Mounted to the secondary heatsink to smooth out the +12V rails.

The HP/Compaq PS-4241-9HA is a 240W 80 PLUS certified power supply used in SFF desktops like the Elite 8000/8200 and Pro 6000/6200 series, featuring 90.51% peak efficiency

When you open the datasheet for the PS42419HA, the “Top Schematic” usually reveals six distinct functional blocks. Let’s break them down.

If you need help identifying a specific component on your board, please tell me of the PCB you are working on or describe any part markings / markings printed on the silkscreen (e.g., IC1 , R50 , D12 ). Share public link

Based on forensic repair analyses of the PS-4241-9HA, several components are prone to failure: Component Component Type Component Role Typical Symptom (IC) Standby Voltage IC Total failure, no 5V/12V standby MBR3100H (Diode) Schottky Diode (Output) Shorted standby, PSU protection active CMAINcap C sub cap M cap A cap I cap N end-sub (Capacitor) High voltage smoothing PSU hums, won't turn on Fuse (Primary) Protection Totally dead, caused by shorted FET The Standby Problem (Missing 12VSB)

: Regulates power across specific 12V rails. Unlike standard ATX supplies, this model often uses proprietary HP 6-pin and 4-pin connectors rather than the traditional 24-pin ATX header. Role in Enterprise Computing

Shorted primary switches will trigger an immediate shutdown or cause the main line fuse to shatter. Mounted to the secondary heatsink to smooth out

) feeding the main DC voltage to the drain pin of the standby chip. If the IC shorts out, this resistor blows open to act as a secondary safety mechanism.

The “schematic top” refers to the high-level block diagram and primary power flow, as opposed to the detailed transistor-level layout. It focuses on the power stage, bootstrap circuitry, control logic pins, and protection zones.

If troubleshooting is outside your skill set or the damage is extensive, replacing the unit is the most reliable solution. Ensure the replacement is a for your system.

: Look for the component on the manufacturer's website. Most electronics manufacturers provide datasheets, application notes, and sometimes reference designs or schematics for their products.

The top schematic always places these high-current paths wide and without switching noise injection points. Decoupling capacitors (typically 10µF to 100µF electrolytic + 0.1µF ceramic) must be placed physically close to these pins.
