Identifying bad capacitors part 2

I previously made a video about bad capacitors, but the quality of my old camera was horrible. This is a new video with my new camera, showing how to identify bad capacitors on a motherboard.

where can i buy the capacitor?

@interfixes mouser or ebay

On the broken board, the first one you showed, Is that stuff on the heat sink thermal paste? Looks like a clumsy job to me, unless, of course it is deliberate...

[mjmcomputers]

@XxxGamer5641xxX It's dust from where the processor heatsink and fan blew it on to that heatsink.

can a capacitor leak from the bottom? I've got black gunk leaking from the bottom of a capacitor and it has corroded other joints around it.

@bma852 Yes, especially the smaller ones, they tend to leak out the bottom and normally do alot of damage to the board.

820uF are common to pop on motherboard. Every motherboard with 820uF capacitors i have seen are either bulged or popped. It is hard to get 820uF caps so i use 1000uF and they work fine.

@mjmcomputers Ok, I get it!

@JBDenver I wouldn't change the capacitance value. You are safe to go higher on the voltage though. Have you tried mouser dot com?

I have a 6.3v 560uf fujitsu capacitor on my ASUS Rampage II Extreme Mobo. I have been trying to find a replacement for this capacitor and the best I can find is a 6.3v 680uf capacitor also by Fujitsu (Must be old, since they sold their manufacturing) If I put this one in, what are my risks?
