The NVIDIA GeForce RTX 5090 is one of the most power-hungry graphics cards in the world. With a base TGP of 575W, you need a very powerful power supply to run it. However, the latest leaked prototype of the RTX 5090 suggests it could have been even more demanding. Four Power Connectors for More Power https://twitter.com/yuuki_ans/status/1926903505274433943 According to the leak that includes a photo of an early prototype of the RTX 5090, this version of the card had no less than four 16-pin power connectors. This setup would allow the card to draw up to a shocking 2,400W of power,
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
Oh! I knew European outlets operated at higher voltage, but I didn’t know the standard circuits supported such high current. Jealous!
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.
Nominally EU voltage is 230V, and may be 240V. In fact, it can be as high as 230V +10% = 253V. Higher voltage means more power for a given current, so nominally it’s 16A x 230V = 3.68kW, but you could have say 16A x 250V = 4.0kW.
If your sauna is 400V then it sounds like you’ll be 230V (400V / sqrt(3) = 230). But the voltage can also be 230V -6% = 216V, so 220V is within scope.
But yeah, standard voltages in the EU are either 230V/400V or 240V/415V. They’ve been harmogenised, but if you look at the numbers you’ll see the trick - 230V +10% is roughly the same as 240V +6%. So the range is 230V-6% and 240V+6%.
You’ve got a 3 phase connection though so you might find you’ve got different single phase breakers on different phases (eg lights on one phase, sockets on another), with slightly different voltages for each one.
Most are actually 230V which is even more at standard 16A, 3680W to be precise.
Countries that use 110V have so many weird limitations that we don’t even know in Europe. For them, 230V is the “special” outlet for special purposes.
Actually, in the US the outlets are often wired with 1 leg, while giving 2 legs gets you back to 240v.
110 is probably better in terms of general safety (which is good because our houses are death traps), but it means when you do need power you need a special circuit.
We should have both more common, but the plugs are terrible (basically they turn the left prong 90 deg).
We also have a standard socket and a high power socket.
Expect our normal outlets provide 230V 16A 3.5kW (3kW sustained) and the typical high power outlets outlets provide 400V 30A 11kW or 400V 60A 21kW.
Which is why typical electric stoves here use 11kW and typical instant water heaters use 21kW.
Though probably the most noticeable advantage is in electric car charging.
Yeah, in Sweden I charge our plug in hybrid off 240, it’s pretty quick and you can use any outlet.
The giant round connectors are weird BTW, with all the holes, trying to sort that out for faster charging.
I don’t think we should run 100+ volts everywhere, we need to standardize on lvdc in most places (basically usb-c or so) with 100v only in kitchens and places you need it, because it’s more dangerous and can cause fires more easily.
Eh, not really. There is no significant difference in safety between 110vac and 230vac. Voltage is not the (most) dangerous part, it’s the amps that kill if you’re electrocuted.
Amps are voltage over resistance (I = V/R), volts absolutely matter, the human body has a decent resistance and the higher voltage helps burn through that.
It’s the same current but double the voltage
And wiring is typically rated for current limits not voltage (within reason). Some 12 gauge wire doesn’t care if you’re pushing 12V, 120V, or 240V but is only rated for 20A.
The easiest way to think about it is that the conductor is rated for the current, and the insulator is rated for the voltage. Now, once you get into the nitty gritty, they’re more intertwined than that, but it’s close enough for a surface level explanation.
The installation in my home follows my country’s regulations as they were ~15 years ago. It’s divided into several circuits, the ‘general use’ outlets one is rated for 25A in total AND at any point, ie you could plug a 5750W appliance in any of those outlets. The lights circuit is the lowest rated at 15A, still letting you ‘plug’ up to 3450W.
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 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.
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
I’m a little jealous of you guys, but we have mostly maxed out our potential in Europe for hydro power already…
What about the rest of the computer though?
3840W per breaker. Minus 2400 leaves 1440W, for a CPU, the minor components, and monitors/other equipment. In theory it could work.
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.
Here, plugs are 230V and 16A = 3680W. Not quite as much as I thought (most extension cords seem to be rated for a bit more, which makes sense), but definitely enough to run monitors of the same breaker.
All UK plugs are 13A.
3600W is the maximum a power socket is rated for and the fuse triggers at 3800W. So, cutting it pretty close.
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
Standard US outlets can’t deliver 3000 watts.
That’s why I started my sentence with “In Europe”
But I live in America so naturally you’re referring to US outlets, right??
Yes, your are right, here is a map of Europe where you have chad power plugs in a-Murika (outside these towns only virgin plugs):
God forbid I supply information. I’m fucking done commenting with all you over sensitive weirdos who think everything is a fucking argument.
I’m gonna oneup those kettles with >7500W showerheads
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.
