Problem after install GTX780

[LiquidX]

Hello all ,

I have recently bought Asus GTX 780 DCII OC. My PC screen will go blank when gaming especially when GPU power load up to 86%. When i reduce the load to target 75% (using GPU tweak), the problem goes away, but at the expand of gaming performance. RMA my PSU seasonic X750 but problem still persist. I have done my research that x750 gold 80plus is enough to run my system unless i am wrong. I run stock. Tried clean install driver and also using different cable on different jack of PSU. Pls help me.

Try increase volt by 0.012mv if you are gonna use 86% target load.

I doubt is the PSU issues.

Its more on your GPU.

Download Furmark Test. Run it. Monitor it for a while. See how it goes. Take note of the temperature graphs. Check also the GPU loading at the top right corner of the screen.
