Product information

Description

Replacement 240W ATX internal power supply designed for HP DC7800 and DC7900 CMT desktop models. This unit provides stable 240-watt power delivery with standard ATX connectors to support motherboard, CPU, storage devices and peripherals in small-form HP business desktops. It restores reliable boot performance and maintains proper voltages under typical office and home workloads, ensuring compatible operation with the original system form factor and mounting points.

Advantages

The 240W ATX power supply delivers consistent output across standard ATX rails to preserve system stability and protect components from voltage fluctuations. Its internal form factor and connector layout match the original HP design to simplify replacement without additional modifications. The unit supports common desktop peripherals and storage configurations typical of DC7800 and DC7900 CMT systems, helping to extend the usable life of the desktop while avoiding the cost of a full system replacement.

Suitable for

  • Repairing HP DC7800 and DC7900 CMT desktops with faulty or failing power supplies
  • Restoring stable boot and operation in office workstations
  • Replacing a damaged internal PSU after power events or component failure
  • Maintaining existing HP small-form desktops in home or business environments

Key specifications

  • Output power: 240 watts total across ATX rails
  • Form factor: internal ATX power supply compatible with HP small-form CMT chassis
  • Connectors: standard ATX motherboard connector and peripheral power connectors compatible with original HP desktop wiring
  • Voltage regulation: regulated outputs for stable +12V, +5V and +3.3V rails
  • Cooling: internally mounted fan with chassis airflow support

How to use

Power off the desktop and disconnect all cables before beginning. Open the chassis following HP service instructions for DC7800/DC7900 CMT models, remove the existing power supply by disconnecting the motherboard and peripheral connectors, and detach mounting screws. Install the replacement 240W ATX unit in the same orientation, secure with the original screws, and reconnect all power connectors to the motherboard, drives and peripherals. Close the chassis, reconnect external cables and power on the system to verify stable boot and normal device operation.

Usage recommendations

Use the replacement power supply in environments with adequate ventilation and stable mains power. Verify connector seating and cable routing to avoid strain on connectors and ensure proper airflow. If the system exhibits instability after installation, re-check all connections and consider testing with a multimeter or replacement components to isolate issues not related to the PSU.
