Schematic in PDF form for the Dell OptiPlex 5050 MFF-AF board, the micro form factor variant, about 3.10 MB. A related boardview identifies the board maker as Pegatron. With the circuit diagram a technician can follow the power sequence from the DC input through the main regulators, check standby rails and inspect the signal paths of the PCH, memory and front-panel connectors. It works well alongside the matching boardview. Make sure the unit really uses the MFF-AF board before trusting the values.
