Hi guy's/gal's! I've got a major problem whenever my 1080Ti FE (flashed for boot screen) hits heavy load and the whole mac just shut's off! This has only started happening recently but I haven't had the card long and I have set it up the way that I was told to when I bought it. with the 2 mini 6 pin connectors to the 8 pin and ta sata to 6 pin on the GPU. I was wondering if 1) Doing the Pixlas Mod would work and if so how much of a pain is it/can it be? And how long will it take? 2) I've also been looking down the route of a seperate PSU in the optical bay but what would I be able to do about the spare sata connection (Kinda want it for a spare 1TB HDD if I need to If someone with the knowledge that I clearly don't have could help then that would be grand!
