How do I connect this 1070

[lolzdj]

So basically I decided to upgrade my 760 to a 1070 and everything's been going good except in nearly finished and I find out this power pin won't cut it. I have a 650 watt power supply and my pins are 2x 3 houses or something. Pls help

If you have only 6 pins PCIe cables , you will need this adapter for 8 pins PCIe cable
