Hi John.

I cant see myself peddling a F&P generator so I can check my email, but this is interresting. The PC powersupply has a pretty dynamic input voltage range, and simply switch off if the input voltage is too low. Watch the high voltage, from memory most powersupplies have two big caps in series rated at something like 330uF 200V, so you have a max input of 400V before things go Bang! ( and it will be a hell of a bang! Seen it happen ).

I've heard you can boost up the 12v output. The powersuppy regulates on the 5v output, so you need to trick it to think the 5v is low so it will up the output level. But thats all I can tell you.
