This power supply is loafing at less than 4 amps, and there is only one
plug in the wall! On a 35 amp supply, you could power about 150+ modems.
That works out to less than $1 per modem as the supplies are about $150.
The down side is, if the power supply dies, so do all your modems. I
don't think that is to likely though. If it does die, you will hear about
it real soon!
By the way, don't worry if your wall transformer puts out AC. Give the
modem DC anyway, as the first thing the modem does is pass it through a
rectifier, and change it to DC anyway. The modems run cooler too if you
give them just enough voltage to operate. You might need to experiment a
little to find out how much is needed.
