Compatible Dell OptiPlex SFF systems

This 240 watt power supply is built for Dell OptiPlex 390, 790, 960, 990, 3010, 7010 and 9010 small form factor desktops. It replaces part numbers 3WN11, 03WN11 and CN-03WN11. The unit is new and matches the original form factor for direct installation.

240 watt maximum output

The supply delivers up to 240 watts of continuous power for the supported OptiPlex platforms. Input voltage ranges from 100 to 240 volts AC at 4.0 amps, 50 to 60 hertz. This rating determines whether the unit can sustain the system load without shutdown.

Steady 240 watt delivery under load

Designed for sustained operation at the rated 240 watt maximum rather than short peak bursts. The wide input range maintains stable output during prolonged workloads. Builders needing higher continuous power for expanded configurations should verify total system draw before selecting this unit.
