hi
i have corected all the problems in my 230W AT SMPS
and make it on and check there is only 0.33 V in 5V out put
after a moment new capacitor of 300 uF 250V burst there are two same value capacitor
what can be the problem what should i check first?

If it doesnt have an over voltage problem or a reverse polarity issue, calculate the ripple current for the capcitor and see by how much you are violating its specifications.
If it was over-voltage or reversed they would go straight away.
However, with ripple current it is the thermals that kill it. When the cap warms up its voltage rating reduces, so you end up killing it via overvolts eventaully.
