    Hi, im going to make something new of the powersupply but i got an issue...
    When i plug it in the outlett, the powersupply automaticly turns on and i cant turn it of.
    Usally you should use a paper clip (Or cable) To jumpstart it from the green cable to a black one, and the green signal cable is supposed to have 5V but my multi meter shows 0... What is wrong?
    Model: HP DPS-460CB

    Some PC PSU require a load on the outputs to get going.

    With the power disconnected, what resistance do you measure between the green wire and a black wire?

    Do you have 5V between the purple and black wires?
