Hi Guys,
I have a Dell NPS 330 GB B power supply that I want to convert into a DC power supply unit. Could some one let me know what wires go where? I'm going to use this to power a Lipo battery charger. My question is probably pretty vague but I don't know where to start first.

Well guys I've done some research and can be more specific about what I need to know. O know that yellow wires are +12 volts, black is ground, red is +5, and orange is +3. I need to know which wire by color is the load wire to make the power supply come on and which wire by color is the wire to put an inline SPST switch in to turn the unit on.

most atx power supplies can be turned on by jumping the green wire with one of the black ground wires. older dell power supplies used different pinout and colors. http://pinouts.ru/Power/dell_atxpower_pinout.shtml
