Z440 ATX adaptor

So I got myself a Z440 MoBo wanting to upgrade from my Z240

I know I need the ATX adaptor. Im struggling to find a scheme or description on how to wire one myself. I do have all the hardware.

Have any of you wired your own? Care to share the pin configuration? Or if you have one of these pre-made adaptors, could you share a picture showing which wire goes where? This is for the 24 to 18pin

My project will end up in a nice Chieftec 4U rack chassis. 🥰
