The D10-240P1A (also referred to as the 611481-001 or 613762-001) is a 240W switching power supply unit (PSU) manufactured by Chicony and HP Inc. for use in HP Elite and Compaq Small Form Factor (SFF) desktop computers. Schematic and Circuit Overview While a complete internal circuit schematic for the D10-240P1A
is proprietary and rarely released by HP, its functional design is a standard switching mode power supply (SMPS). It operates by converting a high-voltage AC input into regulated low-voltage DC outputs through several stages:
Input Stage: Features an EMI filter and bridge rectifier to convert 100-240V AC to high-voltage DC.
Active PFC (Power Factor Correction): This unit is 80 PLUS Gold certified, meaning it includes a sophisticated PFC circuit to maximize efficiency and maintain a high power factor (typically 0.99 at 50% load).
Switching Stage: Uses high-frequency transistors (MOSFETs) and a transformer to step down the voltage.
Output Regulation: Provides specific rails for computer components. Unlike standard ATX power supplies, this unit uses a proprietary HP 6-pin main connector and a 4-pin CPU connector.

A Look Under the Hood
The schematic of a switching power supply like the D10-240P1A is essentially a roadmap of energy transformation. It begins with an EMI filter to block electrical noise from the AC line, followed by a primary stage where high-voltage capacitors and a switching transformer convert AC to DC with minimal energy loss. Key highlights of its schematic work include: Thermal Efficiency
: Because it resides in a cramped "Small Form Factor" case, the layout of heat sinks and the internal fan is vital for dissipating heat. Voltage Regulation
: The circuit utilizes a complex feedback loop—often involving an opto-isolator—to ensure that even under a heavy load, the 12V output remains rock-steady. Proprietary Pinouts
: The most "interesting" part of its schematic for hobbyists is the non-standard wiring, which often requires creative solutions or adapters for those looking to modify the unit for external projects, such as increasing the voltage for bench testing. Conclusion
The D10-240P1A schematic is more than a technical drawing; it is a blueprint for the "compact era" of enterprise computing.
