#3Why can’t they just use a cable+socket similar to PSU - wall socket? It’s not even multiple-kilowatts range.

#4It's strange how Nvidia just doubled down on a flawed design for no apparent reason. It doesn't even do anything, the adapter is so short you still have the same mess of cables in the front of the case as before.

I was under the impression it saves them money. Is that correct?
It is also a powerplay. By potentially introducing a PSU connector AMD and Intel do not use they abuse their market power to limit interoperability.
Plus probably some internal arrogance about not admitting failures.

#6If we’re going to keep up these kilowatt scale cards, we’re just going to need higher voltage rails on PSUs. I had a bunch of similar dumb power connector problems when my 4090 was new.

That connector (C13) is rated for 15 amps. That's 180W at 12V.

It's 12V, which means the currents are very high (like >40A). It feels like perhaps they need higher voltage power supplies.

Arrogance is good. Accelerates the "forced correction" (aka cluebat) process. NVIDIA needs that badly.

So heat depends on current, not on power. My research: https://www.reddit.com/r/ElectricalEngineering/comments/15xf...
