Why would any company release a product to cater to the competition, especially when it is a very inexpensive accessory?

It would cost far more than it would benefit to cater to users that want these for a different manufacturer. The next request would be to remove the EVGA branding so it doesn’t interfere with an ASUS/MSI/Palit/Gigabyte/***** (not vulgar, * placed so users can insert any name they want) GPU. It may be best to ask other manufacturers to engineer a like product for their own lineup.

Already a HUGE mark up on this item. If they made adjustable one, they could make way more money.
 
Still trying to find out if the PCIE cables evga used for the test had a capacitor in them or not.

 
How HUGE of a markup?  I haven't seen the cost of making these items, and I know they gave quite a few of them away with a promotion during the 1070/1080/1080ti lifetime.  
 
I wouldn't have the answer to that question, but I am sure if EVGA wants to answer, they will reply. I would assume they tested it across numerous different power supplies and cables to verify their results.
 
If users are comfortable modifying, I am sure that someone could easily figure out how to make it work themselves.. I mean, it's already been done once, and the user even showed exactly what to do.

It's not Johnny Guru making the claim without mentioning PCIE cable used. If Johnny Guru did the testing, they would give us way more information. It shouldn't be too hard for EVGA to clarify if they used PCIE cables with capacitor in them or not. the PowerLink has 2 capacitor in it. Is the difference evga is showing, with a capacitor vs not having any? 
 
I don't get why forum moderators feel the need to deflect for EVGA.

To be fair, it's easy to see the difference on the oscilloscope, but the test is almost certainly flawed and therefore the difference we "see" is completely irrelevant.
 
The bulk capacitors are added near the end of the lead near the PCI-E connectors.  Then, they measure how much more stable the voltage is at the PCI-E connectors.  Of course it is more stable!  But what difference does it make?  Absolutely no difference at all.  The stability of the voltage at the PSU side is going to be the same (longish wires and inductance make the affect of the capacitors undetectable).  And the stability of the voltage output of the VRM into the GPU core and GPU memory is going to be the same.  The only difference is that the voltage stability at the PCI-E connectors is more stable and the voltage input to the VRM is slightly more stable.  So?  Is the voltage stability of the connectors important?  Absolutely not.  Inches away from the connectors, the voltage is purposely chopped up into all sorts of high frequency pulses.  It's the filtering out of the VRM which matters; and this product has virtually no affect on that.
 
This can be easily demonstrated and, if you already own the equipment (the computer with high powered video card and oscilliscope), it can be demonstrated for a dollar or less.  Someone should pester Actually Hardcore Overclocking to prove that this product does nothing.
 
My oscilloscope is is too basic and restricted for you to accept any data that I could collect.  And I don't want to take the backplate off of my video card to do the necessary probing.  But I know enough about bulk capacitance, bypass capacitors, and VRM to know that this product is a form of snake oil.  The test/demonstration is specifically designed to make you believe that it does something useful.

But those tests you mention, from earlier in the video, are different than the subject of this thread.  Those tests had bulk bypass capacitors mounted directly to the back of the components and then measured how smooth the voltage is.  In other words, those tests were for adding capacitance AFTER the output of the VRM.  This thing we are talking about in this thread is bulk capacitors added far from the components BEFORE the VRM.  The part of the video I mentioned was the small part where he talked about his testing of adding capacitors before the VRM and how it does nothing except only if your power supply is absolutely terrible (in which case you should replace the power supply for many reasons [safety, reliability, etcetera] instead of adding bulk capacitors to the power supply output).
 
Adding too much bulk capacitance to the power supply output can actually cause issues and cause the power-on and power-off signals to no longer meet ATX specifications (if using a very energy efficient computer and/or getting absolutely crazy about adding bulk capacitance).  Adding the capacitance AFTER the VRM can help and doesn't cause issues with meeting ATX specifications.  Adding the capacitance BEFORE the VRM does nothing useful.
 
It would be nice to see this proven by a professional, but the outcome is already apparent.

Yes, of course You should buy PowerLink then pay for it and pay for its shipping. Then wait for delivery and hope You will be more lucky than me ´cause I am waiting several years aready. And company with best customer services don´t resolve it, nor refund despite my severel notice.

Really?

Yes, really. I never joking about such serious thing.

You will receive an email when your EVGA PowerLink(s) have shipped.
Email with shipping notice wasn´t delivered nor PowerLinks itself. So I twice contact customer support but without any result and so I sadly finish with EVGA. I was, maybe I still am, Elite member, from 2012 I bought almost every generation top EVGA edition of nVidia GC (GTX680SC Signature 2, GTX980 Superclocked ACX 2.0, GTX 1080 FTW GAMING ACX 3.0, GTX 1080 CLASSIFIED GAMING ACX 3.0 and EVGA GeForce GTX 1080 Ti FTW3 GAMING) and about 10 another EVGA card for my friends. I am only small private customer, so why care about lost me, right? So my new RTX2080Ti is AORUS.

Contact support again? Why?
