Very helpful insights! My 40W brick and 80W PicoPSU seem to work with the bare SE/30 itself, but things might change if you add upgrade cards, external floppies, and other peripherals. A beefy PicoPSU and 12V brick surely wouldn't hurt! I'll update the documentations.
This is designed for completely stock machines with CRTs.
The CRT in early Macs actually runs on 12V, that's why this simple adaptor can provide all the voltage it needs.
Just a regular 12V DC power brick, mine says 40W and runs the stock Mac SE/30 and Mac Plus just fine.
Of course you can buy higher powered bricks, they are very common so very inexpensive as well.
Hi there! I designed a few PSU replacement kits using modern PicoPSU ATX power supplies.
Currently for Mac SE, SE/30, 128K/Plus, and Apple II line.
