Re: Can PSUs Cause Bad Caps?
really. the newer ones i heard were holding up better in power supplies, like teapo. honestly.
the old ones are shit, i know that.
the one i have now still runs great... i put in my dad's computer... if it was shit, i would not be giving it to him...sigpic

Re: Can PSUs Cause Bad Caps?
RLS isn't new.
Neither is a PSU that went in production in '05 and out of production in '06.
If I look around I probably even have some bloated RLS from '05 & '06.
I had a batch of FSP units loaded with them.Mann-Made Global Warming.

Re: Can PSUs Cause Bad Caps?
OST has always been similar to Teapo and LTEC. Can be OK in a well cooled PSU but Only Some Trash on motherboards. Personally, they are not up to my quality standards so I re-cap all three of those brands in a PSU I intend on using/keeping, bloated or not.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Can PSUs Cause Bad Caps?
Have any of you seen any solid state capacitors in PSUs or motherboards go bad?
Some companies advertise how they use Japanese solid state capacitors with their products. Are all brands of Japanese solid state capacitors generally regarded as high quality caps?Comment

Re: Can PSUs Cause Bad Caps?
Solid State Capacitors would be capacitors formed into the silicon in IC chips..
-- RAM and is essentially banks of Solid State Capacitors.
-- Flash memory [including that in a BIOS Chip] is the same as RAM in that.
So when you see bad RAM or a bad BIOS chip you are seeing bad Solid State Capacitors.
Solid Polymer, Functional Polymer, and Organic Polymer caps [as various manufacturers call them] aren't solid state parts despite various advertising campaigns.
Any part can fail.
The failure rate of the various Polymer cap varieties is very low...
... probably somewhere around what it is for transformers.
~~~
Watch out for electrolytics that -look like- Polymer but aren't.
Sacon FZ are the the famous one but there are many others that don't get noticed because they don't fail in droves like the Sacons.

A while back I thought Capxon had 'become okay' in PSUs too but I've revisited that idea and changed my mind.
Seen too many blown Capxon in LCD's & TV PSUs w/ dates as new as 2008. Last week I cracked open an FSP 700 watt [built late 2006] and its packed with swollen Capxons. [The damned things are 8mm x around 30mm at 2200uF ... WTF-over?]
I see less OST than Capxon these days so I see less bad OST than Capxon.
... But if I see 100 Capxon and then 100 OST the - % - of either that is failed would be about the same. [My guess is about 50%.]
... If I added 100 Teapo to that comparison there the failure rate for Teapo would probably be less than 5%. [Better but not great.]
[But anymore Teapos mostly show up as primaries or 6.3mm and smaller caps except in total crap brand PSUs.]

Re: Can PSUs Cause Bad Caps?
I have yet to see one of these AcBel units fail, in the 2 or so years I've been using them. Of course that doesn't mean that they won't fail at some point, but so far they've worked fine.
OBTW, concerning the 70% efficiency. That is probably a worst-case number, similar to their stated ripple specs. I can tell you that running in my computer this AcBel is nowhere near as high on ripple as they rate it.A man convinced against his will is of the same opinion still.Comment

Re: Can PSUs Cause Bad Caps?
Ads always give peak [best] efficiency.
That usually occurs at around 75-80% of rated max load.
It's less above and below that.

Would they not be considered to be lying if they published that efficiency was greater than or equal to 70% when it wasn't?
Then why even publish it?A man convinced against his will is of the same opinion still.Comment

They don't want to say 73% and then get sued because some units only manage 71%.Mann-Made Global Warming.

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?... -
I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)
So, here is the...
