Question about PCI slot power

I have a Asus z590-p and want to pair a 1050ti and a rx550 in the x16 slots, the board has no extra board delivery socket lile some high and boards. Will every card be able to pull 75w or is the 75w shared, also is the power delivery with a 11900k enough? The PSU won't be the problem, 1200w titanium. I just want that the GPUs don't choke on power.
