I wouldn't buy one after watching these and have, period. The rest are beta testers, now two generations in of failure and still lining up in tents.
Instead, a proper standard should be developed.

What was “wrong” is that enough people are willing to pay exorbitant prices for the highest-end gear that Nvidia can do most anything they want as long as their products have the best numbers. Other companies do make products with lower power draw — Apple in particular has some good stuff in this space for people who need it for AI and not gaming. And even in the gaming space, you have many options for good products…
We must be thinking about very different types of games, because even though I’m completely bought into the Apple ecosystem and love my M3 macbook pro and mac mini, I have a windows gaming PC sitting in the corner because very few titles I’d want to play are available on the mac.
I would love to get some insight from Nvidia engineers on what happened here. The 3 series and before were overbuilt in their power delivery system. How did we get from that to the 1 shunt resistor, incredibly dangerous fire-hazard design of the 5 series? [1] Even after the obvious problems with 4 series, Nvidia actually doubled down and made it _worse_! The level of incompetence here is actually astounding to me. Nv…
Maybe having cards drawing >500/600 watts is just a bad idea. Add in a CPU and such and we’re quickly approaching the maximum amount of power that can be drawn from a standard 12 amp circuit continuously.

If the new 12V-2x6 connector was incompatible with the old 12VHPWR connector, they should have (and would have) made it physically incompatible. They didn’t. You cannot blame the user for doing something which is specifically allowed by design.
> You cannot blame the user for doing something which is specifically allowed by design. We really saying this when swapping a PSU to a different PSU and reusing existing cables that all look and plug in the same fries your build. I think it's utterly absurd that this is the case but that's PC components for you.

> I think next gen we will begin seeing 24V power supplies to deal with this. May as well go the whole hog & jump to 48V. (50V is as high as you can go whilst still being inside the “low voltage” electrical safety regime in most countries IIRC.)
Then the graphics card would have to have a transformer on it to step down to the voltage that the chips can handle.

I would assume a company like NVIDIA wouldn't make a power limit specification mistake, but cheap ATX power-supplies are cheap in every sense of the word.
Have a great day =3

At these wattages just give it its own mains plug.
> At these wattages just give it its own mains plug. You might think you're joking, but there are gamer cases with space for two PSUs, and motherboards which can control a secondary PSU (turning both PSUs on and off together). When using a computer built like that, you have two main plugs, and the second PSU (thus the second mains plug) is usually dedicated to the graphics card(s).

If only we had connectors which could actually handle such currents. Maybe something along the lines of an XT90, but no Nvidia somehow wants to save a bit of space or weight on their huge brick of a card. I don't get it.
> If only we had connectors which could actually handle such currents. The problem isn't connectors, the problem (fundamentally) is to share electric connectivity between multiple conductors. Sure, you can run 16A over 1.5 mm² wires, and 32A over 2.5 mm² (taken from [1], yes it's for 230V but that doesn't matter, the current is important not the voltage). And theoretically you could run 32A over 2x 1.5 mm² (you'd end…
> Alternatively each 12VHPWR pair could get its own (!) DC-DC converter down to 1V2 or whatever the GPU chip actually needs, but again that also needs a bunch of associated circuitry.
So as you say, monitoring multiple inputs happened on the older xx90s, and most cards still do it. It's not hard.
Multiple DC-DC converters is something every GPU has. That's the only way to get enough current. So all you have to do is connect them to specific pins.
Derbauer and Buildzoid on YouTube made nice informative videos on subject, and no it is not "simply a user error". So glad I went with 7900 XTX - should be all set for a couple of years.
I had two AMD 7900 XTX and they both overheated like mad. Instant 110°C and throttle. Opted for a refund instead of a third GPU.
