My motherboard isnt getting any power

Hi i am using the be quiet dark base pro 900 rev.2 case and i have the asus rog x570 strix-e motherboard.

My psu is the dark power pro 750w.

 

Now to the issue.

 

The case has a wierd psu mount. You mount the psu then plug a psu cable that is connected to the case (and has also an intigrated switch) to the psu. And then you plug the psu cable into the case and plug it into the electricity spot

 

Now i did that and connected the 24pin everything from the case and the 4-pin on the top right. I flipped both switches (the one on the psu and the one on the case). But the rgb from the MB does not start to glow and my system wont boot so my mb isnt getting any power.

 

Any ideas onm what i am doing wrong?
