Hi Guys

Im at the point where i need more power in my trusty A1200.
My case doesnt have enough space for a internal AT PSU. So i only have two options, build my own external PSU from an old AT PSU and cutting up an old Amiga PSU for the connector. OR (which the option I want to go for. Convert one of the ATX external PSU things:



The only problem is that AT power supplies had a little button but ATX power supplies dont. Any ideas how I can get an ATX power supply to work on an Amiga? I googled but google hates me and just showed me A3000 tower conversion with no help on ATX powersupplies.

Cheers guys.... u the best :-D

Amiga Powershot 1200 ME-PSHT-12 and customize this to your needs ( I assume you want to put the power board inside your 1200), I am currently investigating this option myself.  A matter of size on the powerboard.  
Or
Contact a cable supply company and ask them to make you one like
Redmond Cable   :-D
which is what I will be doing as soon as I find a powerboard that I can fit inside mine.   :-D

The powerboards support a power on switch mechanism and you can have one of those cables made also.  Review the docs that came with your power board.

Its going to be way cool when its done.   :pint:

@mantisspider cheers,

"they an american company?"  Yes, but you should be able to find someone locally.

"what powerboard will you be using?"  
I want to use an Audio Forge PW120 or 120a.  :-D

"I like these small laptop PSUs rather than the big beige amiga ones."  
 I want my A1200 desktop as a lean, mean spacesaving fun machine.

My current project is on my desktop A1200 with internal cdrw which limits my internal space more than normal.  I have some cardboard cut outs of the PSU's taken from some mates.  I am doing some plastic remolding work to add an additional inch to the upper A1200 case.  If I am successful I will be able to keep the internal floppy drive and will use the Audio Forge PW120, but if I loose the floppy then I will use the smaller square PW120a.  Either way I'm having fun.  Plus I am repainting the keyboard and will also paint the case something other than beige!    :pint:

Excellent quick fix.  Are you going to put it inside your A1200?   :-D

@Doobrey

Dr. FrankenAmigaStien I pressume?   :lol:

Sounds like you are going to need more than a standard A1200 case. Planning to use Zorro board or did you get it just for the extra Clock Ports?

@amigean

Currently mine is in pieces. but this link has pictures of one similar enough to mine to give you a look 'n see.

  A1200CD

I decided to paint the keyboard and the case.  Tired of beige.
Then the power supply died   :-o  (homemade PC power unit) so i decided I would try to fit a powerboard inside and am currently in the middle of a plastic molding experiment to increase the vented top area of the desktop A1200 top case back roughly an inch and a quarter.  I want to keep my internal floppy.  But when I am finished  I will definetly post pics.

When looking at the URL above you will notice the only way to fit a cdrom completely inside is to have it cut into the bottom case as well.  

When done (if successful) the cdrw will be mounted on the inside of the upper case only which will also give more vents and space for the powerboard and "Still" keep its portability and similarity of design to the original case.  :-D
