it's incredible...
 
One is Conductive Polymer Tantalum Solid Capacitors (POSCAP)
 
the other is 
 
Conductive Polymer Aluminum Electrolytic Capacitors (SP-Cap)
 
 No one considers or notices that they are talking about the wrong subject.



It really doesn’t matter for our purposes, though. The terminology was used by Igor and now others are using it. I don’t know that EVGA’s (or anybody’) electrical engineers/board designers are commenting here to correct the dialog.
 
As you point out, the markings are pretty cryptic and sparse. When surface mount components come out of the carrying tape/reel, it’s tough to know much about the component without measurements. There’s also a language barrier involved.
 
What matters is there are two different kinds of caps, two different reasons for being there. The MLCCs are likely there to filter the high frequency switching noise, and the poly caps are probably there for ripple. And even the true purpose doesn’t matter. What matters is the poly caps didn’t seem to do a good enough job for whatever reason and the MLCCs were needed to reduce the remaining noise even more.




 
So what d u think about this:  https://youtu.be/GPFKS8jNNh0
 




Yeah it's the wrong terminology, but you can tell who is just parroting the article and who actually knows something about electronics.  They are just Tantalum and Ceramic caps as far as I'm concerned.

Jacob,
Are the 3090's FTW3's affected also, or is the solution already addressed on them.

I seems that the 3090 XC3 was updated to the 4x2 design as I snagged one on launch day and it’s has only 4 POSCAPS with 2 MLCC. Here is a pic...

You are correct. Fixed now.

The EVGA RTX 3080 FTW3 ULTRA Gaming stock photos still show the 6 POSCAPs instead of 4 + 2.


Have a link?  I looked at the product page and it's changed.  If you've looked at it before, maybe you need to clear your cache. That's what Jacob was recommending if you're still seeing the stock photo.

 
Yup, you are right my friend, I needed to clear the cache, I didn't realize it was still displaying the old photo even though I was refreshing the page... damn cache. Thanks for the tip, looks ok now (4 POSCAPs + 2 MLCCs) :)

Guys watch a video from Igor’s Lab and are now electrical engineers lol.

So the XC3 only has one set of MLCC, but the ftw needs two sets? Seems like a good idea to cancel my order if nothing new comes up...

I was so excited I scored a XC3 Ultra from Amazon I honestly just dropped any and all 3080 news immediately.
 
Jacob mentions the XC3 should be fine, but have their been reports of issues with it?
