SAMXON GF(M) 10V 4700uF ripple?

[Orpheous]

Just pulled apart a failing Cooler Master 650W pc power supply and found a bulging SAMXON GF cap... I checked the datasheet for the GF series and it doesn't seem to list anything for a 4700uF 10V product.
Just wondering if anyone out there might have info on it so I can replace it with something suitable, or perhaps suggest an alternative?

diameter & height?

12.5mm x approx 30mm

around 2200ma
esr about 0.030

panasonic FR kicks it's ass on performance in all figures.
maybe a little too much - hard to say.

esr is about the same with the FR's, but ripple rating is 3630 according to their datasheet. Should I be trying to stick closer to the GF figures or will a much higher ripple be ok?

higher ripple handling is always best.

Thank you for taking the time to reply, I'll order a couple of FR caps to replace the two GF's on the board.
The rest of the caps on it are SAMXON KM(M)'s, so I'm not overly impressed with what I paid for a Cooler Master product, even if it was a few years ago! At least there doesn't seem to be anything visually wrong with the rest of them...

GF's are known to fail on intel motherboards - so we know about them!

I haven't read anything good about them! Not too many complaints about the KM series though, so I might just leave them in and get a better quality PSU next time

Not to mention monitor & TV power supplies...

Is it too politically incorrect for me to admit that I giggled a little when I realized that this won't be the first time I've ditched GF's once they start to bulge? :P

they usually fail without any external signs - something else they have in common with women!

All bad GFs I have ever seen were bulged. And I've seen some already.

Too much lower ESR over original is never a good thing for PSUs (oscillation etc.). (Sometimes it makes very little difference if you put lower ESR or higher ESR in there, lower capacity or higher capacity, the PSU just does not care.) One would already expect you got some knowledge of using too low ESR in PSU after 13k posts, but I just guess you troll in off topic section.

I plan on stocking 4700/6.3 D10x25 later on, hopefully this year…
