D10240p1a Schematic — Work

The HP D10-240P1A is a 240W proprietary Switching Power Supply (SMPS) commonly used in SFF desktop PCs like the HP Elite 8000 and 8200 series. It features active Power Factor Correction (PFC) and uses components like the UC3845 or TL494 PWM controllers for voltage regulation. Common failure points include short-circuited MOSFETs on the 12-volt rail and degraded primary capacitors, with replacement compatible with part numbers 611481-001 and 613762-001.
