    I'm wanting to add a couple of additional voltages to an old PC power supply that I have. It currently has leads for 3.3, 5 and 12 volts. Wanting to add 6v and 9v. Can someone point me to info on the components needed to add these voltages? Thanks!

    It's not really easy to do this.

    You may be best having an external 6 and 9 volt regulators that reduce the 12V rail.

    How much power (watts) or current (amps) do you require on these additional rails?

    Thanks Steve. My objective is to build a DC power supply that I can use to power a variety of "simple" IC circuits. 100 watts of 9 or 6 volt power would work great. One amp would do as well?
