Re: Bad Rubycon caps in HP D530 SFF Motherboard

Whoops, I have found out that the polymer caps in the VRM area are actually Oscons, something y'all probably knew. But replacing the Rubycons with more Oscons doesn't appear to be an option as I can't even get close to a comparable capacitance.

Thanks everyone for your replies. I like to think myself somewhat handy with computers, but you guys are on a different level!

The CPU in the picture is a SL6PE Northwood core (sorry, gg1948). We could have Prescotts in other PCs as we bought a range from 2.4 to 2.8 Mhz, but I wonder if HP purposely avoided Prescotts?

What Teapos are you referring to, Leekh? I have 3 larger 16v/1200, and 10 6.3v/1000 scattered around, including 2 between the vented Rubycons and the northbridge. Or did you mean the solid...

I can't say for certain that heat is not an issue as we just started buying these models and don't have a long history with them. These small-form factor HP business PCs are not designed to be fiddled with by users - about the best you can hope for is all the fans keep working and the HP engineers did a proper job in the design. The D530s have one intake fan, a PSU fan, and a CPU fan that vents directly out the case.

Since HP sells a lot of these you'd expect a lot of chatter on the 'net if they put out...

Thanks kc8adu. Didn't have a camera available.

But now I do, so here are the pics......

Hi everyone. This is the first post from a newbie who found bad caps in some HP business PCs. BTW, love the great practical information on this site!

I just bought a lot of 27 PCs, Hewlitt Packard D530 SFF, from an off-lease reseller. While imaging them I found 6 units have bad capacitors either leaking or domed on top, in all cases they are near the CPU.

What's surprising is the failed caps are all Rubycon MCZ series, 6.3V/1800uf, which everyone here says are good. Who am I to disagree? But it makes me wonder if there is a design flaw in the motherboard or PSU that...
