You need an AC-DC power supply. You can also run it off the 12v from an ATX power supply as well. Another option is a car battery, but some people are leery of having one in the house.
I have an opus 120W power supply and was wondering if there was a power brick to power this in the house.
great i have 2 or 3 power supplies and was wondering if i could convert those
use anything from 12-24 volts ... i use my laptop power supply when i want to test it in the house and just find some random 12volt power supply to use for the remote trigger.
