    I'm trying to draw a schematic of the supply I cant find that on the net either.
    I have Searched the Internet for days until my fingers are bloody.
    No Luck finding a Data sheet for it. It's in the Low voltage section.
    I think its a Voltage monitor for the various voltages 5 12 3.3 etc.

    Here is the Schematic of the Supervisor Board the HP1002WA is part of.
    Tried again still no luck finding the data sheet on the chip.
    You can kind of tell what its doing by the Schematic.

    I have come across this chip before. It checks for assorted error conditions - overvoltage, undervoltage, stuff like that - and shuts down the supply if it finds a problem.

    Picked up a HIPRO 300w power supply from goodwill for 1$.
    I think it has the same Supervisor Chip as the 250w one.
    The chip number is TPS3514 If you compare the Schematic I drew and the 3514 they match pin for pin
