I have a ML350 G5 that I have already replaced all the caps on, but the three above the ram slots are leaking again after about two years. That part of the board gets extremely hot, so I'm trying to find poly alternatives to use up there. After examining some pictures of the motherboard I realized some newer models replaced some of the failure prone caps with poly, and I can see they used 16v 270uF. What I can't see is any of the identifying marks to reference the specs. Can anyone with one of these servers and the newer motherboard please post the detailed specs of those caps?

Re: HP ML350 G5 - need help with caps above RAM slots
Rather than waiting for someone to open up their server and take pictures, I think you can get more help if you give us some details on your motherboard (and pictures too if possible). In particular, what caps were there originally on the motherboard before you replaced them (brand, series, capacitance, voltage, and case size) and what did you replace them with?
And since you know the newer motherboards use 270 uF polymers, then perhaps the more important question is, what is the diameter of the failed caps (in mm)?
In general, you have quite a few choices of polymer brands and series...
Brand: series...
Nichicon : LF, LG, FPCAP R5, FPCAP R7, FPCAP L8, FPCAP NS and a few others
United Chemicon: PSC, PSA, PS, PSG, and PSF
Panasonic: OS-CON series (formerly made by Sanyo)... SEP, SEPC, and SEPF
Here is one possible choice that will work

it is a 330 uF cap, but it should be no problem at all... as long as it fits, that is. It has a 10 mm diameter.Last edited by momaka; 06-03-2015, 05:40 PM. -
Re: HP ML350 G5 - need help with caps above RAM slots
I actually have two threads going about this with two different tactics for identification. (https://www.badcaps.net/forum/showthread.php?t=46785) I was able to source crappy pics of the caps in question from another thread on here, and it was enough to get a match on United Chemicon for the brand. Based on extrapolated dimensions, I'm assuming the part number is APSF160ELL271MHB5S and ordered 13 of them.Comment

United Chemicon PSF should work fine. But any of the series I listed above will work too.Comment

First three caps are replaced and working great so far. If it makes it through the night without a hitch I will continue to replace the rest.Comment

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
Good evening
I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?
But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?...
