Prototype of RTX 5090 Appears With Four 16-Pin Power Connectors, Capable of Delivering 2,400W

Or maybe it just delivers 600W without burning the ever-loving hell out of the connectors.
- Almost has to be. 2400W would put it completely outside the consumer market. Consumer PSUs don't go that high. Home power outlets don't go that high unless you have special electrical work done. I can hardly imagine what a cooling system for a nearly 3KW system would look like.
  
  In Europe, this is no biggie
  I just saw a reputable 2400W kettle on a random online store for 50€
  Looks like there are 3000W options too
  
  nVidia cares less and less about the consumer market every year. We basically only exist to buy the factory fourths so that the overall yield of any given wafer can be maximized.
  2400 for a single component is still rather insane even by server room standards. But 12 or even 18 load balanced? That starts to "make sense" for higher end data centers or even on-prem server rooms at the more tech oriented companies.
- Yup, I presume this is their answer to the cables burning. Divide the wattage between more wires
  
  The real answer to the burning cables is to divide the wattage between the six wires on a single connector, which most of the 50-series cards don't do that. That results in ~15 amps across a single scorching cable.
- They could have just used normal 8 pin connectors in that case.
That's almost 1W per dollar!
I, for one, would rather just see them use a couple of 2/0 AWG welding cables, bolted onto a 5mm copper plate on the board. If you need 200 amps, make it look like 200 amps.
- PCI bus bar on top.
With 2.4kw you can just use it as a space heater, and a strong one at that!
If they put 2x 12pin HighPower connectors and they wouldn't be burning up because each would be delivering just 300W. But they explicitely don't allow board partners to do it themselves, because NVIDIA is bunch of controlling assholes.
- They could even used it as part of marketing. “So powerful it needs 2 connectors”
Good luck plugging that into an outlet without tripping a fuse under load.
- 10A. That's fine.
  
  I'm not trying to be a 1-upper, but you need to also include the power the computer and CPU use as well. Not to mention the age of the outlet and how many times a plug has been inserted/removed from it. The contact resistance can be pretty bad depending on how old the outlet is.
Christ, not exactly a model of power efficiency is it?
Also, if it's drawing that much power, how could it possibly dissipate all the heat? It must sound like an F-16.
I expect this card will be a hard pass from me...
