How do you reduce voltage from 12 volt to 9 volt?
(1/3) > >>
Hoagie_one:
I have a set of powered PC speakers, but do not have the power brick.  It says it requires 9v AC in, and since I'm just going to use the amp inside to power my original cab speakers, I want to just power it directly from my PC's internal power.  What do I have to solder in to reduce the voltage?

Also, does internal PC power run AC or DC?

Thanks

Pc power supplies serve out DC voltages.  It would probably be easier to go to RadioShack and pick up a Walwart (plug that fits yours which is rated 9v) and then use a SmartStrip power supply.  The smart strip will turn on and off with the power of your computer.  This setup will prove to be the easiest, and probably only set you back about 30$ total.

Actually, you don't want to run it from your PC power supply.  It will place additional work on the PS and eventually fail because of that.

Whats funny is the price for a new AC adapter is generally more than a whole new set of generic PC speakers.

Any other alternatives?
