I am looking for info on PC power upplies so I can modify them. Basically I
woant to modify the +/_ 12 volt section to produce other voltages and
currents. Some supplies would need to be modified to supply up to 50 volts
at 4 amps and others would need to be a bipolar supply up to +/_ 20 VDC at a
max current of 8 amps. If this info is already available that would be great
, otherwise good schematics of the power supplies would be useful so I can
figure out how to mod them myself.

Both examples of mods and at least one good schematic are available on the
net. Just google.

A few months ago Elektor magazine published a project to convert a PC PSU to
supply a single 12V rail for LV halogen lighting, that might contain some
useful background info.
