Applications

ATX power supplies of this class were used in desktop computers and workstations from the late 1990s through early 2000s. This unit is compatible with standard ATX motherboards and systems requiring the ATX 20-pin connector. The dual voltage input made it suitable for both North American (115V) and international (230V) installations. It is no longer in production and may be used for legacy system repair, replacement, or retro computing applications.
