I'm working on converting a few ATX Computer power supply units for powering my FT-857d. Because I've only been able to find one or two articles detail this conversion, I'd thought I'd take it upon my self to document the details of my project as I can along so as others may learn from my mistakes and more efficiently diagnose their own problems with this. Stay tuned, more details and pictures in about an hour or two! So far it's three psu's with the 5+v bus wired in series, at 20 amps. Changing soon.
