Title: Amiga 1000 Power Supply rating
Post by: orange on December 12, 2007, 09:09:10 PM

How many watts/amperes can A1000 PSU provide?

500mA in 12V
1A in +5V
0.1A in -12V

 Total: 12.2W

 Weak, huh?

I see; yes, pretty weak.

Guess I shouldn't attempt running a590 on it, oh well..  :roll:

I used to run a half-filled CBM 2058 8mb RAM board and a Trumpcard SCSI controller off the 1000's power supply. I did use a separate power supply for the hard drive....

The A590 has its own PSU, so it will work with no trouble at all.

Well, no problem to modify the A590.
Then use the power from the zorro bus.


As you can see in this guide:

That sounds more like the 1200 power supply. I couldn't find a sticker on the 1000 supply I looked at, but the UL sticker on the case says 2A, which would imply something like 200W. I suspect it's closer to 100W.

Hi Again :)

Look at this picture at "The big book of Amiga Hardware"
http://amigahardware.mariomisic.de/index_e.html

I have no direct link to the picture.

Click on "Amiga models and clones"
Then on "commdore A1000"
And click "Image of A1000 with lid off, showing motherboard"

80Watt power
+5v 8A
+12v 1A
-5v 0.25V

As I can see on the picture.

Note:
This is a 220-240V power..
I'm Not sure the 110V power have same spec.. but I think so.

so, will the hack that BuzzBrain mentions work or not?
seems +12V might be problematic

Well, I gona try. :)

The A590 power have these spec:

5v 3.0A
12v .085A

And a A500 power have these spec:
5v 2.5V
12v 1A
-12v .01A

And I know you have external HD cabin outhere with HD and RAM, without external power.

So if you find a low power SCSI drive, you should be safe.. I think.


Sorry for my crap english.
