Capacitor list for Amiga 500 PSU Model 312503-03
Since I did not found this list on the web, I am publishing it for future reference.
It is 4,5A PSU. These are original values, as I read them on the board. Code:
******************** 3300uF 10V 105C 3300uF 10V 105C 100uF 450V 85C 0,47uF 50V 105C 10uf 25V 105C 1uF 50V 105C 1000uF 10V 105C 220uF 16v 105C 220uF 16v 105C 470uF 25V 105C 2200uF 16V 105C ********************* |

Thank you for sharing this. I've just realised I have problems with the power connector and a break in the wire of 2 power supplies! Whilst I'm looking at repairing the connector, I may as well replace caps.
Interesting that all bar 1 are 105 degrees. Thinking of these unless they're available in the UK? https://www.ebay.co.uk/itm/NEW-high-....m46890.l49292 The other consideration is to replace the internals with another psu altogether e.g. Mean Well and wire it up instead of Amiga PSU if anyone tried this?

That is what I planned to do, putting Meanwell PSU in Original Amiga PSU case. Then I was told that Meanwell PSU-s (as PC ATX PSUs) do not regulate voltage by 5V rail, but by 12V rail, which is hardly used in classic Amiga systems (without 3.5" hdds, CDROMS etc).
In that way they do not comply with Commodore PSU standards. I do not know if that is a thing or not, but I decided to get quality replacement capacitors and recap my Amiga 500 and Amiga 600/1200 PSUs that I have at home. |

Well, at least that's the main sales argument for the icomp PSUs. ;-)

I have the same power supply, same model number, but different capacitor values. Probably an entirely different psu but with the same model number. It's probably a good idea to check the board before ordering caps
