I was searching in the bitaxe shops and this one have at least something: https://silexperience.company.site/Alimentation-Bitaxe-Hex-12V-p706506766 if anyone already test or buy some PSU and could recommend, I am all ears.

If it's a ready to use product, I will totally buy it. Normally you can only bought the PSU and then you need to wired the adapters.
