Internal cable D.I.Y Audio server

Hello
I would like to make 2 DIY cables for an audio server
to connect a HDPLEX 400W HiFi DC-ATX converter to the MSI MAG B550 mortar motherboard

- Molex 24Pin-24Pin ATX: 30cm
- Molex 8Pin-8 Pin ATX for the CPU: 40 Cm

I would like to make them like the Ghentaudio photos in 18 AWG wires

only I hesitate between Neotech or VH audio

attached are the links of the selected cables
