The statement "the power supply must be toasted" is a rather idiomatic way of saying, the power supply must have been destroyed by excess current.
is an embedded circuit or stand alone unit the function of which is to supply a stable voltage to a circuit or device that must be operated within certain power supply limits .
Generally yes. I recommend using a power supply tester- these are not expensive and readily available.
