    Delta dps-300sb doesn,t start no output no led

    just thought I would leave this tip for anyone with the above psu.
    in my case this psu would run perfectly one day and not start the next but leave it for a few hours and it would start again.
    when it wasn't working the green l.e.d. on the back of the psu remained out the fan did not turn and there was no power output.
    everything inside the psu looked clean, no blown caps etc.

    turned out to be C914 was under capacitance when removed and tested... replacing it fixed the psu

    found more info on this website

      In the 5VSB circuit? Or in the PWM circuit?
