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,

      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.

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

              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.

            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).

                  when you do need power you need a special circuit.

                  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.

                  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.
