Power supply Dell D13 300W for small form factor (SFF) systems

The Dell D13 300W internal power supply is designed for small form factor (SFF) Dell systems. It provides a compact and direct replacement solution to restore stable power delivery for supported SFF chassis and motherboards. Built to fit constrained internal layouts, the unit supplies up to 300 watts to system components and supports typical SFF desktop configurations used in office and workstation environments.

Advantages

The compact dimensions and standardized connector layout make the power supply easy to install in compatible Dell SFF cases without extensive modification. Its rated 300W output ensures adequate power for common CPU, memory and storage combinations found in small desktops. The internal design includes necessary protections to maintain steady voltage under normal operating loads, helping to reduce unexpected shutdowns and component stress.

Suitable for

• Replacing a failed or underperforming power supply in Dell small form factor desktops
• Repairing office PCs and workstations that use the compatible SFF chassis
• System refurbishing where compact, reliable power delivery is required

Key specifications

• Output power: 300 watts
• Form factor: internal, small form factor (SFF) compatible
• Cooling: built-in fan for thermal management
• Connectors: main motherboard power and standard peripheral connectors for SFF systems
• Designed for use in office and workstation small desktop configurations

How to use

Before installation, disconnect the system from mains power and ground yourself to avoid electrostatic discharge. Open the SFF chassis according to the manufacturer's service instructions, remove the existing power supply if present, and note the orientation and connector locations. Fit the D13 300W unit into the original mounting points, secure it, and connect the motherboard and peripheral power leads to the corresponding sockets. Close the chassis and reconnect mains power, then power on the system to verify normal operation and stable voltages.

Recommendations

Use this power supply only in compatible Dell small form factor systems and follow the chassis service guide for safe installation. Verify that total system power requirements do not exceed 300W under peak load and ensure adequate ventilation in the case to maintain cooling performance.
