Product information

Description

The DELL 3WN11 240W Active PFC Non-Modular Silver power supply unit delivers a steady 240 watts of output for compatible desktop systems and small servers. Designed as a non-modular internal PSU, it integrates Active Power Factor Correction (PFC) to improve energy efficiency and reduce harmonic distortion. With a compact form factor and a lightweight build of approximately 0.3 kg, the unit is intended for system replacements or OEM integration in supported Dell OptiPlex models and similar chassis that accept this physical size and connector layout.

Advantages

This power supply provides a reliable 240 W continuous output with Active PFC to support stable voltage delivery under typical desktop and entry-level server loads. The non-modular design simplifies installation in systems that use fixed cabling, and the silver enclosure offers a neutral aesthetic that fits most internal layouts. Low weight and compact dimensions make it suitable for constrained internal spaces while maintaining standard safety and electrical characteristics expected from Dell components.

Suitable for

Replacement power supply for compatible Dell OptiPlex desktops
Entry-level workstations with a 240 W power requirement
Small office servers or network appliances with matching connectors and form factor
Systems requiring Active PFC for improved power quality

Key specifications

Total output power: 240 W
Power factor correction: Active PFC
Design type: Non-modular internal power supply
Color: Silver
Approximate weight: 0.3 kg

How to use

Before installation, verify compatibility with your desktop or server chassis and confirm that the connector layout matches the motherboard and peripheral power requirements. Power down the system, disconnect all external cables and ground yourself to prevent electrostatic discharge. Remove the existing PSU according to the chassis service manual, position the DELL 3WN11 unit in place, and secure it with the appropriate mounting screws. Connect the fixed cables to the motherboard, drives and other components, ensuring firm seating. Reconnect external cables, power on the system, and check for stable boot and correct voltage readings if available.

Usage recommendations

Use this PSU in systems with matching mechanical and electrical requirements; avoid overloading beyond the rated 240 W continuous output. Ensure adequate airflow inside the chassis and keep vents unobstructed. For safe operation, perform installation with the system powered off and consult service documentation for torque and mounting specifications. Regularly inspect cables and connectors for wear and replace the unit if you notice unusual noise, overheating, or voltage instability.
