amiga 2000 power supply unit

That's to exagerrate a bit.
I know for sure that my old 320 meg  drive uses far less power than my 80 gig drive.

Software Hut sells the Bigfoot 300W supplies for A2000s.  Not sure if they are complete units or you have to send them your old p/s box and they swap out the pcb inside.  You might want to call them.  The Bigfoot is VERY expensive though...

@X-ray:

It depends where you get it from. Elbox sell a nice, but kind of expensive ATX to AT converter, that is used in Mirage 4000 Pro towers. This one is made by Elbox, and it even comes with some sort of a controller chip on it, as well. You can buy it from their online store. ATX on/off switch is required, too. It connects to the power pins on the ATX to AT converter.

I'm sure that you can find similar and cheaper adapters by Googling around, or perhaps checking out eBay.
