Give me all you got... i am a Hulk, it makes me even stronger. Anyway, no... hate is not the absence of love, it is "love gone wrong".
How Nvidia made the 12VHPWR connector even worse.

Actually, even more insight related to the matter. Indeed, i think, after a lot of research the 3090 TI Founders Edition (or comparable, MSI used the same parts on a custom PCB, even with some own improvements...) was a very good and sturdy design... and in my mind a card that is designed to potentially last an eternity, one of the most reliable designs ever made on any GPU. Even the cable is probably not a issue there, not even at 450 W load because the power (the card is demanding) is distributed along the cables pretty well and it is as well not going above 450 W, another "security factor" limiting some potential odds. Even the controller is the top notch class, so in general it will prevent the card from getting burned in term of any malfunction.
However... unfortunately the quality of the design kinda has been depleted on the 4090 already, which has been proven and validated by a repair tech°°°... someone doing repairs on those GPUs with a totally unbiased view, but it was still working out in a "OK-manner" on the Founders Edition versions (and some more... dependable on the manufacturer).
Now... with the release of the 5090 the design and its security seems to have depleted even more... and i only point at the Founders Edition now as i got very few stories related to other designs and their quality. I can not even say if this is a sheer quality issue but to me it is clearly visible that the design is very "cramped" in order to put as many parts into a small PCB as possible... and on top of that even trying to "save up" on some parts with some critical functionalities, such as able to distribute and balancing out the power input in a good manner. It is the most pricey "consumer card" ever made, so i simply do expect a more mature design and a higher reliability... and not a prototype with a somewhat lean design.
°°°According to my judgement "KrisFix" is currently the most competent repair technician but "Northwestrepair" should be very competent as well. KrisFix was actually the one "judging" my 3090 TI design and he said "very good"... which is pretty rare if he is saying it in such a direct manner.
Anyway... a high price does not necessarily mean "better" or "more reliable" but with decreased pricing the risk of getting a bad design is in the same manner increasing, as those parts simply got a certain price and no one can afford (except Nvidia, Apple, MS and some other megacorporations... yet they are not doing it) to sell stuff "at a loss". Although, Nvidia is CERTAINLY NOT making losses... i guess this is clear to everyone.
It is not that the 4000 series are any better, as they all seem to lack current balancing, although, they usually need way lesser power vs. a 5090 or even a 4090... and most 4090 owners use very "beefy" PSUs and expensive wires... so in general it takes a lot for making something going very wrong or at least it takes years up to the point the material is slowly aging and becoming more vulnerable to design-issues... and no one knows at what time it may happen... this is the nasty thing.
3090 class cards are as far as i can tell pretty safe here as they usually will not exceed... in worst case... 150 W a cable... which is in line with the odds which may happen in a 3x8 PIN design (7900 XTX or alike).
The PSU CAN NOT make any load balancing as long as it does not have a separate rail (means it will run in a serial, not parallel condition) for every single power cable going to the GPU. Which would be very expensive and such a PSU surely will cost double the current price asked, for the same quality. Almost no one is going to pay it... so this stuff have to be handled by the extremely expensive GPU... in theory... in practice it seems to become a rarity.
At least we all can boast about AI and how great it is... despite such serious flaws in the background.
Perhaps we will see such a PSU at some point but less than 1% of all users will be buying it, making it a prestige object with very low profit, unless sold on the server market for 10 times the usual price asked.
