If you decide to try and repair your power supply, please replace the cover
before you switch it on.
Most SMPSs generate a high voltage, about 300V DC on the heatsinks, which is
unhealthy to touch.
We fried a supply here once during testing, and what blew up were
- rectifiers
- part of the copper track
- fuses
The rectifiers are a special type, so don't just substitute anything.
Also many SMPSs won't work without a load of some sort, so you might need to
plug in a light bulb as a load (safer than plugging in a computer), eg 12V
bulb on the 12V outlet, or a 6V / 5V bulb on the 5V outlet.
You need to verify that all outlets are working before you plug it in the
computer.
Or you can just chuck it and put in another one from a junked computer.
Depends on whether you can stand the smell.
