Building a new PC for the first time in a long time and I don't recall coming across this before. My GPU has a spot for an 8-pin connector, my PSU's cable has two daisy chained 6+2 connectors with an 8-pin on the end. Is this for an SLI scenario, or does the GTX 1080 require the 8-pin in the GPU and the two 6+2 pins in the PSU to give it enough juice? I'm a little rusty and appreicate any feedback! Thanks, all.
