If your device blows one power supply that’s random enough, but for it to blow a replaced power supply leads me to believe that your home wiring could be causing the issue. If you have a bad ground on the circuit it’s plugged into or if something is causing power surges that would result in the power supply blowing a fuse which exists to ensure that a power surge can’t fry your entire system. Usually with any device that uses power through the wall and has been manufactured within the past 20 years there is always a safety fuse that’s sole purpose is to ensure that the 120 volts from the wall doesn’t destroy the device in the even of a power surge. The surge happens and as the electricity increases into the system it would destroy the sensitive components on the device which rely on the power source to take the 120v and scale it down to a fraction of that in order to provide the power level needed for the device to operate (usually a few watts). If the full 120v surges beyond the power supply there’s a fuse which is designed to handle a set amount of current and anything more will result in the fuse blowing which leads to a new fuse being required (most likely in the form of a new power supply unit) which does suck but if that fuse wasn’t in place then the surge would fry the chips on the logic board and render the device unfixable. I would investigate your circuit and see if that’s you issue.

Usually with any device that uses power through the wall theres a safety fuse to ensure that the 120 volts from the wall doesn’t destroy the device in the event of a power surge. If a surge happens it will cause the electricity to move into the system and without a fuse it would destroy the sensitive components on the device.

120 volts is a substantial amount of electricity and its far beyond what any household product needs (except a dryer and some stoves). Thats how you’re able to connect multiple devices with a power strip through one plug. Electronic devices use a power inverter somewhere in the device which takes the 120v and scales it down to a fraction of that in order to provide the power level needed for the device to operate (usually a few watts).

If the full 120v surges beyond the power supply capability, there’s a fuse which is designed to handle a set amount of current and anything more will result in the fuse blowing which leads to a new fuse being required (most likely in the form of a new power supply unit) which does suck but if that fuse wasn’t in place then the surge would fry the chips on the logic board and render the device unfixable.
