Asus A8V Deluxe 2.00 Recap

[panegiricus]

Hi people, i would recap this mobo, found in an old office system.
When i try it, the mobo don't want to take bios configuration and it don't find the sata disk plugged, if i enter in bios and i save the configuration, the mobo find the disk and all right. I put a new CR2032 battery and I flash the newest bios (i find a very early), the mobo don't want to find the disk after a shutdown, after hours of correct works. i must ctrl-alt-del to let the mobo find sata disk correctly.
I would try to recover it with a good recap.
The mobo have

20 x 820uF 6.3v FJ
4 x 1000uF 16v KZG
6 x 1500uF 6.3 KZG
9 x 100uf 6.3 (that i don't think to recap)

I can't find Panasonic FJ and Nippon Chemicon KZG Caps, i can find:

Panasonic FC,FM,FR
Rubycon YK,YXA,YXF,YXH,YXJ,ZL,ZLH,ZLJ
Nic Components NRSZ NRZJ
Nichicon BT,BX,PS,PW,PX,VR,VY

From what it sounds like, it seems that your hard disk is at fault here... check if the bios has a hard disk spinup delay or such. It may just be that your hard disk takes a little too long to spin up for the board to recognize it.

Do you think it can be motherboard related?

Re: Asus A8V Deluxe 2.00 Recap

None of those series are adequate as a replacement...

4 x 1000uF 16v KZG
6 x 1500uF 6.3 KZG

I am assuming these are 10mm in width, correct? If so, here are the replacements:
1) https://www.badcaps.net/store/produc...roducts_id=174
2) https://www.badcaps.net/store/produc...roducts_id=147

Leave the Panasonic FJ and the small 100uF caps alone.

may the 820uF be "immortal"?

Re: Asus A8V Deluxe 2.00 Recap

The 820uF shouldn't be aproblem for two reasons:

1) They're Panasonic "FJ" series... FJ is a reliable series for the most part, and they usually do not need replacing.
2) They're not in the VRM, which means that there shouldn't be a lot of ripple passing through them, and more importantly, not as much heat as the VRM caps.

The "KZG" series are completely unreliable, even when they are not used in a VRM, so these should be replaced no matter what, especially in your case.

You should check the PSU as well.

Re: Asus A8V Deluxe 2.00 Recap

Those 1500uF 6.3v KZG caps are probably 8mm Diameter. If so, use https://www.badcaps.net/store/produc...roducts_id=136 to replace them.

The 820uF caps shouldn't need replacing, as mockingbird said, but if you had some extra time to kill, then https://www.badcaps.net/store/produc...roducts_id=163 would be an appropriate replacement.
