Another ATX addition was the +5 V SB (standby) rail for providing a small amount of standby power, even when the computer was nominally "off". When a computer is in ACPI S3 sleep mode, only +5 V SB rail is used. There are two basic differences between AT and ATX power supplies: the connectors that provide power to the motherboard, and the soft ...
