7.2. LEDs and Indicators
Indicators and LEDs indicate only presence of voltage on certain signal, but not necessarily a correct shape and level
of the voltage. This is important especially for power supplies – power good signal would provide more accurate
indication, but it is not possible to provide this for all signals (for example ATX power signals share one power good).
