After numerous articles, explanations, and follow-up tests, today we’re taking a different approach. I have three intriguing topics for you: the possible origin story of the 12VHPWR connector…
That will be on another level of pain. The 75w limit is safe and does not require rework. Having motherboards designed to deliver 200-300W on a slot would be very messy and very expensive.
And probably require a connector similar to EPS12V near the PCIe slot, which would be messy. My “genius” solution would be putting a power connector on the other side of the board, directly behind the PCI-e slot. Probably creates other issues on top of the expected ones.
The real fix is probably to go back in time and have PCI-e 3.0 revamp the power delivery to allow more than 75W to come from the slot.
And where would that pcie slot pull its power from? That’s right, another connector somewhere on the motherboard. You’d just be moving the issue elsewhere.
they should probably not make gpus that use that much power. clearly, they are going over board with the chip size. to the point where they are charging 3x the price of what a flagship card used to cost a decade ago. if they do something like that you can’t fault the standard, they should come up with their own solution that works if they go overboard like that
The final answer is nvidia fucked up and should of used 4 8 pins for the 4090 and there’s no other answer
Just adding more and more 8-pin connectors is not a sustainable solution.

Motherboard has way more room for connectors and power circuits than a GPU.
Neither is adding more and more power. The real fix is making them more efficient.

Reminder, the 3090 FE used two 8-pins and was a 350W card. If they were going to use 8-pins on the 4090, they could have just used 3 at 450W.
It wouldn’t hit 600W as the current 4090 does but it would still have more headroom than the 3090 did.
