The PS-4241-9HA is a 240W Power Supply Unit (PSU) manufactured by HP, specifically designed for Small Form Factor (SFF) desktop computers. It is a common replacement part for business-class machines like the HP Elite 8000, 8100, and 8200 series. Technical Overview

This power supply is known for its high efficiency and specialized "proprietary" connector layout, which differs from standard consumer ATX power supplies. Form Factor: Proprietary SFF (Small Form Factor). Maximum Power: 240 Watts.

Efficiency: 80 PLUS Bronze or Silver certified, with a typical efficiency of 90.51% at 50% load. Connectors: (1) 6-Pin Main Power Connector. (1) 4-Pin ATX +12V Power Connector. (1) 6-Pin Auxiliary P2 Connector. Top View and Schematic Details

While a full internal component-level schematic is rarely released by HP to the public, the "top" orientation usually refers to the PWB (Printed Wiring Board) layout used for troubleshooting.

Input Section: Located near the AC socket, containing the transient filtering (X/Y capacitors and common mode chokes) and the bridge rectifier.

PFC Stage: Features a large high-voltage electrolytic capacitor and an active Power Factor Correction inductor.

Secondary Side: Contains the DC-to-DC conversion stages for the +12V rails. Note that this unit primarily outputs +12V, as modern HP business desktops often use 12V-only motherboards with localized voltage regulation for 5V and 3.3V. Compatibility and Use Cases

This PSU is a "critical component" for maintaining the operation of legacy enterprise systems. It is not suitable for:

High-End Gaming: Lacks the wattage and connectors for modern GPUs.

Standard ATX Cases: The mounting holes and size are unique to HP SFF chassis. HP Inc Ps42419ha 9244 | PDF | Power Supply - Scribd ps42419ha schematic top

The PS-4241-9HA is a 240W Power Supply Unit (PSU) manufactured by HP for use in their small form factor (SFF) desktop computers. While a complete proprietary schematic is typically not released to the public by HP, the unit's design and technical specifications provide a clear roadmap of its internal architecture and role within enterprise computing. Technical Architecture and Efficiency

The PS-4241-9HA is engineered with a focus on high efficiency and thermal management within tight spaces. According to its 80 PLUS Verification Report , the unit achieved an average efficiency of 88.83% and a peak efficiency of 90.51% at typical (50%) load.

The internal schematic "top" view follows a standard high-efficiency switching layout:

Input Stage: Features transient filtering and an active Power Factor Correction (PFC) circuit to handle 100-240V AC inputs while maintaining a power factor close to unity (0.99 at full load).

Switching Stage: Uses high-frequency transformers to step down voltage, governed by a Pulse Width Modulation (PWM) controller.

Output Stage: Regulates power across specific 12V rails. Unlike standard ATX supplies, this model often uses proprietary HP 6-pin and 4-pin connectors rather than the traditional 24-pin ATX header. Role in Enterprise Computing

This PSU is primarily found in HP Compaq Pro 6000 and Elite 8000 series SFF desktops. Its design reflects a shift toward energy-conscious office hardware, where compact size and low heat generation are critical. The unit's reliability is evidenced by its widespread use in "Grade A" refurbished markets, where it is frequently sold as a drop-in replacement for aged enterprise fleets.

Technicians often encounter specific component failures in this model rather than replacing the whole unit: 

Here is the information regarding this specific part and how to find its documentation:

Before dissecting the schematic, let’s establish the context. The PS42419HA is typically a hybrid integrated circuit (Hybrid IC) or a Smart Power Module (SPM). While branding varies (common in Mitsubishi, Fuji, or Sanyo families), modules with this naming convention generally feature:

The “schematic top” refers to the high-level block diagram and primary power flow, as opposed to the detailed transistor-level layout. It focuses on the power stage, bootstrap circuitry, control logic pins, and protection zones.

If you have the physical component and are trying to solder or trace connections:

While drawn as simple triangles on the schematic, these diodes carry the full motor current during PWM off-time. Underspecifying them (even if the IGBTs are larger) can lead to thermal runaway. The schematic top implies these diodes are matched to the IGBT—but verify the datasheet ratings.
