You need an ADC to DVI adapter that also supplies Power. The ADC to DVI only (i.e. cheap) adapter will not work as that is for hooking a standard DVI monitor to a Mac Pro with ADC outputs.
At this point, it is cheaper just to buy a new monitor and will be much bigger unless you can find a used ADC to DVI adapter somewhere. Further then you will need a DVI to Mini Displayport Adapter as well, but those can be found for fairly reasonable prices (like $10).
