Hey guys,
I just picked up an EVGA 1080 FTW about a week ago to replace my R9 290. The card works perfectly 99% of the time, but I've had 3 times now when the system has just completey powered off, and started itself back up a few seconds later while gaming for about an hour+ while the card was overclocked. The settings I used were +100mhz core, +100mhz memory and 120% power limit. Now, the obvious guess that a lot of people would go to is the power supply, but I just find it hard to believe because I never had this issue with my heavily overclocked R9 290 (though that was an 8+6pin vs this card which is 8+8) that it replaced. The R9 290 tended to be far more power hungry though, but maybe stressed the power supply differently. So is the issue the card or the PSU? I was able to replicate the issue by running furmark with the overclock settings. I guess one of the obvious solutions is to back the overclock settings off, but if this overclock has exposed a weakness/failing PSU, I would rather deal with it now. What do you guys think? RMA the psu? Is there an issue with the card? The other odd thing I've found with the card is that when overclocking, I rarely ever see artifacting, the program will be running absolutely fine and then the program will either crash or the video driver will stop responding, which isn't quite the same thing that I used to see in older GPUs.
Also wanted to add that the card has the new bios with the increased fan curve as well as the thermal pads for VRM cooling, at least according to the EVGA website (serial # check).
My specs:
i5 4670K @ 4.2ghz
Gigabyte GA-Z87X-D3H mobo
8GB DDR3
EVGA GTX 1080 FTW
HX 850 Corsair power supply
