Do you have any idea how the PCIe 16x slots are usable for more graphics card (let say 75W per slot)?

The point is, is there (without the additional PCIe 6pin, typically part of WS MB) sufficient power for PCIe 16x slots?
MB has two 8pin EPS12V (for Epyc 7xx2 claims maximum TDP about 225W + 16 RDIMMech is enough), but their documentation explicitly mentions the use for CPU and MEMORY.

I’m not sure if the N cards (75W each) can rely only on the ATX24. ATX24 contains only two pins for 12V (6-7A/pin it’s lousy 180W).
