Description

I had a Macintosh LC II with missing power supply, so I bought a compatible Meanwell RPT-60A and designed an adapter with mounting holes, the IEC plug and power switch.

Note that this plastic print isolates the PSU, so you should ground the PSU board directly. See the yellow wire in the picture that ends above the monitor connector in the shielding.

This is a dangerous design! The original PSU is enclosed, but unfortunately, there's just not enough room to do so with the meanwell. Use it only if you know what you are doing.

Fusion 360 design attached.
