MP 1,1-5,1 Power supply for a Radeon RX 570 on a Mac Pro

Hi,
I run Mojave on a MacPro 5,1 with an un-flashed Radeon RX560 with no problem except the normal lack of access while booting up. I just got a flashed RX570 and I am wondering how much power does that card need? The new card came with a mini 6 to 6 pins. Is that enough or should I use both power inputs on my Mac?
Thanks in advance for any input.

A mini 6pin is enough a power a 6pin on the card.
