Help connecting Asrock Radeon RX VEGA 56 8GB HBM2 Phantom Gaming

Hello forum and helps in advance for trying to help me.

I just bought an Asrock Radeon RX VEGA 56 8GB HBM2 Phantom Gaming video card, but my power supply is a Cooler Master Silent Pro M700.


It is a modular power supply that has two Pci express 6 pin slots outgoing, and the video card needs an input of two 8 pin cables.


I've been going mad reading stuff in both manuals, but can't piece it together.


This is what the power supply user manual shows:


And all I could find in the Asrock web pages was that the card has 2 x 8-pin connectors (which I alredy know) and that the recommended PSU is 650W.


But I don't understand a lot about voltages and pc wiring, can someone please tell me how to connect it? My gut tells me to buy 2 cables with a 6 pin to 8 pin conversion, and plug both 6 pin ends into both my PSU outgoing slots and the other two 8 pin ends to the video card, but I don't know if this will overpower the card and might fry it, or perhaps that's exactly what must be done.


Can someone please help me? I'm sort of desperate.
