Hi everyone o/, Im trying to fix an old mobo lga 775 that have bulged caps on it and I have no idea which capacitors to buy. The original ones are OST 680uF 4V I think is this one --> soo what should I check on the new ones ? they must be low ESR or same voltage and capacity etc?

Re: Chosing new caps
If they are on the CPU VCORE output, these should do fine (it should be safer to go one step lower in voltage if they are around the CPU):

The HNs linked below may be a better option if there's less margin in terms of voltage.Last edited by Wester547; 09-07-2016, 02:11 PM. -
Re: Chosing new caps
This old post is probably still relevant as to quality caps:

I am new to the forum but just discovered that this website has a store where you can buy the caps you need:
https://www.badcaps.net/store/index.php
The voltage rating can be higher than 4V, but the capacitance should be the same or as close as you can get. I think any caps you buy through this site will have reasonably low ESR characteristics.
You also need to check the size of your caps to make sure the new ones will fit on your motherboard. Your data sheet shows the 470uF capacitor to be 8mm Diameter x 12mm Height and the badcaps 470uF 10V Nichicon caps are the same dimensions.

Hope this helps. If you are new to motherboard repair, you might not realize the board could have other damage, so this could be a learning experience. I tried replacing motherboard caps about 10 years ago and it was a fail. I don't mean to discourage you, just a heads-up!Comment

by momakaI 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:

by eryjusHello,
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."

by Paxman_SwedeHello!
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...-

by captain150I'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,...-

by FoetussGood 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?...-
