    A way to tell if your power source is marginal, is to watch the opening screen at boot up.  If there is an extra rainbow block in the upper right during the startup messages, it is a signal that the power level is low.  If this is the case, any devices that are added before power on can bring the level below what is needed to provide proper switching and the power circuit will not come out of reset. A 2A is really necessary, even though the newer B2, B+ and A+ have all improved their power requirements.
