Hi,
Recently I gave a shot at recapping this Excellent power IT ATX 300 lc clone doohickey PSU. After I replaced all bulging caps and the 47uF 50v in 5vsb I turned it on. 5vsb and ps_on are spot on. So I shorted the ps_on and it dies after a split second. 5vsb still is generating, all other lines also generate voltage for a while but they all discharge so fast.
Now I am sure this isn't a problem with the 5vsb damaging the PWM IC or BJT circuit, but I have no idea where to go next. Maybe replacing all the smaller caps?
