Hey there,
My motherboard (Asus A7N8X-DX) seems to have finally failed. It will no longer POST, and although it turns on, nothing happens, no beeps, just sits there. I have determined its due to bad caps since about 7 of 9 of the larger caps (3300 uF, 6.3V) have bulged and/or are leaking electrolyte. The problems had been getting progressively worse until now it just won't boot.
I plan to recap this board and hopefully this should fix the problems. My question is, I have a bunch of United Chemicon KMG series caps that could replace the caps. The caps that are bad are near the processor/bridge (I believe this is VRM?). Can I use these caps I have? How bad is it to use non-low-ESR caps, or should I just get some low ESR ones? Here is the datasheet for KMG series:
If I do decide to get some Low ESR caps, I sourced some potential options that would be the most easily available. I can get:
United Chemicon KY or KZE (6.3V)
Panasonic FC or FM (6.3V, both more expensive than chemicons)
Nichicon PW or HE (10V, also more expensive than chemicon)
Which is preferable of the above? All have a minimum diameter of 12.5mm which isn't great but is probably doable. The KMGs I have are 10mm diameter, but yeah, dunno if they'll be good enough.
Any help is appreciated.
