Well i got the power link about 1 months ago! Last weekend i was playing SQUAD online and the video went black, the system was running, i got sound, but no video! after several tries with the same result, i took out the power link, and the same problem happened!
plugged some new (pigtail) pci-e cable on my EVGA RTX 2080 XC gaming but in a different PSU (Corsair AX 760) conector and no more problem.
Tonight i decided to investigate the problem, well the first PCI-E cable that was in powe link was burned in to the PSU side.
My doubt is that Power link was the reason for this happend??? as i use the system in the same way for 4 years.
Even my last cards was mounted with the same pigtail pci-e cable.
Just to be sure till i decide put the power link back, im using 2 different pci-e cables (singles ones) for each pic-e connectors of VGA.
cause i dont know if was coincidence, after short time using the power link, or a PIGTAIL slit pci-e cable, wasnt enough to power the RTX 2080!

Maybe this could be why Corsair AX 760? And why I no longer use Corsair Power Supplies.

same thing dude, look:  do you think that the problem is really the cables? did you checked if the PSU connectors was dammaged? cause im about to buy some mulltimeter to check that! Still very strange why power link ask to plug the both 8 pin but will only output 8+6 to the VGA ! 4 years using the PSU and 1 month, maybe 5 days of using power link this happened!

Yep! Look inside the Connector on the Power Supply and I bet you have some melted Pins as well. I would not use a Power Supply after this. So only One of the Two Cables look like this? My Corsair PSU was only 3 Years Old. Them RTX FTW3 Graphics Card Pull More Power then most think.

"1 cable with pigtails wasnt enought to the RTX 2080" This is Very True.
You need to use 2 PCIe Cables using One Connector from Each Cable.

+1 If you were using a single pigtail from the PSU into a slitter to the power link then it was user error in cabling judgement - you should have used 2 cable directly from the PSU If I am not correct the documentation for the GPU should have stated to use 2 pigtails = why they no longer supply a slitter with the cards I have a power link on my 1080ti FTW3 - have seen it pull 300+ watts without any issues - have had it in my system for a good 8 months now

Using two separate PCIe cables for Any performance GPU has been a "best practice" for years
The Power link did not "cause" the issue you are describing
Heat will concentrate where the resistance is highest in any electrical circuit, in this instance it appears the connection at the PSU was compromised. This would most likely indicate either a loose fit or the PSU safety circuit for overload failed.
I would send the PSU to the Mfg for Testing as you would not want to damage any other part of your Rig

Hmm this is actually kind of scary. Lucky for me I have an EVGA power supply so hopefully they are designed to work well with the powerlink

I've never had an issue with my powerlink, with either a Corsair or EVGA PSU. Hope you figure it out!

corsair replaced the PSU with a HX750i model! installed separed cables for VGA now, but looking over the web, a lot of ppl just use the pigtail.

All we can do is recommend, "A Best Practice" as stated above. If you have A Graphics Card with 2 Power Connectors then use 2 Separate PCIe Power Cables. It is your hardware and your Choice in the end.

I've been having trouble with my screen going black with audio continuing for a moment, then the system (as far as I can tell) locking up. When I reboot (or it does) the screen goes black as soon as Windows starts and the fans go up to full speed on the card (GTX 1080 TI SC Black Edition Gaming.) Well, having replaced the card, wiped and reinstalled the drivers, replacing the actual power cable to the power supply I was getting desperate. I noticed that the Power Link was hard to remove and insert and decided that it's possible that it was the problem. I removed it, the power cables from the power supply weren't obviously damaged but I swapped the two where the one that used 6 was now the 8 pin and vice versa, not sure if this was even remotely a factor. I'm inclined to believe that the Power Link was the culprit as the system hasn't crashed since performing this task despite running the same games that crashed it regularly before. I'm not sure if I'm going to try to replace this device as, unless they've revised it, I believe it to be the problem. I recommend that it be removed as I think it simply can't handle the heat.
