Dual X-capacitors (differential mode filtering), Y-capacitors tied to chassis ground (common mode filtering), two toroidal common-mode chokes, and a Metal Oxide Varistor (MOV) for surge suppression.

Generic Chinese power supplies rarely include a schematic in the user manual. Here are the most effective methods to acquire the exact : D10-240p1a Schematic

At the heart of the schematic is the (often an IC like the TL494 or similar proprietary chips). Unlike old-school transformers that stayed "on" constantly, this controller flips a set of MOSFETs (transistors) on and off thousands of times per second.

The green "PWR ON" wire on a standard ATX supply is not present on this unit's main connector. The power-on signal is implemented on a separate connector (P2).
