SUN U20 Workstation Power Supply

This 400W ATX unit is built as a direct replacement for the Sun U20, Ultra 20 and M2 workstation platforms. It uses the specific part numbers 300-1794300-1950 and API4PC01 to match the original equipment specifications. The power supply is supplied new and has been tested working before shipment. It targets IT teams maintaining these legacy systems or owners restoring original hardware.

400W Capacity for Legacy Workloads

The 400W rating supports the processors, memory and storage configurations originally shipped in these workstations. Headroom is limited to the factory design envelope, so adding high-power graphics cards or large drive arrays will exceed the available output. Builders needing more power for modern upgrades should look for a higher-wattage unit with the correct proprietary connectors.
