24 volts off an ATX power supply? - 04/19/07 06:27 PM

I am considering building a desktop system based around a powerbook logic board, I would rather not use the power adapter from the laptop to power the board. The board expects 24 volts, is there any way to get this off an ATX supply? Check this out: http://www.afrotechmods.com/fanmod.htm

Closest I can think is to use or change the 28V feed on the PSUs from ADC PowerMacs. These usually run closer to 24V anyway....

You can use a standard ATX power supply but you would need a DC - DC power inverter. AllElectronics.com has one for sale for 5 bucks and it can turn 5 volts into 28volts and it is selective so you can use it for 24 volts.
