Recap a single bad cap?

Re: Recap a single bad cap?

You don't want either KZJ or KZG.
Those two don't like heat at all.
They use the same electrolyte and that's their problem.
As to your question:
KZJ handles more ripple and has lower ESR that KZG.

KZG is comparable to Rubycon MBZ, Sanyo WG, and in 10mm Panasonic FJ
KZJ is comparable to Rubycon MCZ.
Panasonic FJ in 8mm are between KZG and KZJ.

Yup, Panasonic FJ is ultra-low ESR, and seems to handle heat better - I haven't encountered a single failure to date. The 1800/16/10mm is a very good universal 10mm motherboard cap, which can be used on any rail and just about any location.

Re: Recap a single bad cap?

I see... The KZG that has blown is 6.3V 820uF.. Right up near near the ram slot.. Any suggestions on replacement??

Re: Recap a single bad cap?

8mm or 10mm ?

Re: Recap a single bad cap?

Im going to assume its 8mm..

Re: Recap a single bad cap?

Oops.
I did 1000uF not 820

At one time or another I've gotten caps from all three of these places.
The one in the middle will probably get them into your hands quickest.

Re: Recap a single bad cap?

Thanks for the info guys.. Any recommendations for mini caps? The 1 that is blown is very small in height.. Not much higher than the ram slot..

Thanks..

Re: Recap a single bad cap?

I just purchased some 8x12 Rubycon MCZ... 6.3V 820uF..

Hopefully nothing else goes in the meantime..

Thanks all..

Re: Recap a single bad cap?

Here is a picture..

I imagine it's pretty hot right between those MOSFETs and the RAM.
Not a good spot for KZG.

.

By mini-cap I assume you mean the 680uF 4v?
Will either of these fit?

Re: Recap a single bad cap?

I see only a 20 pin power supply in one of those pics which means it could be old. I would check to see if any caps are bad in the power supply which may be causing excessive stress and heat to the mainboard.

Re: Recap a single bad cap?

I checked the PSU and they all seemed fine.. Rubycons on the input.. I don't have equipment to actually test them.. The heat is caused from folding proteins all day long... I pulled out a ram stick but added a gpu.. Correct with 20 pin.. Its a Delta Electronics 300w\350w I think.. I diddn't like it having to power a pentium d it came with ended up swapping witha buddy to get cash etc for other comps..There is a Celeron D in there atm..

The caps I got were these.. Ordered from The Cap King (http://www.thecapking.com/)
Rubycon MCZ 820uf 6.3v 8mm
Rubycon part number: 6.3MCZ820M8X12
K vent on top
A0826 105 T0902 105

Pretty much perfect sized replacement.. No more visibly bad caps at the moment..

Thansk All..

Re: Recap a single bad cap?

Strange, I thought motherboards with 24pin ATX were mandatory to use 24pin PSU?

I'm pretty sure mine was.

Re: Recap a single bad cap?

Only some are.
The reason for the added wires is to pass more amps.
Some boards use the 24pin for compatibility with PSU plugs but don't actually need the added amps.
