happen? That they move away from that new plug? I doubt it. That they somehow improve quality control and all's well? Maybe helps with newer cables and graphics cards (with cables included), but the old cables are all possibly compromised. At this point, it's literally taking your overwhelming positive chances, yet with a 1% risk or so.

This connector is without a doubt here to stay, it will see revisions but that's about it.

There will likely be guidelines established for card vendors on clearance around the connector, and that'll be all.

Don't worry, I've never acknowledged the judgement of common rabble anyway.

This theory seems a lot more plausible than the "blame the user" narrative. I don't buy the theory that all users are dumb and somehow forgot how to plug a connector. https://hardforum.com/threads/nvidia-rtx-4090-power-connectors-melting.2022862/page-12#post-1045557219

All the users made a human error and suffered because of it, Frgmstr, like always is out of his depth and making up narratives to encourage more ignorant disillusion. These connectors do not get "HOT" unless there is a issue with electron's passing between conductive surfaces, The Plastics do not "Expand and push out" of a fully clipped in connection.

4mm is bs , more like ~2-3mm since the total insertable length is only like 7mm, and the pictures dont show the "melt line" below the half way point. its a small gap by any reasonable standard, can you imagine how ridiculous it would be if your kettle would melt the outlet if the plug was backed out 3mm?

Yeah I don't think plastic expands at high temperatures, it just becomes elastic/soft and eventually melts and yeah I agree that if the connector is making proper contact the temperatures inside the connector should be around 30 degrees and that is fine. But what if a few adapters out there have bad tolerances and don't make proper contact even if fully seated ? Or bad tolerances that will not properly clip the connector even when fully inserted ? That will cause high temps and probably cause these issues. If human error was the only explanation I think we would have also seen these issues on the 3090s.
