Power Supplys Attempt (2)

[dzorde]

Depending on what you want to run with the PC, you'll only need 5V.  The
other voltages are for the floppy and hard drive.  But if you were to use a
flash drive instead of a floppy and hard drive you could get away with only
a 5V supply.

By the way there was a big discussion on this subject a few months back,
check the archives and you should find lots of useful info.
