which caps should I use to replace the FZ76 1500 6.3v on the e-GeForce 8500GT?
Would 1000 1200 or 1800 or 2200 for that matter.
Thanks!

Use the right size.
Those aren't even polymer so that size isn't the least bit hard to find.
.
Here is the specs.

Want caps with the same or less ESR and the same or more Ripple.

I'm new! I was told I could go up to 1800 or go down to 1200! Just want to make sure!Comment

Re: e-GeForce 8500GT 3 bad caps
If the ESR isn't appropriate then neither one.
You should be looking at ESR first. It's more important.
Whoever told you changing uF like that is -always- okay knows just enough to get you into trouble.
There is NO guarantee when changing uF.
If you want to -make sure- then draw out the circuit and do the math for it.
-
Some circuits are uF sensitive and others aren't.
-
Most designs can use caps +/-50% from the design optimum cap's uF .. but..
How do you know the 1500uF isn't already at +50%?
How do you know the 1500uF isn't already at -50%.?
Only the circuit designer knows if 1500uF is in the middle or on the edge.
If you want to know too then you have to do the math.
.
.
Odds are it's somewhere in the middle and a 20% change is okay. - But no guarantee.
Too ways to find out.
- Do the math. (very time consuming)
- Trial by fire. ('switch and pray' - possibility of damage or it not working)
And 1500uF caps are easy to find. - Why would you do either?
When you -HAVE- to change uF. [And this is not one of those times.]
Then go up in uF because uF goes down as caps age.
That means as it gets older the uF will get closer to the original value.
~
That said...
People that work with certain circuits all the time have a pretty good idea of what caps should be there and what they can change.
But what works in one kind of circuit doesn't always work in other kinds of circuits.
Video cards have dozens of kinds of circuits and all we know is it's a video card.
.

And again-
CHECK THE ESR - IT MATTERS.

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?...
