Hi everyone,
I'm looking to do something to get -5v from a modern ATX PC power supply. Older computers used this -5v for some things (certain expansion card) but the -5v line was eventually phased out of the ATX spec. This is a problem for people adapting modern power supplies to use in older PCs.
What could provide this, using the +12, +5 or even +3.3v rails? There is a -12v rail but I dunno if sharing that would be a good idea (it's generally only around 800ma) ?
Ideally to get 300-500 amps output for the -5v.
I don't really know what to look for in terms of a pre-built circuit or what I'd need to get myself to make something to do this. Any suggestions would be great!
Thanks!
