Ok, so im sorry if this has already been posted but i find mixed discussion on the topic.
I'm fortunate enough to have a spankin new GTX 980TI Lightning.
I recently upgraded to an Acer Predator (27 in 144hz 1440P with G-Sync). Since then i have had all kinds of issues with games freezing up (Fallout 4 and Metro).
After hours of different attempts at fixing the issue i finally read a post that suggested i had the GPU powered incorrectly.
The LIGHTNING (as far as i know) is the only 980Ti that requires TWO 8 AND one 6 pin power connections.
The suggestion was that i needed to have individual power cables connected to my PSU. I have previously read that it is OK to use a Power cable that connects 8 pins to the PSU but then splits into an 8 (6+2) and a 6 pin. Once i connected a separate cable to each connection (so a total of 3 separate cables) my crashing and stalling issues went away.
So my question is...
why is there so many people suggesting that it is ok to use a split 12V power cable that has a 6+2 AND a 6 pin when it seems to become a problem when you try to use 1440p monitors vs. 1080p.
I have actually seen an increase in FPS since i made this change. so i guess the only other problem is that my PSU only has 4 power slots so if i SLI in the future i am going to have to hope they make PSU's that have 6.
Any help understanding these GPU power cables would be awesome. Why do they even make a power cable that has an 8 (6+2) and a 6 if only one should be used at a time.
