Ok, after looking at the connector from superflower, the psu side has dimples and there are 2 groves,
and the gpu side has 1 groove and i don't see dimples, but it is small enough that i could make mistake, but the front has that small triangular cutout so it looks like second iteration.
I've shown the grooves (slits) that I talk about at this.

(T-40 is for focus
)
I don't see dimples inside the connector on the gpu side.
ps thanks, cause of this thread now I know how to make photos of stuff for closeups
Edit: And I thought I could destroy something again xD and now it is not needed
Thank you very much for this contribution!
I also appreciate the fact that you didn't destroy the connector.
The picture from
post #41 wasn't clear enough but now I am at peace in this regard, the receptacles are the NTK design, 1 slit, 4 leaf spring which is regarded as the best.
On top of that I found a comment on newegg saying the same thing.

Okay now regarding the insulation and temperature rating, also addressing some things jonnyguru said.
We have to pay close attention to the details.
So he said that the
wires almost hit 80°C with a 4090. That one draws about 450W not 600W which is the cable rating.
Then he says that when he tested the cable at 600W draw the temperature at the
GPU connection (not the wires!) exceeded 80°C.
Apples and oranges much?
But okay let's assume that both areas reach similar temps.
Aris says he wants the thermistor as close to the pins as possible. Why is that? Because the point of entry on the GPU is the weakest link in the chain and there's the quickest way to catch the danger not further along the cable. The examples I've seen of melted connectors were mostly (by far) on the GPU side and regarding the actual connector, not the wires that follow it. Sure if the damage was severe the insulation behind the connector eventually melted but it all started from the point of entry in the GPU and not the floating portion of the cable getting so hot that it ignited the insulation.
Then this test here:
How we measure, and resultsSomething for warm-up. We’ll start our ATX 3.0 PSU tests with perhaps the most talked about topic surrounding them, the temperatures of the new cables with 16-pin PCIe connectors. The overview of the PSUs of twelve brands answers well the question of how the...

Different PSUs and each tested with its own cable. Similar temps for both areas in some examples although there are differences in others.
Jonnyguru says "almost 80" with the 4090, that would mean above 75, because if it was lower he would've said "almost 75". Then with a 5090 type of load it's below 85, otherwise he would've said "exceeded 85". So from 75 to 85 it's 10°C maximum, but minimum it could be only 5 from 77-78 to 82-83.
Even if we assume equal temp between the wire and connector, 5-10°C more on the 5090 compared with the 4090 is quite low, I would expect at least 15 given the power draw difference and the cable running close to max rating.
Newer 12V-2x6 cables able to handle 644W of power while partially inserted.

^Also here it's mentioned the wires get as hot as the connector. But look at the actual temps and the load compared to Jonny's claims!
In his test below, he says max temp of about 53°C, using a power draw similar to 5090 not 4090.
So which is it? Also he's using the "squid".
Also he had an exchange with a user about the temperature testing of the cables:
For Corsair we have this here:
And not much else.
I don't want to throw shade at him but I think he's confusing things, the connector is supposed to rated at 105°C, not specifically the wire insulation:
The 12v-2x6 GPU Power Bridge cleans up the cabling on Nvidia GPUs and prevents tight cable bends for peace of mind.
www.corsair.com
About the insulation, the only mention I've found is Igor's article which then lead to a GN video.
These are linked in his website page with the connector test above.
These tested ones are all "squid" adapters, the wire is 14AWG not 16, and indeed they are rated 105°C, but from further reading online it appears that insulation type is also correlated with wire type. So are 16AWG cables really supposed to be rated at 105?
Looking at 8 pin VGA/PCI-E cables I see 16AWG 80°C 300V on them, and the 12VHPWR to 2x8 pin cable is basically two 8 pin cables terminating in this connector, so why would the wires be different than regular 8 pin?
I am taking a gamble but I say he is confusing things.
Owners of Corsair PSUs could help us in this matter, I have searched high and low online for a close-up picture of a cable (the wires not the connector) and to no avail.
The cable that I'm talking about is CP-8920284. This is bare, I don't know if there are markings on it to be honest, I found one picture where it looks like it has markings but it's not legible.
At least Super Flower is honest, it doesn't hide anything, the cables could have easily been given a matte coating, sleeving or some shit to cover up the markings, no?
How do we know other vendors are using 105°C cables, are they marked?
Jonnyguru is basically swimming in PSUs, can't he gather cables from each one, put them on a table and take photos? He could clear up this situation within the course of an afternoon.
Why would Super Flower be so stupid as to gimp the cable by cheaping out on the wire insulation?
The connector has the best receptacles, why would that be paired with wires having subpar insulation?

Well apparently not.
With the arrival of PCIe 5.0, the ENERMAX 12VHPWR adaptor cable can deliver up to 600W of power to the latest graphics cards.

Lo and behold, the same cable, so much for SF being an outlier.
But yeah, specifically the nzxt c1500 and c1200 I linked to him seemed to have his approval.
The hwbusters review is positive.
But what about the cable?
Because the only issue with the SF was the cable, how can you make sure that a different PSU has a 105°C cable assuming this is really a thing?
How did no one cover this topic during these years? Not him, not Aris, not GN, not Igor, not Roman, no one, reddit comes out empty when searching for this.
I think we started a witch hunt, but there's no witch in sight.
If he wants to be worthy of his legend status he should step up and clarify, I'm sure he has the stockpile and gear to prove whatever is needed.
It's easy to sit in his ivory tower and hurl loogies at everyone, if he wants to contribute something valuable and help the community he should step up.
That's why nVidia got away with this shitshow, because the experts did not work together to cover all aspects and direct criticism at nVidia and other parties involved to enforce full standardisation of this garbage connector/cable not just parts of it.
