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!
