Schematic in PDF form for Chieftec power supplies, with the name pointing to the HPC-750 and CFT-850G-DF models and a revision-style suffix 189_0_0. At only 140 KB it is likely a compact circuit drawing rather than a full service manual. PSU technicians use such a diagram to follow the primary and secondary sides, the PFC stage, standby supply and protection circuitry when diagnosing a dead or tripping unit. Compare the PCB markings of the actual unit before trusting component values, and discharge bulk capacitors before probing.
