Built for Sun U20 and Ultra20 M2

This 400 W ATX power supply is a direct replacement for Sun U20 and Ultra20 M2 workstations. It matches the original API4PC01, 300-1950-01 and 300-1794-03 part numbers so the system powers on without adapter cables or pin-out changes. Buyers who need a different form factor or higher wattage for another platform will not be served by this unit.

Fits the original chassis and wiring

The unit slides into the factory power-supply bay and connects to the existing motherboard and drive connectors. Its ATX layout means standard 24-pin, CPU and peripheral cables are already routed for the Sun chassis, freeing the builder from sourcing custom harnesses or modifying the case. Systems that require redundant or hot-swap modules cannot use this single supply.

Sustained efficiency and quiet operation

80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat during long work sessions. Resonant LLC topology with DC-to-DC conversion delivers stable voltages under continuous demand while suppressing coil whine. The Zero RPM fan mode keeps the cooling fan off at low and medium loads, so the workstation stays near-silent during extended idle or light compute periods.
