The is a 240W 80 PLUS-compliant power supply unit (PSU) primarily found in HP Hewlett Packard small form factor (SFF) desktop computers. This switching power supply is known for its high efficiency (over 90% at typical loads) and custom compact layout. Technical Specifications and Architecture Rated Power: 240 Watts. Input Range: 100–240V AC, 50–60Hz, 4A. Output Rails: Main +12V (cumulative). 12VSB (Standby Voltage).

Why? To reduce idle power draw for the Japanese Energy Conservation Law, which went into effect in April 1999. The board was dated October 1998. They'd erased a physical component to comply with a law that didn't yet exist, leaving only a ghost on the schematic.
