What is the temperature spec of your newly bought cap ? 85 or 105 deg C.

In switching power supply all output cap must be Low-ESR (identified by temperature rating of 105 dec C)

85 deg C cap cannot be used in power supply as it will burst very fast because of high ESR.

You can google what is ESR.

講緊如果同牌子同物料同rating, 通常細貴過大, 可能你見果兩隻仲有D野唔同喎, 同係 16V1000u, 都仲有第二D spec 喎 e.g. Temp.
冇相睇好難話邊粒好D
如果兩粒size方面你都啱用, 就唔係話要大D定細D喇, 要睇detail d 先知邊粒好D

470uF 16V D8mm? or D10mm?

I want to know you buy what kind of caps and brand more than the size problem.
