Power supply HP Slim 150W EPS 3-pin model 9ZE28AV for HP systems

Replacement HP Slim power supply delivering 150 watts of continuous output in a compact form factor with an EPS 3-pin connector. This unit is designed to fit compatible HP desktops and small servers that require a slim internal power supply with EPS-style power delivery. The power supply provides stable DC output to support CPU, motherboard and basic peripheral power requirements for routine operation, repairs or upgrades where space and thermal constraints demand a low-profile unit.

Advantages

The slim 150W design reduces internal space usage while maintaining consistent voltage regulation for system stability. An EPS 3-pin connector provides a direct power interface for compatible HP motherboards, simplifying replacement and service procedures. The compact housing enables installation in small-form-factor chassis and helps maintain airflow patterns established by the original system design.

Suitable for

• Replacement in compatible HP slim desktops and small servers
• Field service and repair tasks requiring a direct-fit compact PSU
• Upgrades where a stable 150W supply is needed without increasing chassis size
• Spare-unit inventory for IT departments supporting HP systems

Key specifications

• Output power: 150 W continuous
• Connector type: EPS 3-pin power connector
• Form factor: slim/low-profile internal power supply
• Cooling: internal fan or passive cooling designed for the host chassis (dependent on system)
• Compatibility: designed for use with compatible HP systems requiring a slim EPS 3-pin PSU

How to use

Turn off and unplug the host system before replacing the power supply. Open the chassis following the manufacturer's service instructions to access the existing PSU. Disconnect all internal cables from the motherboard and peripherals, then remove mounting screws securing the old unit. Install the replacement slim power supply in the same orientation, secure with screws, and connect the EPS 3-pin connector and any other required power cables to the motherboard and components. Close the chassis, plug the system into mains power, and power on to verify normal operation and stable voltages.

Recommendations

Use this HP Slim 150W EPS 3-pin power supply only in systems specified by the manufacturer for slim form-factor EPS connectors; verify connector compatibility and required wattage before installation. For safety, follow anti-static precautions and the system service manual during replacement. If the system requires higher peak power for additional components, choose a supply with appropriate capacity.
