Specs:
CPU - Intel i7 7700k (stock)
Motherboard - GIGABYTE Aorus GA-Z270X-Gaming K7
RAM - G.SKILL Ripjaws V Series 16GB (2 x 8GB)
PSU - Raidmax RX-730SS 730W PSU
GPU - 2 x GIGABYTE GeForce GTX 1080 G1 Gaming GV-N1080G1 (SLI)
When using SLI with high/ultra settings in video games my computer screen goes black and becomes unresponsive. If I wait long enough the computer sometimes restarts by itself but usually I have to do it manually. There have been a few crashes where the fans start running at 100% during the black screen crash. If I run my games at a lower resolution / lower graphics settings then no crash occurs. I've desperately been searching for a fix through google for the last week and have been unable to resolve this issue. I'm hoping one of you can help me out with this.
So far I've tested each graphics card separately on ultra settings 4k resolution in Dragon Age Inquisition without crashing. When in SLI the temperatures for each card is about 60 to 68 degrees, the CPU temperatures average around 50, and the motherboard temperature sensors average around 55 to 60 (max of 70) before the crash occurs. From what I understand these temperatures are safe enough to not result in any kind of sudden reboot. Both the BIOS of the motherboard and GPUs are up to date as well as the GPU drivers.
From what I've gathered online, the GPUs being stock OC may cause issues so I under clocked both GPUs in an attempt to fix the issue which did not work. I've also read issues about CPU/RAM voltage issues when dealing with SLI but have not found a good source to try and change these values myself in the BIOS. The SLI bridge may also be the cause but considering the games run perfectly at lower settings this is probably not the issue. I've ordered a 1000W PSU which I hope will fix the issue.
Update: I've swapped out the PSU and no longer have any issues. Thanks for confirming my suspicions.
