It's not turning on!! Is it power supply (only)?

[sim085]

Hello,

My A500+ has been packed in a box for the last two years or so. I pulled it out yesterday and today I tried to turn it on ... I heard a noise from the power supply (can't really explain the noise, but not a loud bang, more like sparkling water) and nothing happened. When I smell the power supply I smell something burnt, but not a big smell.

My question are; did I damage my A500+? and what are my options?

You're only option right now it to try another power supply!

Is it possible to turn a PC power supply to an Amiga power supply?

Thanks for everyone for the replies. I'll see how to convert an ATX power supply to an Amiga PSU. I can conform it is the PSU since there are clear signs of burnt.

Does anyone know from where I can get the schematics of the A500 PSU so I see what exactly went caput? Also is there anyone who managed to fix one of these PSUs?

Depends on what went pop... if it was just a capacitor, then just change it! Very cheap and easy.

I attached a photo ... I marked the burnt area with a red oval.

Amigakit sell adaptors for PC PSUs by the way....

I have several spare ATX power supplies and I am reading the following as suggested in this thead;

Am I right ... the ATX motherboard connector is connected to nothing? (when green PS-ON is connected to ground).

I did the ATX Power Supply hack and my A500+ is up an running again .. just loaded workbench from disk just like the old times!! It is a pitty re: Amiga Power Supply. Would like to see if it can be fixed. I really throw nothing Amiga these days. Thanks to everyone for all the help.

I am going to bring this up just to ask a question; could the Amiga power supply have gone because of the high humidity where it was stored? In my country we have very high humidity in winter. Before I stored it the Amiga power supply was fine; then it went nuts with a single switch on… yesterday a PC monitor I had (stored in the same place) also when nuts… Therefore I was thinking maybe I should switch the A500+ in summer
