Amiga 4000 3000 2000 power supply replacements

[bjjones37]

Is there a list maintained somewhere of the ATX power supplies that can be used as a suitable replacement for the original ones?  I have an Amiga 4000 and a 3000 and a 2000.  They still have their original power supplies and I am hesitant to turn them on after all I have read online.  Also I recently purchased a BigRAMPlus card and my Amiga 4000 which seems to work fine otherwise could not even see it.  I am wondering if the power supply may be too weak to power the Zorro slots.  The thought of turning on my Amiga one day and having the power supply fry the motherboard give me the willies!
 
I have looked at the replacements I've seen online from a few years back but those appear to be generally out of stock. 

Perhaps a very clear set of ... understandable ... guidelines as to how to select one.  I can identify the necessary current levels, but how would I know if a PSU regulates voltages based on the 12V or 3.3V usage and not the 5V?  Or has a fan that does not operate continuously? Or simply will not fit?

Or is there an Amiga vendor somewhere who maintains a stock of suitable replacements for the A4000, etc?

A sticky on this subject would be nice.

Thanks

For my ever expanding fleet of A4000D setups. I now use Corsair SF450 or SF600 PSUs with a Amiga A4000 Power converter cable.

Can be hard to get the Corsair models I have described. But can still be found on Ebay. You can also get a SF PSU holder via 3D Print or via a Metal Frame off a seller on Amibay.

As for A3000 PSUs. Chris Edwards did a video on YouTube about a replacement he bought, but had to do some soldering for it.

These are some of the PSUs I have come across in the context of Amiga power supply replacement. 

These appear to have been used successfully:

Corsair SF (SF450/600/750?)
Mean Well RPT-160B
Be Quiet! SFX-L Power 500W PSU

I would like confirmation on the suitability (or unsuitability) of these:

Seasonic GX (550)
EVGA SuperNOVA GM (750)
Sharkoon SilentStorm SFX Gold 500W
Chieftec CSN (450C/550C)
Coolermaster (V550/650/750/850 SFX Gold)

And of course any that could be added to the list.

IMHO I would stick to what is good. For the ones you have listed, I would seriously do some research before considering buying them. Especially on Reliability.
Do not skimp on price and quality 😉
