D10-240p1a Schematic File
The schematic layout breaks down into three localized DC wiring output bundles instead of a standard 24-pin harness: Feeds the system board directly with , Ground, and system signaling links ( Pwr_OK , PS_ON ).
Blocks electromagnetic interference (EMI) from leaking back into the mains power line and protects the switching transistors downstream from sudden input voltage spikes. 2. Active Power Factor Correction (PFC) Circuit

The is typically a single-output, enclosed switching power supply rated for approximately 240 Watts. While specific branding varies (often found under generic Chinese industrial labels or as a replacement for proprietary systems), the "D10" series generally denotes a compact metal-cased unit with the following typical specifications:
Because this unit is purely 12-volt based (the motherboard converts it to lower voltages), some users modify these for other 12V applications: The schematic layout breaks down into three localized
: If the voltage spikes too high.

Before analyzing the inner circuitry, it is essential to understand the nominal operating boundaries certified by the manufacturer. According to 80 PLUS efficiency testing data , the unit operates with high power factor values and optimized thermal dissipation:
Unlike a standard 24-pin ATX power supply, the D10-240P1A features a proprietary set of harness connectors. Technicians troubleshooting a "no power" state must understand these pin assignments to map voltages accurately.
