    silverstone sst st50ef with bulged caps

    hello guys, i need your advice,
    here i have a PC with a weird behavior, occasionally it will start, with a delay,
    i push the power button, nothing happen, no light no spin, nothing, then 30 sec later the pc starts without me touching anything.
    i think the problem could come from the PSU, i opened it up and found 5 bulged caps, 3 teapo 2200uf 16v, and 2 others i cannot see the specs
    do you think there is a link between the bad caps and the delay the pc takes to start

    Yes, definitely the bulged caps are to blame of the delay. They may have high ESR and low capacitance. As the caps heat up, the ESR will drop allowing for the power supply to function.

    Replace all the capacitors, bulging or not with Panasonic FM/FR or some other low ESR caps from Rubycon, Nichicon or United Chemi-Con from a reputable distributor like digikey or mouser.

        Try heating the PSU with a hair dryer, it should start instantly.
