Re: Replacing capacitors with higher voltage rating

ESR and ripple?

It seems that I have two options.

1. research ESR and ripple pertaining to capacitors. Determine the ESR and ripple of original capacitors. Then find new capacitors that have similar characteristics of original capacitors.

OR

2. just buy some Rubycon 6.3volt 820uF capacitors and hope for the best.

The motherboard is from a Dell 8400 series.

Must say that this website has provided me with some insights.

i came across a motherboard with eight bad capacitors. They are located near the cpu. The original capacitors are rated at 4 volts 820 uF. Can I replace them with 6.3volt 820uF capacitors? I willing to read any other suggestions.

Thanks for your time.
