Replacement ATX power supply for U20 systems

This 400 W ATX unit is built as a direct replacement for the U20 300-1950-01 chassis. It is intended for owners who need a tested, working spare or upgrade for that specific platform. Builders using other cases or form factors will not be able to use this supply.

Tested unit with standard ATX thermals

Each unit is verified working before it ships, so it delivers stable 400 W output with normal ATX cooling and noise levels. Power draw follows the load you place on it, and no special thermal management is required beyond typical case airflow.
