The most important difference between ATX and AT is that the ATX power supply itself does not completely cut off power when shutting down, but maintains a relatively weak current. At the same time, it uses this current to add a power management function called Stand-By. It allows the operating system to directly manage the power supply. Through this function, users can directly realize soft shutdown through the operating system, and can also realize networked power management. For example, when the computer is turned off, a signal can be sent to the modem of the computer through the network, and then the monitoring circuit will send out a +5V SB activation voltage unique to the ATX power supply to turn on the power to start the computer, thereby realizing remote boot.
