12V 400W High Power Atx 24Pin as a replacement for Mac IISI PSU

[ironborn65]

Hi everyone,

I have three broken PSUs for my Mac IISI and I am struggling to fix them.

I was wondering, what about this toy

and adding a 12V linear transformer to feed it

I can fix the softboot with the PN2222

Is it a bad idea?

Best
