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

[x56h34]

A local Amigan/friend of mine and myself are considering designing and producing new replacement power supplies for Amiga 3000 and 4000 desktop version computers. The idea behind this project is to provide direct replacement products of the same form factor of the original PSUs (according to original Commodore dimensions) however with more power than the originals provide...probably somewhere in the area of 300W, or perhaps more. The internals would actually be an ATX power supply that would be small enough to fit inside the original case dimensions.

The complete, final product would look externally exactly the same as the original Commodore power supplies.

Installation of it would require the user to simply swap the new PSU with the old Commodore one (by removing just a few screws). We would also review options on providing a more superior airflow (especially in the case of A4000 PSU) so that hot air could be sucked in from the inside of the case and blown outside more efficiently, compared to the original Commodore PSUs.

Please keep in mind that the status of this project is extreme work in progress. At this time we are basically gathering information on whether or not there would be enough interest in such a product so that we could justify investing into its development. There is no deadline or schedule of any kind yet. :-)

Any comments, suggestions, price range ideas, etc. would be appreciated. :-) Please post them in this thread for everyone to see and discuss, rather than sending PMs. Thanks.

I would buy one or two from you if:

It can power the cyberstormppc as I already tried 6 atx models and a few at ones with no or partial succes.
I am now back to powering my amiga with an original psu off the desktop which is the only one which does cold boots short after each other.

It also should have decent wiring to the powerplug(thick enough wiring).

The powerplug itself should be of enough quality(maybe some brass contacts?)

There should be a cable with a connector for a fan(cyberstormppc/cyberstorm040etc.) 12V and 5V

The pricerange I would like to see would be around 50 euro each for a quality psu.

Interested ONLY if the PSU was swicthable between 110/220 volts 50/60 hz

This is to supply those people whom live in PAL countries with 240v/50hz power grids.... like me in Oz :-)

Will the new PSU generate a tick signal like the original commodore PSU's ??

Could you also built PSU for an Amiga 1200/500/600? This will be great.

[x56h34]

The PSU would definitely be able to power any A3000/A4000 system with an accelerator card in it (CSPPC or not) + tons of more expansions.

It would most likely be universal, 110V/220V 50/60hz switching PSU, rather than locked to a particular region's voltage.

The A3000 version would have to have some sort of built in tick signal circuit. AFAIK, this would not be needed for the A4000 version.

A500/A600/A1200 PSUs of higher wattage are not planned at this time. I think that http://www.montek.com still sell some AT PSU to Amiga (500/600/1200) conversion cables. These would do the trick with very little effort, other than producing a more expensive custom made PSU altogether.

I read in a previous thread that A3000s and A4000s don't need a more powerful PSU. Are you sure there are cases where this is necessary?

[billchase]

I would buy one.  I honestly feel that my 3000 with CyberstormPPC
is more responsive with a bigger PSU.  Keep us informed and good
luck with the project.

I would buy a few!!

I've been installing 300w AT psu boards inside the stock A4000 cases for years,works well but is a tight fit. the best thing is you can't tell it from the original psu,since its the same case

its not easy finding AT psu boards to fit,they all need a few minor mods.

Absolutely. I'd happily buy one from you. It would be nice if the cables could also be made as slimline as possible (aka rounded single cable design) given the limited space in the A4000D for example.

I just purchased a Cyberstorm MK1 040/40 with 128MB RAM, a Voodoo3 PCI, Mediator, NIC and sound card so obviously if I am willing to dump a wad of cash on my miggy skimping on a new PS shouldn't be an issue. May even buy a spare.

I'd also be interested in a new A3000D PSU if the price was right... Good luck with the project.

Count me in!
My A4000D must be like a sauna inside since the case is quite warm on the outside so a PSU with better airflow would be great! then I would dare to fit a CS PPC inside  :-P

Suggestion:
It would be cool to have some power management features included, at least being able to switch it off. I guess this would need getting a signal from somewhere...

[MrZammler]

Count me in too.

I would like to suggest something: try and get a nice low-noise fan in there. In my miggy, being that it only has one fan, it would be easy to make it the quitest machine in my room.

[Amigaz]

mmm...the A3000D sure is noisy, when turned on it sounds more than my Dual Xeon PC which has 5 fans in it  :-o
