The power supply to any computer speaker set with a sub woofer (of the right voltage) should have exactly enough kick for you. They range anywhere from 700ma to < 1.5a depending on the size of your sub... So they will definately be able to power the cathodes. You don't even need to cut wires if you don't want to... using a little electrical tape I was able to hook the load (in my case not the KOP lights) up to the existing power jack on the cord with no risk of fire/failure.


As a side note: I was actually doing this to power a car amplifier/stereo system with 12" subs in my room. I used the power supply from a $40 pair of computer speakers to hook directly into the amp power in, and since those subs drew a heck-of-a-lot more current than the cathodes, I don't foresee any problem at all. I don't know if there is some difference which I am overlooking, but there shouldn't be.
