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

[Slam62]

Nah, the burnt connectors I've seen have blatantly been fitted incorrectly, all the melting was at the pin end nowhere nearnthe solder, the worst thing that would happen with solder is a dry joint or someone bending the cable so far that the solder snapped, solder is however a relatively soft metal.
If was anything to do with the solder the main structure of the connector would have melted or the solder would have lost electrical contact.
What a ridiculous discussion, don't look up

I also kind of see the pattern that "inferior" 600W boards are affected more than others.
Its mainly TUF and Gigabyte, the only inferior boards allowing 600W PL. No Strix, no FE.
Of course, Suprim X cases contradict this, but some pattern is there.

Also, it seems strange that all partner boards have worse power efficency at idle and worse transistent spikes than FE, even if they seemingly use the same power delivery with more phases(Strix/Suprim use the same voltage controller with more power phases).

This and the fact that no FE has melted seems to point to the fact that FE is still somehow using superior board layout than the rest.

Nice theory, but I have seen on the Reddit Nvidia site there was a strix and suprim user who had a melted adaptor.

Just checked my FE - looks normal.

I'll be ordering the Cablemod 90° adapter and x4 pci-e > 12VHPWR cable just incase!

there seems to be a pattern to this with no FEs being reported yet, though lets wait for the sample to reach 30-50

could just be there's far less FE's in use?

Did the AIB's cheap out on their included PCI-E adapters compared to the Nvidia ones?

 

[Tykey]

can anyone answer a query for me please?

on the cablemod website configurator, there's the option to choose a 3 x 8 pin pcie cable for "600W 3090TI or 4080" or choose a 4 x 8 pin pcie cable for "600W 4090". I have a 4090 that takes 3 8 pin pcie cables, so I assume I should specify the 3 x 8 pin on the configurator even though it says it's for a 3090TI or 4080, not 4090?

it's a possibility yeh, didn't think of that.

You can select how many PCI-E connectors you need, just make sure to order the correct version for you PSU manufacturer!

I would assume that a x3 connector would be perfectly fine for your card.

Still waiting for my EVGA CableMod cable to be despatched it's showing as expected shipping date of 6th November i placed my order on the 16th October.

 

[Canon-man]

I'd imagine they'll have quite a backlog of orders to chew through since 4090 release, and subsequent melting issue!

So there could be 2 different adapters being supplied with 4090's

One that using 150v wire that has a different pin solder setup
to the other adapter that is using 300v wire

Seems that way, I just checked the adapter with my FE as I'm not using it and it has 300V 105C wire, Jay-G25 checked his Zotac and it has the 150V stuff!

I wonder if it's more FE is the 4090 with least width and every other 4090 is a chonker in comparison so more pressure on that adapter bending against the sides of people's cases with AIBs than FEs.

Is there an easy way to check or do you have to start dismantling it?

Peel the fabric tape off (it goes back on easily) and pull back the sleeving to have a look.

Will post these in here as I have the other thread, using a cablemod cable now and plug showed no sign of burning. Tape is very easy to remove and replace to check your own

All adaptors were provided by Nvidia. Not one was making their own.

Tho not last time check it was only a handful of reported issues

I think your warranty is voided if you do that. Not sure. Worth checking

Looks like i'm on the 300V cables. Fingers crossed the BeQuiet 12VHPWR adapter gets UK stock soon though, i'll change it just to be on the safe side.

The tape looks exactly the same when you put it back on, I doubt there's a way for them to tell.
