Hello gamers, this bad boy arrived today and it's the first time I've encountered 3 PCIe power slots. I'm familiar with using 1 cable and using the daisy chained 8 pin to handle the 2 slots. Since my Gigabyte 80+ G 1000W came with 3 of these PCIe cables I'm assuming this setup is correct? I'm probably needlessly worrying that I'll brick this.

To be exact, each cable is an 2+6 pin into the PSU while the opposite end is 2 (daisy chained) 2+6 pins. My worry is rooted in not being familiar with the daisy chained bits importance.
