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,
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.
