HP L08261-004 180W Desktop Power Supply Unit — OEM Replacement for HP Desktops

The matched 180W supply for HP desktops that shipped with L08261-004.

The HP L08261-004 is a 180W internal power supply for select HP desktop computers. It uses HP-specific connectors and mounting and accepts 100–240V AC input. It suits home users, offices and repair shops replacing the original unit in HP desktops that list this spare part number.

Why Newer HP Desktops Need an HP Supply

Many recent HP desktops use proprietary motherboard power connectors rather than the standard 24-pin ATX plug. A retail ATX supply cannot connect without adapters, and the case often will not accept it.

The L08261-004 is the HP spare part made for these systems. It plugs directly into the HP motherboard, fits the original mounting and supplies the correct power for the platform.

Right-Sized for Efficient Desktops

A 180W rating matches the low power draw of modern HP desktops built around efficient Intel and AMD processors. Right-sizing helps the supply run in an efficient range.

Direct OEM Replacement

Mounting points, cable lengths and connectors match the original unit, so installation is quick and straightforward.

Setup Instructions

How to Replace the HP L08261-004

1. Shut down the HP desktop, unplug the AC cord and press the power button for a few seconds to drain residual power.
2. Open the side panel, photograph the cable routing, then disconnect the power cables from the motherboard, drives and any graphics card.
3. Remove the mounting screws or release latch, take out the old unit and install the replacement in the same position.
4. Reconnect every cable, close the case, plug in the AC cord and power on to confirm the system boots and the fan spins.
