Is there any interest in new Amiga 3000D and 4000D power supplies?

New chasis would be made according to the same dimensions of the original.

I cant immagine there being much profit for yall making powersupplies. You most likely wont sell thousands of them, and if you did you would have to outsource the pcb production and probably the assembly, as you wouldnt have time to solder all thoes diodes and caps and other things.

We are both aware of that. Realistically looking at things, we'd probably be looking at around 100 sales, if that. I guess if we could break even in the end, it would be worth doing it.

Even if you did setup shop in your garage and made your own pcb's, what would you do with all thoes gallons and gallons of waste ferric chloride? You have to pay to dispose of it properly.

We would buy internals of existing ATX power supplies that could fit into the A3000D or A4000D chasis, and simply rewire them to work with A3000D and A4000D style power connectors, and neatly secure the PCBs inside the chasis so that the entire job looks clean. We would definitely not make our own internals of the PSUs from scratch. That would be too expensive.

I can't imagine why you didn't like my idea of using existing "REAL" Amiga PSU housings, unless you think finding the cores would be too much trouble and don't think your buyers would supply you with their existing PSU's for a source of cores.

Other than fitting the ATX PSU's into the Amiga PSU housing, fitting the fan properly and switching the MoBo connectors, what PCB are you talking about?

The original chasis for both A3000 and A4000 could certainly be improved as far as airflow holes are conserned. We figured that a completely new arrangement would be in order, thus the idea of reusing existing original chasis would not provide for a clean solution, as a lot of custom cutting would be required and we are not equipped for that sort of thing. The design of the new chasis would be done by us and the actual manufacturing would be done by a 3rd party contractor. As soon as we design the chasis and find a fitting ATX PCB, we will look for the best option on 3rd party manufacturing. The idea is to have all the parts ready for a simple assembly by the two of us, testing, and finally sale.

I think that A3000 motherboard requires tick signal to be present, and some sort of a solution would have to be provided in order for our idea to work with A3000D system in mind.

I'd definitely buy one, the 150W PSU isn't just enough to power the internal expansions/devices in my A4000D.

sorry amigadave but . . .its so difficult to understand?!?

They purchase the core of ATX PSUs and fits it in a case identical to the 3000 and 4000 one . . . wheres the mistery?

EDIT- x56h34 . . chose an Active PFC one if you can :-)

@x56h34:

If I dont remember wrong, you can jumper the A3000 motherboard to manage without the PSU TICK signal. That would require an addition to the user-instructions, but it should still be rather straightforward.

@patrik

indeed, the tick signal generator circuit, isn't really necessary for this project.

I would purchase at least one A3000D PSU. I have an adaptor cable to install an ATX PSU into an A4000D quite nicely.

Hi  Kindred of Babble-on,

As I also live in Canada I would be very interested in one for my 4000D Keep me informed on your progress.
