We've seen some questions being raised regarding the PCIe 8-pin power connectors and why they were not connected at the time of the incident as well as questions regarding what the owner was doing at the time of the incident and why he was recording. We've addressed those questions in the original article in which this video was published. However, seeing as how some viewers haven't read the article we believed that we might as well share that information here so viewers can see it.

Mr. Duncan explained that he was using his phone as a light source to get a better view at the internals of the system whilst he was troubleshooting it, which is why he managed to record the incident when it took place.

Speaking to Wccftech.com Mr. Duncan said that his EVGA GTX 1080 FTW had been working without issue for one month prior to the incident. However, he explained that one day he came back home to find that all of a sudden his machine would no longer boot up when he attempted to turn it on.

This prompted him to investigate the issue, testing one part at a time. The auxiliary 8-pin and 6-pin power connectors were unplugged in the troubleshooting process. Although that in no way precludes the PCIe slot's 75 watt power delivery capability from powering up the graphics card. Which is why we clearly see the LED lights and the fans turn on before the VRMs suddenly caught fire.

Normally, what would happen if you unplug the PCIe power connectors is that the card would power on normally. In this case the system will boot up as long as the monitor is plugged into the motherboard's on-board graphics. However, if you have the monitor plugged into the graphics card, you will be greeted by an error screen reminding you to plug the power cables and restart. Or, you will hear a warning beep. In this case the card will also power on, but you won't get a video signal.

Mr. Duncan confirmed that the system refused to boot as long as the graphics card was installed with the monitor connected to it. Even with the PCIe power connectors plugged in. After all that's how he left them in the first place when his machine stopped working all of a sudden and prompted him to begin the troubleshooting process which he documented.

The GTX 1080 is an expensive piece of hardware. No one in their right mind, we believe, would intentionally destroy their GTX 1080 to fake a video. Furthermore, this is not an isolated incident. Reports of GTX 1080 and GTX 1070 cards catching fire are all over EVGA's forum and reddit. This is only one out of the many reported. Thankfully however, EVGA has already acknowledged the issue and has taken several steps to address it.
