Hello, i have a Corsair TX850M 2017, I7 4790K and 16 Gigs of ram. I want to add 2 GTX 980 ti's and i want to know if the psu can handle. A lot of people blame this power suply for its "Great Wall" platform, but JonnyGuru says that is good. Beside that i have a GTX 1080 Strix but i have an offer where i can swap it for 2 980 ti's in exchange. I have an Asus MG248Q and i want to have the maximum fps for the 144Hz. PS: The 980 ti's are water cooled, and the cpu aswell.
 
Solution
One example is hellblade senua does not support sli, battlefield 1 in dx 12 does not support sli, doom vulkan does not support sli, you are much better with one gtx 1080 then 2 gtx 980 ti. When i made my sli set-up i had no option because the gtx 1080 was teh strongets card on the market then and i play at 4k so i had to add another one to play nice at 4k. SLI is recomended when you have the strongest (or almost the strongest) videocard on teh market and you need more power.

MultiGPU setup:
1. Not all games support
2. Performance scaling is game dependent
3. VRAM does not stuck
4. Consumes a lot of power
5. Has potential issues such as micro stutters, etc.

Go for multi-GPU only if you really can not find any better single GPU setup e.g. 2x GTX1080Ti, everything else does not make any sense
