Capacitor Replace

post #1 of 9
Thread Starter 
Can i replace a 250v 680uf capacitor with a 200v 680uf capacitor..?

i have a computer power supply with a capacitor of 250v 680uf blew up because i accidentally kept the voltage level low while i turned it on.. so is it possible to replace it with a low voltage and same resistance..



hope i will get a good answer..

Depends. What's the input voltage? 110V or 220V ?

Should be okay though.

are you sure?? 240V is the input voltage..

Then no. It will blow very quickly. Oh and it's not resistance, it's capacitance.

alright.. there are two capacitors right.. doesn't it mean 110v for the one that was damaged and 230v for the one that is ok.. does it work like that or not??

Nope, doesn't work like that. What you have now is an open circuit in your power supply. It's not going to work. You can buy that size capacitor for about $2-$5.

Replace both capacitors. Zwcon is not a reliable brand (as you've seen).
