Since I got new monitors, I had the problem that they are using powersupplys instead of power cabels. So tho solve this and dont have any powersupply hanging anymore, I constructed a small bracket to hold the and screwed it unter the Table.
I used 3.5mm x 16mm screws but you cand find the measurements in the drawing.
I hope someone else could need this.
