Before applying power, place your multimeter in diode/resistance mode. Measure the main ATX power rails (+12V, +5V, +3.3V) relative to Ground. If any rail shows zero resistance, do not plug in the power supply. Use a DC lab bench power supply to inject low voltage (e.g., 1V) into the shorted rail and use a thermal camera to locate the overheating component. Documentation and BOM Based on the updated E93839

Modern schematics account for variant board iterations featuring unique front-panel pinouts, localized VRM (Voltage Regulator Module) designs, and eSATA/DisplayPort controller mappings. Key Technical Specifications we recommend: Before applying power
