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.
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).
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.
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.
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.
All UK plugs are 13A.
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.
I’m gonna oneup those kettles with >7500W showerheads
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.
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.
