I got it from the storeroom at the video games company I was working for at the time. They were having a clear out, and we could take whatever we wanted. This was one of the things I wanted.
(Sadly they didn't let me have the Jaguar devkit, doubly annoying when I later discovered that Atari had put all their Jaguar stuff into the public domain. Mind you, I'd only have thrown that out too as well, probably, so same result in the end.)
Flagship GPUs like the 3090 Ti have had 450W TDPs for a while now and they work fine. It's not a new thing with the 40xx series cards.
A graphics card with its own power supply! With this weeks' news of the 4090 using 450 watts at peak, this Voodoo card puts things in perspective.
