Hi,
there used to be a large power supply for the Amiga A500, A600 & A1200 called the Bigfoot.
I looked on the net to see if I could find some details for you but they seem to be non existent, they do appear in eBay occasionally that's where I got mine from.
The PS were advertised in the Amiga magazines & were powerful enough for expanded Amiga's with PS problems.
I think they were 350Watt supply with a monitor power output.
