You'll need to plug 2x 8 pin connectors into your 1080ti, then one 6 pin into your riser, and the usb of the riser into your MOBO.
If you dont have enough 6/8pin connectors, you can use the supplied sata - 6 pin adapter provided with the risers, it's not recommended though as they have been known to melt. I've used them on some cards for a while though no problem, but be aware it can cause issues.

Thanks for the reply, so I should buy a few extra of these?

If your PSU doesn't have 8pins, Yes, you should buy those splitters, take note that 1080ti's also draws a lot of power, ensure you have enough Psu watts rating to handle those beast.
