  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

        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.

      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.

        Nominally EU voltage is 230V, and may be 240V. In fact, it can be as high as 230V +10% = 253V.

        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.

    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

    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.

      source

      • Ilovethebomb@lemm.ee ⁨1⁩ ⁨month⁩ ago

        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.

    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…

      • brot@feddit.org ⁨1⁩ ⁨month⁩ ago

        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

        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

    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??

  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.
