Hi fi power supply for CD-ROM????

[Flavio88]

I would like to use a CDROM as a cd player using the digital out.
With the pc psu everything correctly works but I would like to realize a good power supply(not switching)
Would someone like to give me some audio power supply schematics?
Ah, obviously the tensions are +12 and +5

Thanks

P.S.: sorry for the English😀
