Hi all.

Today, unfortunately, I managed to fry my GTX 970. This was my first build, and I've been troubleshooting the crap out of it for the past two days. Initially started as a "POST, but no video display on the monitor" issue. Breadboard approach eventually allowed me to get the pre-BIOS screen up on the display, and everything was working wonderfully, save the GPU wasn't plugged in - I was using integrated graphics.

I go to tack on the GPU, set up the display adapter and the power connectors, then .. try and short the pins. Took me a few tries to power on the motherboard successfully, but once everything got rolling, I immediately noticed a "sizzling" sound, then rising smoke, then the smell of burnt components..

The smoke was rising from just behind the back panel of the GPU, where the DVI input is. I looked inside with a magnification / lamp stand to see if any capacitors were burnt out. I also tried to identify any burn marks on the backside of the GPU. Didn't notice anything out of place. I'm willing to post additional pictures.

My question: what do you think caused my GPU to fry? I dare not try to use it in my motherboard again out of fear of having the rest of the components die.

These are the available connectors on the top-side of the GPU:

8 pins, plus an additional six. I had it configured so that this PSU cable:

... could provide primary and supplementary power (6+2-pin connector and a 6-pin connector):

And this is what I was going off of. The wording, as well as the illustration, proved to be misleading for me:

Was there fault in the way that I configured this? Should I have just used the single 6+2-pin connector and left the other 6-pin connector vacant? Should I have used two 6-pin connections and left the the two auxiliary pins out of the way?

Thankfully I have completed the build. It just lacks a GPU and relies on the integrated graphics. I will be working through the BIOS later on tomorrow night after getting an additional SATA cable.

Thanks so much, and I hope to hear from you guys soon.
