Lacks the wattage and connectors for modern GPUs.

The is a 240-watt power supply unit (PSU) primarily used in HP small form factor (SFF) desktops, such as the HP Compaq 6000 Pro and Elite 8000/8200 series . While a full, official manufacturer schematic is rarely released to the public, technical analysis and repair documentation provide a clear "top-down" view of its internal architecture and common failure points. HP PS-4241-9HA Core Specifications Max Output Power : 240 Watts. The auxiliary section operates independently from the main

While drawn as simple triangles on the schematic, these diodes carry the full motor current during PWM off-time. Underspecifying them (even if the IGBTs are larger) can lead to thermal runaway. The schematic top implies these diodes are matched to the IGBT—but verify the datasheet ratings.

Plug the PSU into the wall. Shorting the green to black signals the PSU to turn on.

The PS-4241-9HA is a robust unit but is susceptible to age-related component failure, specifically in the standby IC and secondary diodes. By focusing on the TNY279PG and the Schottky rectifiers on the schematic top , many of these units can be effectively repaired rather than replaced.

Lowers the high-voltage DC to continuous standby voltages. Bridge Rectifier: Converts AC to DC

: Integrated gate drivers for the high-side and low-side IGBTs, which allow the module to be driven directly by a microcontroller.
