Hey guys -

Just had a quick question. I bought EVGA 1070 Ti (w/o back plate) recently and noticed it only have 8 pin power connector. I used to have R9 390 which had 2x8 pin connector. Also noticed EVGA 1070 Ti with back plate have 2x8 pin power connector as well.

What does it really mean when you are using less power connector? Does it lower the performance of the GPU in any way?

A typical GTX1070ti will have a 6 and an 8 pin power connector.
A highly overclocked version might need two 8 pin connectors.
Backplates are sometimes offered on higher end cards, supposedly to improve cooling.

Having fewer or smaller power connectors on a card simply means that it does not need more.
If you look at the boost clocks, you will see that better(and pricier) cards perform a bit better and need more power.

No, it doesn't lower performance. Some cards with more connectors may overclock slightly higher....or, at least will spread the load more while overclocked. An 8 pin can supply 150w and the PCIe slot supplies up to 75w, so that's 225w. The 1070 Ti requires 180w.
