I have an old PSU I was thinking about using. I don't know its actual maximum output specs, it is just a PCB with no marked specs, but I could probably calculate a theoretical max based on values of the output rectifier diodes. I know in its original purpose, the +12V rail only saw around 550mA and 1A peak.
I only have a very rudimentary understanding of how SMPS work, so this may be a rather silly thing to ask: Would upgrading the input rectifier, switching transistor, and output rectifiers allow the PSU to supply more than its rated current before blowing up? I haven't checked my desired load with an ammeter, but I'd guess maybe 1.25A average and 3A peak.
