Basically I’ve stumbled my way into a modding web page and what can I say, I’m in love. My question is about the power. I’ve seen lots of groovy things I want to do and came up with a couple of my own ideas, but don’t want to drain my system of power. How do I know a device or a Molex connector  can handle extra LEDs, neon lights, or what ever I should decide to add in  with out under powering it ? Any websites or advice would be greatly appreciated.
