3VCC
To ensure that VCC does not fall faster than VSB in various ATX Power Supplies, the W83627DHG-
P adds the option of “user define mode” for the pre-defined state before AC power failure. BIOS can
set the pre-defined state for the system to be “On” or “Off”. According to this setting, the system
chooses the state after the AC power recovery.
