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

The "just plug it in correctly" crowd don't seem to understand what's at play here. If the adapter has tolerance issues, some of them will "just pug in" and others will not.

There are picture of connectors with plastic *inside* the (female) pins. Good luck "just" plugging one of those in. This would just be a defect, but it's defect that leads to a catastrophic mode of failure.

Then there's the possibility of tolerance issues. We may be telling people to force squre pegs into not-so-square holes.

I fix broken electronics for a living. I have been working with electronics my entire adult life. If this sort of problem turned up in any of the products we serviced, we would have to change that product ASAP.

"Just plug it in correctly." is bull ****.

Some of the Gigabyte 3080's had issues with the 8 pin setup on their cards because the pins had too much slop and would not line up correctly. (I had one of these cards) Ironically, the worst thing to do when the issue was encountered was to push harder as we are telling people to do with the the 12VHPWR connector now. Doings so would just push the pin back into the plastic and make for a bad connection.

However, even if end users did go full-Neanderthal with the sloppy 8-pin, the resulting modes of failure were normally just failure to power up etc. The end user could often just realign the pin and reinsert the connector...and all was well. -Because the plastic wasn't ******* melted.

Coincidence? Aren’t the adapters all supplied by nVidia?

Judging by Reddit posts, it may be down to bad tolerances. I’ve seen users saying that they pushed the cable in as far as it would go but it didn’t click. It may then come loose when bent up against the side of the case?

I think its a mix of both the adaptors being defective along with connectors on the GPU end not being designed properly. The ASUS TUF has reversed the orientation of its connector and almost no one hears a click when trying to insert the adaptor cable. Some on Reddit reported a slight gap even after it was fully plugged in. The way Zotac and the other small AIBs designed the connector seems to be easy to get the terminals connected to the pins with minimal force. There was a report on Reddit that someone's Cablemod cable was not fitting in their Asus card without a click and they had to remove the sheathe over it to get it to connect. On the other hand, it slid in very smoothly on my Zotac with a click. No pressure needed.

I guess that's why Nvidia is so silent on the issue. It would need a massive recall and a design fix on their end to get it fixed. I don't think the bend is the issue. Jony Gerow torture tested the adaptor at a 10mm bend radius and nothing happened. Its just people need to get these connectors to click when inserting them. If it doesn't then remove the card from the board, attach the cable and see if there is a gap and then install. But now you risk bending the cable horizontally when trying to install the card.

The connector just wasn't ready for widespread rollout. Nvidia's obsession with keeping the connector s compact is the cause for this beta testing.

I took one look at the horrible quality of that adapter and ordered a Cablemod within hours of getting the card. Its impossible to close the sidepanel on the case no matter how wide your case may be without putting pressure on that stiff cable which makes matters worse because they are using soldered and double seam terminals which no one in the cable industry uses. Keeping this melting thing aside, Nvidia should be sued for not selling a working product to consumers. It does not work with any case perfectly. You need a custom cable to get it to fit. Otherwise they should mention on the box that the GPU is designed for an open test bench.

Nvidia may not have a choice, American 4090 owners can now sign up to sue Nvidia

Yeh, NVidia should give all 4090 owners a revised 90 degree adapter cable, or something like that, oh, not sure why no FE have the problem thou.

The 4080 is going on sale in a couple of days and has the same connector and more people will buy it given the lower price point. Considering how even power limited 4090s saw the adaptor melt, its likely the 4080 will cause the issue to blow up even more.
 
I'm waiting on an EK waterblock and a cablemod cable for my FE, so haven't actually opened the card yet BUT I asked myself last night; would I be comfortable using the card if it was going on air cooling and I didn't have the cablemod cable.

Tbh I'm not sure I'd take the risk on air with the supplied adapter until nvidia publish any sort of investigation. I just don't trust it.
 
Ah i see, i also have a 4090FE, still sealed, as i am not sure if to send back, think i get 30 days or is it 14 days to return if this problem does turn out to be a lot worse, but i guess we have a 3 year warranty with the FE anyway don't we ?
 
I honestly think this launch has been a joke. Firstly Evga pulled out (wonder why), then the 4080 relaunch edition fiasco, now all that will be left of us is an ash silhouette were we once sat at our burning PC due to these shoddy adapters. Never mind the usual stampede of selfish scalpers you have to deal with every launch just so you can have the pleasure of vaporising yourself before anyone else.

Gpu launches are getting more and more depressing, stock is always an issue, pricing is always an issue. It's the same circus with every launch year in year out.

Yet there has been no fires, the amount of melodrama around this has been absurd.

I disagree. Putting the connector there on the 4090 would have been a disaster with case compatibility.

Disaster started from making such tiny connector for so much power/current.
I mean just look at what size bundle of wires goes to this itty bitty connector.

Unlike in old connectors, there simply can't be any safety margins/tolerances left to avoid major consequencies from the smallest issue.
