If you need a specific schematic, let me know the (sometimes printed in white letters on the PCB, e.g., "YX-360W-12") or if it has a socketed controller chip . I can try to help you locate a specific version.
This table summarizes the primary electrical and physical characteristics of the power supply, providing a clear benchmark for its performance and capabilities.

Understanding the is essential for technicians, engineers, and hobbyists looking to repair, reverse-engineer, or troubleshoot these units. This article breaks down the architecture of this popular, often generic, 360W power supply. 1. Overview of the S-360-12 SMPS Design
rated) in a voltage-doubler or full-bridge configuration depending on the input switch position. C. Half-Bridge Switching Stage (The "Switching" Core)
Popular controller ICs for this design include models like the (a classic) or the 8-pin 2842 series. The controller generates a precise square wave signal that drives the gate of the MOSFET. By varying the duty cycle (the ratio of "on" time to "off" time) of this signal, the controller adjusts the amount of power being transferred to the output. This dynamic adjustment is what allows the power supply to maintain a constant 12V output even as the load changes dramatically. | Reference | Part Type | Value /
