Unlike standard ATX power supplies that use a 24-pin connector, the D10-240P1A uses a specialized HP architecture. Connector Type Typical Usage Main Power Direct motherboard power (primary 12V rails) Dedicated ATX +12V power for the processor 6-Pin (Slim/Flat) Special motherboard or peripheral signaling Internal Circuit Blocks (Architectural Schematic)
to increase its 12V output to 14V, repurposing it as a high-current charger for 12V lead-acid batteries or for powering ham radios. D10-240p1a Schematic
