"The 12VHPWR connector and terminals are a lot smaller than the previous generation, and cablemod warns that “it appears that bending the wires too close to the connector could result in some of the terminals coming loose or misaligning within the connector itself.”
Meaning
THE CABLE

Yes the only proof you have is because someone said it. Not much different with saying the fault is in the card
The saddest part is many famous tech youtubers have done some extreme bending on the cable, yet they didnt suffer the same problem. But that gotta be the problem, am i right?
Thought you guys had a previous argument somewhere and carried over.
I notice also there are talks of the 4090ti being cancelled for the moment. That's hardly surprising since the 4090 itself out performs even the very latest CPU's, the 4090ti would be even worse. Also, the reports say the 4090ti is blowing up even the largest power supplies and the heat output from it is just too extreme.
Makes you wonder if the entire 40 series is just one big NVIDIA mess.
I suppose things will sort themselves out in time.
In the mean time some vendors are supposed to be offering up to 60% off the 3090, so NOW seems to be the time to buy the last of the 3090's?
Anyway, the real meat of the consumer market has always been the mid-class GPUs. Now that the green team have already messed up whatever goes below the 4080 16GB, red team only need to price everything right and they're set for the next-gen. Although the recent Zen 4 mobo pricing has me thinking they're a bit overconfident in themselves, or that TSMC is charging them a real premium price for the chips.
I've never seen those "reports" and that sounds very made up. The only people who would have their hands on a 4090ti right now is Nvidia and maybe AIB partners. I'm sure both of which would know what the power requirements are and how to select a properly rated psu. Even if they didn't any decent psu is going to have over current protection to shut it down if you try and pull more than it can handle so they aren't going to "blow up". Also unless they are running some insane power plug set up the 12vhpwr cable is 600w and you could pull another 75w off the pcie slot in theory so 675w max, it wouldn't take the "largest power supplies" to handle that. As for the heat, they would have to do something to get way more power to the card because the 4090 at 600w runs in the mid 60c in synthetic benchmarks. My Strix 4090 gaming at 4k max settings and max ray tracing runs in the low to mid 50c range so even if they used the same cooler designs for the 4090ti they have tons of head room.
Another case.... but this time with native atx3.0 cable
Once i heard its TDP, it was game over for me. I have enough of a PSU to feed it, with Platinum certificate, but, even if that card is sold 300$, i won't use it. That much of a TDP is trouble because it is not an accumulated one, only SINGLE component using that much of power. AMD did a good job of NOT bringing 12VHPWR connector to its RX7000 cards. They continue with old PROVEN power connectors.
It can be from loose connection on either side or both side, bent pin, wrong size wire/pin, or insufficient solder.
It maybe worth to get good DMM to make sure it is good connection on the adapter while connect to the PSU.

See pinout? 12Vs and COMs must have good connections. One wire break from 12 V may melt the connector.
In the comments someone says that the msi psu was using out of spec wiring for their 16 pin cable.
