This Nvidia GeForce RTX 5090 gaming PC build is the most powerful ever built

This gaming PC was a CES 2025 showcase build, powered by an RTX 5090 GPU, AMD Ryzen 7 9800X3D gaming U, and a $7,100 InWin PC case.

Nvidia didn't just unveil its powerful, next-gen graphics card at CES month – it also showed off the first ever Nvidia GeForce RTX 5090 gaming PC build. This incredibly powerful PC was a one-off build to celebrate the RTX 5090 and show off its potential, showcased in an incredibly unusual (and very expensive) PC case.

This InWin Infinite PC case it sits in. Gorgeously lit up with green RGB LEDs, this gaming powerhouse also uses a top-tier AMD gaming U, giving it specs that no other gaming PC on the market can currently match.

Built by custom PC builder Mellow Mods, this "Blackwell Infinite" gaming PC was showcased during Nvidia's CES announcement for the RTX 50-series. The specs and build process were shared via a post on Reddit and in a YouTube video, which you can watch above.

It isn't just an Nvidia affair, however, with the Samsung 990 Pro NVMe SSD for storage.

As you can expect from these kinds of specs, this is a power-hungry beast, with the Corsair HX1200i providing 1200W to give both the GPU and U some breathing room. Standard gaming specs aside, the build offers a few intriguing surprises, including voice-activated smart glass that opens the case up on demand.

I'll it that I was pretty sceptical of the InWin Infinite PC case when I first wrote about it, describing it as looking "a lot like a shoe." Mellow Mods has shown, however, that with the right specs and add-ons, this highly unusual (and hugely expensive) case can elevate a normal PC build into a piece of art, and I think most gamers wouldn't turn it down if they were offered it themselves.
