Power Supply + Cold Cathode Question...

[Futher]

I am using a 350 watt PSU and everything is getting power just fine. I decided I wanted to hook up 3 cold cathodes, so I upgraded to a 431 watt PSU. Think that will be enough?

They might demand 5 watts each, so I bet the 350 would have been fine.

nah, I tried 1 cathode and there wasn't enough power.... I am using this PSU to the max =) As long as 431 is enough, that's all I need... thanks
