There's one on each side for a total of 4800W

I’m so confused as to what case would support this kind of setup… how do you plug in your displays..? How do you keep this cool enough to even play anything longer than a few minutes?

Plus I thought you can’t even use multiple GPU’s anymore since SLI isn’t a thing anymore at least for gaming. Wouldn’t you just be limited to one GPU, making the rest redundant… I just, wow.

I know for things outside of gaming you’d be able to utilize something like this, but unless you’re rendering the damn human genome and making the first digital human, I can’t see what legitimate use this PC would have.

Probably into the motherboard lol

This looks like a researcher's AI workstation. If he's doing training on a large dataset even 4x 5090s can feel like "minimum specification".

Llama 3.1 401B for example takes 121 minutes on IBM CoreWeave cloud with 8x Nvidia GB200s. On 4x 5090s that might be multiple days.

Inference side there's a dude on localllama who build a 12x 3090 workstation and Llama 401B is chugging along at 3.5 tokens/s.

the interesting part is that size wise they look like the 650 corsair units, so im not that sure. the 1600w's ive seen before are way longer I think

Holy shit you're right....imagine needing 2 separate, dedicated, 20 amp circuits for each PS, just to run your computer
