Hey dude, great build. I do ML work myself. I just want to take a moment to for quick advice on your build. You seem to be using daisy chain 8 pins. This will work, but you are flying close to the sun in this configuration.
Those 3090s will pull about 350 watts max each. 75 watts comes from each pcie express slot. That leaves 550 split between 3 8 pins, or roughly 183 watts each. They are rated for a max of 150 watts.
This is one of those rare situations where you might actually push the cables or your motherboard pcie too far. They are built to a much higher standard than just the rated max, but you are already in the range of potentially being 20% over without overclocks.
Be safe and get yourself some custom cables that are made specifically for your exact psu model. It'll look better too. Win win.

Damn, that looks cool. Could I ask what you use those gpus for?
