I`m planning to add another graphics card to my computer.
I have rx 570 and it requires a 8 pin power connector. I have a power cable that has 8 (used by graphics card) and 6+2, so if I understood well 6+2 can be used as 6 or 8.
I will add another rx 570 and I`m not sure if the 8 and 6+2 power cable will give enoght juice for both.
PSU is a Corsair 650W, which powered a r9 290x before ( consuming the same as 2 rx 570 ).
