Applications

AT-form-factor power supplies were the standard for IBM PC/XT and AT-compatible desktop computers through the early-to-mid 1990s, before the ATX standard replaced them. The SA145-3437 was used in Dell AT-based desktop systems of that era. Today these units are sought for legacy system restoration, vintage PC repair, and replacement of failed AT PSUs in older industrial or embedded systems still running AT-chassis hardware.
