Power supply Dell KMJP5 200W for Small Form Factor PCs

Dell KMJP5 200W internal power supply is designed for Small Form Factor (SFF) desktop PCs. It delivers a compact, OEM-compatible source of DC power for SFF systems, supplying the motherboard, CPU, storage drives and low-power expansion devices. The unit is intended as a direct replacement or upgrade for compatible Dell SFF models where a space-saving 200W module is required.

Advantages

The supply offers a compact form factor that fits into SFF chassis while providing stable 200W output for typical office and home computing loads. Built to OEM mechanical and electrical specifications, it supports reliable startup and steady voltage delivery to critical components. Its internal configuration minimizes cable clutter and maintains compatibility with standard SFF connectors, helping simplify installation and reduce the need for additional adapters.

Suitable for

• Repair or replacement of internal PSUs in Small Form Factor Dell desktops
• Upgrading existing SFF systems that require a 200W power budget
• Service centers or technicians maintaining compact business and home PCs
• Systems with low- to moderate-power CPUs, a single storage drive and basic peripherals

Key specifications

• Output power: 200 watts
• Form factor: internal, Small Form Factor (SFF)
• Output voltages: standard desktop supply rails for motherboard and peripherals
• Cooling: internal fan or passive airflow compatible with SFF chassis
• Connectors: SFF-compatible power connectors for motherboard, CPU and storage devices
• Compliance: built to OEM electrical and mechanical dimensions for compatible Dell SFF models

How to use

Power down the computer, disconnect external power and open the SFF chassis following the manufacturer's service instructions. Remove the existing power supply by disconnecting its cables from the motherboard and drives, then uninstall any mounting screws or retention mechanisms. Install the replacement KMJP5 unit in the same orientation, secure it with the original mounts, and reconnect the power connectors to the motherboard, CPU and storage devices. Close the chassis, reconnect external power and power on the system to verify normal operation and stable voltages.

Recommendations

Use this 200W supply in systems whose total component power draw does not exceed the unit’s rated output, and ensure compatibility with the target SFF chassis and connector types before installation. If the system will run high-power CPUs, multiple drives, or discrete graphics, verify required power headroom or consider a higher-capacity solution.
