Some of my friends liked the C64 PSU that I build for myself. Here’s the link.

And let’s first figure out the power consumption of the C64 from the Wiki page.
https://www.c64-wiki.com/wiki/Power_Supply
As we know the C64 needs 5v DC and 9 V AC to operate, even though 5V is enough to start the computer but you’ll lose some parts of it. (e.g. SID chip & sound)
I have been using my home built PSU for a while so I can say the parts that I used in it is enough. The power that it needs is:
5V DC -> 2A
9V AC -> 10VA
So I will use a meanwell power supply for 5V and an ordinary transformer for AC 9V
The AC transformer will be the one like below:

And for 5V power supply I will use this one:

Then I will need a box to put them inside

I’ll put a power socket and a rocker switch and a voltmeter on top to check the voltages
A DIN-7 socket for the C64 power connector:
