In most household shocks, you touch a conductor, and you are the resistor to ground. Your resistance is independent of the drive voltage, so if you touch a 110V wire, the current will be half of what you get with a 220V wire. So the voltage determines the current, and thus the lethality.
There’s lots of other factors that go into the effective resistance like the amount of moisture on your skin, what shoes you’re wearing, and what the floor is made of, etc, but in all cases twice as much voltage will cause twice as much current. You are by far the highest resistance element in the circuit, so your resistance will completely determine the current - most household circuits are capable of supplying 10-15A continuously, so your resistance is the current limiter.
It’s a bad idea either to go touching live wires either way, but the rule of thumb I heard was was that a 110V shock usually won’t kill you and 220V shock usually will.

That's completely incorrect though. I've been shocked by 230VAC at least a dozen times, if not more. And the fuse for the circuit absolutely should not be the limiter, the RCCB should trip WAY before the main fuse.

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.
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.

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

Good luck plugging that into an outlet without tripping a fuse under load.

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”

10A. That's fine.

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...

You would still need to run the computer off multiple plugs, as almost any 240v plug is 10a.
You'd likely need a dedicated breaker and plug, similar to a stove plug.
All UK plugs are 13A.

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.

Nvidia has been pretty shit for the last few generations but this is clearly just an engineering prototype for testing, they obviously weren’t trying to make a 2400w 5090.

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.

While that certainly SHOULD be the case, in the US at least while RCCBs (we call them GFCIs) are generally required in wet areas and perhaps for new construction, in most older houses the majority of circuits don’t have any sort of ground fault protection other than the fuse/breaker. In my current house we have them on only two outlets - one in a bathroom and one in the kitchen.

Electric companies after every nvidia gpu generation.

Wild...we don't have them on outlet-basis, it's the entire house that's protected by them, they're installed at the power-inlet to the house so everything is protected by it. And they're mandatory even on old houses.

Judges you from French 0.20€/kWh nuclear prices
If only you guys had listened to the science... You'd be gaming AND heating your place for cheap!
And regardless, unless the chip is radically different from what has been observed in currently available RTX 5090s, I don't see how 2400W can be anything other than a transient spike

Let's not start a discussion about nuclear energy here. France has enormous subvention on electricity and Germany a lot of taxes. And both countries have issues in their energy system, so yeah

France has taken away electricity subventions a long time ago, they were temporary relief during COVID only.
In fact, there are pretty high taxes here too, just the base cost is lower.
And I started this debate to challenge the notion that all of Europe has Germany's electrical management issues; they're the main ones to have failed.

don't put it past nvidia.
they gotta fulfill those unrealized promises about native 4k gaming somehow.

The nuclear and hydro over here in Canada puts us around 0.10€/kwh on average. Really wish processes for nuclear were streamlined decades ago, power would be even better now if it was

In most of the EU countries, that is fine as our sockets are mostly 16A rated. Unless you stick 2 of those GPUs in your PC
