Area-51 R4, PCIe power, 8 pin and 6+2 pin connectors the same thing?

Question

I have an Area-51 R4 (1500W PSU) with GTX 1080Ti and planning an upgrade to RTX 2080Ti. 1080Ti has 1x 6-pin and 1x 6+2-pin power connection. 2080Ti says it needs 2x 8-pin and 1x6-pin My PSU has another set of PCIE power cables (the same as connected to my 1080Ti) laying in the case which is nice:-).    From search here it looks like the =2-pins are just a ground - can it be as simple as using 2x 6+2-pin and 1x 6-pin. Apologies if this a really simple/dumb question, regards, Peter Existing 1080Ti connectionSpare PCIE power connector

The 6+2 connector can be connected to the 8 pin or 6 pin spot on the gpu. It makes the psu compatible with more gpus and cuts down the number of cables supplied with it.

2x 8-pin and 1x6-pin is over maximum power spec for PCI-E something wrong with that https://www.nvidia.com/en-us/geforce/graphics-cards/rtx-2080-ti/ Looks like 2X  8 pin connector is what it uses.

Thanks @speedstep, I probably should have been clearer, the card I am looking at is a MSI GeForce RTX 2080 Ti Gaming Z Trio HDMI 2xDP 11GB which I guess needs more power due to over-clocking.

Do you/anyone know if it is as simple as using 2x 6+2-pin and 1x 6-pin one the Area-51 R4 chassis?

Thanks, Peter
