Just wanted to post this, so there's some record/precedent of it, in case anyone else looks it up.
My 2 months old, custom build:
- EVGA GTX 1060 &GB ACX 2.0
- Intel i5 6400 + Coolermaster 212 EVO
- 16GB HperX Ram
- Gigabyte B150m-d3h MB
- EVGA 600W Bronze 80 Plus PSU
- Thermaltake Commander Case
- Samsung 850 EVO 500GB SSD
How it happened: Normal gaming usage for a couple of hours with GPU running at 75°c and CPU running at 28°c. Suddenly PC turns off (coolers, fan, mobo led, these are all off), however the case LED and my RBG keyboard are still on, so I figured my OS froze. I restart the computer and BAM, sparks and fire come out the GPU, I quickly unplug the PSU and the fire goes out within a second. Lots of smoke that smells like some serious welding had just gone on, I leave the room. Back a few moments later when things have ventilated I pull the GPU out and take the picture (attached). After a quick review, I restart the computer again (without the GPU), boots up no problem and proceeds to install on-board intel graphic drivers (sob).
Have already started a ticket in order to request RMA.
