Hello forum and thanks in advance for trying to help me.
I just bought a 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: https://imgur.com/a/9b96BwB
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 in my PSU 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.

Dear Jpaz90,
Thank you for choosing ASRock.
Regarding your case, please connect your PCI-e 6 Pin to power supply and connect PCI-e 6+2(8) Pin to the VEGA 56.

Thank you! Yours truly, ASRock TSD
