A lot of power supply units have fans in them, normally when you power up you will hear the power supply unit fans turn on. Unless you fancy trying the power supply out of the working pc in the non working PC it's not going to be easy to tell which is faulty to be honest. One quick check would be to undo the casing of the PC that is not working and some motherboards have a power led on them. You could open the case and try listening to the power supply unit or look for a light on the motherboard. Odds are its the power supply but without trying a known functioning power supply in the non working PC you won't know for sure.
