Almost every circuit that you can find today in any electronics appliance or gadget features or uses the +5V supply where the circuits that depend on them vary depending upon the need to see what requirements the whole circuit may need in terms of load limit.
A +5V power supply always and should never fail what is needed of it by the circuit that it supplies and this has something to do with a few common troubles that you may encounter in case that you find this +5V power supply way beyond what it should supply the circuit that you have in terms of load current and load voltage. Whenever either of this load limits exceed or or go way below its supposed value, there will be an equivalent failure in your circuit and most experiences would include power failure or intermittent power failure of any electronic appliance or circuit.
In an amusement machine, however, it is very important that this +5V power supply should be at its tolerable level because it is what it important of it. This must and should never fail what is required of it. This would result to such bigger problems in the end and in some cases, even at the start up or power up of any amusement machine because such amusement machines use PC-type circuit boards.
