Yup, I presume this is their answer to the cables burning. Divide the wattage between more wires
Comment on 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.

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.

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

Oh! I knew European outlets operated at higher voltage, but I didn’t know the standard circuits supported such high current. Jealous!

It’s the same current but double the voltage

I live in a 50 year old house. All the breakers are 16A, so 220V x 16A = 3.5kW
The electric sauna does three-phase @ 400V. My energy tracker usually peaks around 9.5kW when it’s heating.

3600W is the maximum a power socket is rated for and the fuse triggers at 3800W. So, cutting it pretty close.
lemmylommy@lemmy.world 1 week ago
I wouldn’t use that kind of power continuously. AFAIK the sockets are supposed to handle 16A for at least six hours, when they are new. When charging your car on Schuko sockets it’s good practice to limit it to 10A and check for the socket temperature after a while. Also, any connections in the cabling can have increased resistance with age and heat up with heavy continuous use. That shouldn’t matter that much when running a kettle or toaster for a few minutes, but charging a car or gaming for hours can become a problem.

I think the typical limit is around 3600W, with 16A at 230V

What about the rest of the computer though?
dabaldeagul@feddit.nl 1 week ago
3840W per breaker. Minus 2400 leaves 1440W, for a CPU, the minor components, and monitors/other equipment. In theory it could work.

Just imagine the costs of running such a system on European energy prices. We’re at ~0,35€/kWh here in Germany currently. That means that an hour of running this will cost you 0,84€. Add to that the energy use of the CPU, mainboard, Monitor and you’re paying well over 1€ per hour of gaming.

Judges you French 0.20€/kWh nuclear prices
If only you guys had listened to the science…

Standard US outlets can’t deliver 3000 watts.

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.
