In the output stage of a power supply what would changing one electrolytic capacitor for a different value do. I have a D-Link DSL-2640B wireless router that stopped working and after taking the lid off of the power supply I see one of the electrolytic capacitors right next to the outlet cables has blown, it is a 300uf electrolytic, and I was wondering if I don't have a spare 300uf in my junk pile what will it alter if I replace it with the next nearest capacitor I can find give or take a few Uf.
This one is very strange as the power supply is still outputting the correct amount of voltage and powering up the router I.e all lights on the router light up however the said cap seems to have something to do with amperage as the supply is outputting 0 amps under load and is making the power light on the router stay red and not change into ready mode (green) so my assumption is the supply is not giving enough amps to kick something in due to the blown cap.
so again my question is will replacing the cap with either a smaller or larger Uf rated cap harm anything, I am assuming as I have narrowed this down to controlling output amperage that it will alter the amount of amps outputted with different values of cap.
