Well, I think it is my fault for not researching before actually do it. But here I am asking for help and advice because it didn't turn out how I visioned it to be. I got the ROG G20AJ with GTX 750, but want to upgrade to GTX 1060 SSC (EVGA). Will it work? Anyone done it? I need comfirmation on that.

Here's what I did: bought one additional power supply (180+240). The card only uses 120W max. I did set the jumpers, reset CMOS, and update to latest bios version (703). Then installed GTX1060 SSC, but nothing shows up on monitor. Only black screen. No "no signal" display either. I suspect that this might because of inefficient power supply because the GPU lights up and repeatedly spin and stop. (Maybe it is screaming, "I need more power! Power! Power!")

Any help is greatly appreciated in advance,
Nick
