If Amigakit doesn't stock them, you can always ask 1985BMWK75 on here. They were recently selling the same thing for various Miggy's through this thread (http://www.amiga.org/forums/showthread.php?t=37738)

Hope this helps and good luck!

Amiga 2000 needs like the Amiga 3000 the Tick Signal which is not present on ATX power supplies.

@DJBase

But changing a jumper is enough to avoid requiring it. I know people with ATX PSUs inside their A2000 and also inside their A3000.

This seems like a good place to ask my question.

I have an A4000T which has quite a bit of stuff in it:

Cyberstorm PPC 060/233 and 128mb RAM
PIV with Concierto and Paloma
16mb mobo RAM
CD and floppy
2 x DKB3128 (96mb on one and 128mb on the other)
Kickflash + Subway USB
Compact Flash/IDE adapter with a 512mb CF card
1 9gb wide SCSI HD
1 1gb SCSI (Seagate)
1 4.3 GB SCSI (Quantum Fireball)

And another DKB3128 on the way, also fully populated.

Currently this is on the original Amiga PSU, but I have also got a spare NOS equivalent PSU

I have an ATX to AT adapter cable, a generic one bought at the computer shop.

Will this be okay to use, and what ATX PSU should I get in terms of output?

Those ATX AT cables are ok, I use one in my A4000T too. Your PSU should have enough Ampere on +5V and +12V. Modern PSUs have here usually more than 20A so thats more than enough.

I can get a 350W PSU for £7.
The rest are higher, 350W should do, yes?

Yes, should do his job.

Is that a question?  ;-)

Confirmed: 350W ATX (bought today at the computer fair for £7) with the AT to ATX converter works fine. On A4000T it is plug and play.

The funny thing is, I was searching through my boxes for a toolkit and at the bottom of one of them I found a 350W ATX power supply. That was the one from my first PC case.
I forgot I had it, what a dufus, eh?  :roll:
