Final answer:
ATX power supply soft power settings are configured in the system's BIOS or UEFI, where users can manage power-on behaviors and other power management features. It is advisable to consult the motherboard's manual for detailed guidance on configuration.
Step-by-step explanation:
The Advanced Technology Extended (ATX) power supplies feature soft power functionality, which unlike traditional power supplies, are controlled by the motherboard via software.
The important settings for ATX soft power are typically configured within the system's Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI). Within the BIOS or UEFI, users can configure settings such as the power-on behavior following a power failure, wake-on events, and other power management features. It's important to consult the motherboard's manual to understand the specific options available and how to navigate the BIOS or UEFI to modify these settings.
