I just had a PSU crap out on me. Took it apart and found three fujjiyu 1000uf 10v caps that had gone bad. Looking in my parts bins, I found that I have three unused Sanyo 1000uf 10v caps, however they're physically smaller than the fujjiyu caps. Can I safely replace the larger caps with these smaller caps? I've never done a swap with smaller caps before and I'm hesitant to do it.

Re: replacing caps in a PSU, same spec, different size?
if the ESR is similar.
the size is not important providing they will fit. -
Re: replacing caps in a PSU, same spec, different size?
It depends how far off it is and how tolerant the PSU's feedback circuit is. It may work just fine, or it might make the ripple worse.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: replacing caps in a PSU, same spec, different size?
That's can mess it up? I just did this on my moms psu for her computer. There were 3 bulged. I had same spec ones to and it still had the same problem after.Comment

Re: replacing caps in a PSU, same spec, different size?
so the problem was deeper and the bad caps didnt cause the problem.
what's the symptoms.Comment

Re: replacing caps in a PSU, same spec, different size?
ugh... figures their documentation doesn't give a value for ESR.Comment

Re: replacing caps in a PSU, same spec, different size?
If that's the case, they are probably GP caps (not low ESR caps). If that's the case, I usually use Panasonic FC, Nichicon PW, NCC LXZ, Ruby YXF or something like that. You might get away with lower ESR than that or you might not. It depends a lot on the design of the PSU.Last edited by c_hegge; 05-30-2014, 03:54 AM.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: replacing caps in a PSU, same spec, different size?
Yeah, they're the TN series general purpose caps.
The PSU is a cheapie 300W PSU I picked up years ago, but it's the only one I have available that has a 12V P4 connector on it and the machine it was used in was still in service.
BAH... Guess I'll need to look into different caps.Comment

Assuming the original Fooljyyu's were 10mm diameter, any one of the following would work:

Re: replacing caps in a PSU, same spec, different size?
Rubycon ZL, ZLH or ZLG are worth considering - the ZLH is available in 1500uF/10V/8mm that fits in some fairly tight spots.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:

My 3.5 years old monitor (BenQ SW2700pt) started to black out for 1-2 sec every minute or so, it was doing this even with PC disconnected from it. I searched online and read that it's probably aging capacitors and there's a workaround to lower the brightness.
I lowered it from 100 to 65% and it indeed helped, but after a couple of months the issue returned... I continued to lower the brightness, but it helped only for a couple of hours at most, then I needed to lower it further... Turning the monitor off and waiting for it to cool down also helped for a short time, after which it... -
nichiconare what i used because i had heard the voltage doesn't matter as long as it is more than the original cap. i'm now reading that high voltage may make the cap's esr too high. is this a good cap for replacing those oem ones?1500 µF 16 V Aluminum - Polymer Capacitors Radial, Can 8mOhm 2000 Hrs @ 105°C -
I'm recapping an old Creative Labs / Cambridge speaker system / subwoofer. At 4:33 in this video, the person looking at what he says are the speaker caps in the system says they are 470 uF, and that he'd use much larger caps if he was building it.
https://youtu.be/1LRIzePlma0?t=273
I'm wondering if I should use something larger for the recap job, and what using larger caps will do for it.
Would 680uF be good value to try in place of the 470uF originals? -
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...
