Wire Color Codes at ATX power supply

Bundle wires of the same colors together. IMPORTANT: Make sure that the lone brown sense wire is bundled with the orange wire. If the brown wire is tied to 3.3V, the power supply will produce an output. The color code for the wires is: Red = +5V, Black = 0V, Yellow = +12V, Blue = -12V, Brown = Sense (tie to 3.3V), Orange = +3.3V, Purple = +5V Standby (not used), Gray = power is on, and Green = Turn DC on.
