ATX Power Supply Pinout

Published:2013/3/22 3:31:00 Author:Ecco | Keyword: ATX Power Supply | From:SeekIC

The ATX power supply generates three main voltage outputs that are: +3.3 V ; +5 V ; and +12 V. Low-power −12 V and +5 VSB (standby) supplies are also generated by this power supply. The −5 V output was originally needed since it was supplied on the ISA bus, however it became obsolete with the removal of the ISA bus in modern day PCs and has been removed in later versions of the standard ATX power supply.
