Applications

200W ATX power supplies like this Sunlan unit were standard equipment in desktop computers and workstations throughout the 1990s and 2000s, particularly in systems built around budget to mid-range component sets. These supplies provide the regulated 3.3V, 5V, and 12V rails required by computer motherboards, hard drives, optical drives, and expansion cards. While modern systems have largely moved to higher-capacity units (300W+), replacement or legacy system restoration projects, retro computing builds, and systems running older hardware still rely on appropriately-sized supplies like this 200W unit. Sunlan power supplies were known for compatibility across various OEM and white-label systems of that era.
