Amiga PSU To Meanwell

KiCad design for a PCB for a board to mount a Meanwell RT50-B PSU inside an external Amiga PSU A300/600 case.

Known case compatibility:

A300/600 Power Supply - P-No: 391029-02

Its possible that this design also works in the A1200 PSU but i don't have one to verify that.

A600 PSU Variants

There are 5 variants of the A600 PSU listed in the service manual, I have only tested the -02 variant (UK Plug), but i would imagine that all these other variants are mechanically the same, so would probably work just as well with this adaptor

PSU Part numbers:

• 391329-01
• 391329-02 - UK Plug (240V)
• 391329-03
• 391329-04
• 391329-05

A500+ PSU possibly is compatible?

From visual appearances (i don't have one to look at in person), it is possible the A500+ PSU might be mechancially identical to the A600 PSU and therefore might also be compatible with this PCB.

PSU Part numbers:

• 321503-01
• 321503-02 - UK Plug (240V)
• 321503-03
• 321503-04
• 321503-05

Parts

The PCB was designed for these connecters, by any suitable 2.54mm pitch connectors will do the job.
