Is PSU for C128 better than one for C64?

This is the picture of PSU I got with C128 I bought few days ago. I opened it to blow out the dust and was bit surprised when I saw much more components than in C64 PSU. I dont know much about PSU`s and filtration but this big choke and caps looks promising.  :slight_smile:

Optimized PSU from C64 sounds pretty good to me powering the SID, but could this PSU be better?

It has got some strange square DIN-like connector but it is not problem to change it to normal one. Only problem could be size as it is pretty big, and I wont use it if there is no any benefit compared to C64s PSU.

I would check a schematic first… the advantage of the C64 PSU is the 9v AC and 5v regulated DC are separate, so you can add 9v DC to 5v DC and get 14v DC, good for a 12v regulator. But if this PSU outputs 9v DC and 5v DC with a common ground, then you can’t do the same thing.
