: The PS-4241-9HA heavily utilizes the TNY279PN Power Integrations IC (an energy-efficient off-line switcher).
: 80 PLUS certified, with a typical efficiency of ~90.51% at 50% load Input Voltage : 100–240 Volts AC (50–60 Hz) Compatibility
The power supply uses a proprietary pinout that is not fully compatible with standard ATX power supplies . Attempting to use a standard ATX PSU without a proper adapter may damage the motherboard or the PSU itself. ps42419ha schematic top
Rectify the low-voltage AC to DC.
If your system is not turning on (no LED on the motherboard), check these specific areas on the board:
I will cite the sources appropriately. search term "ps42419ha schematic top" most often refers to the , a 240W power supply unit (PSU) widely used in the HP Elite 6000, 6005, 6200, 8000, 8100, and 8200 Small Form Factor (SFF) desktop series. It is a proprietary power supply designed to fit the compact cases of these business-class systems.
: How well is the schematic organized? Are the components clearly labeled and logically arranged? Is it easy to follow for someone trying to understand or replicate the circuit? +12VMAINpositive 12 cap V sub cap M cap
: Regulated via an optocoupler and a zener diode/TL431 shunt regulator array to isolate the primary high-voltage sector from the secondary low-voltage output. Proprietary Pinout Breakdown
A "schematic top" generally refers to the top-level diagram or physical layout view of the module's pinout and internal structure.

If you are looking for a replacement unit rather than a repair, this model is widely available through various retailers: HP Power Supply PS-4241-9HA 240W * - eBay : The PS-4241-9HA heavily utilizes the TNY279PN Power
A ceramic-body time-delay fuse protects the overall system from catastrophic overcurrent.
Look for the TNY279PN (an 18W to 20W IC). You can often find replacement chips on Electronics Parts Distributors or Mouser Electronics.
The HP PS-4241-9HA is a with a small form factor (SFF) design , measuring approximately 14.5 cm × 9.5 cm × 12.9 cm . It accepts a wide input voltage range of 100 V to 240 V AC , making it suitable for global use, and is specifically engineered for HP’s compact desktop chassis.
