First time miner here, I have some questions :)

Hi guys, just got into mining and i chose raven, Started mining it on single RX 570, few days after I bought another 570 for the start.

I have some PSU issues, too many people telling me different things so i gotta ask you guys becouse i trust you the most.

1. Is it safe to power two 570's with one dual 8pin?
2. Is it safe to power one 570 with 2 molex to 8pin?
3. Is it safe to power 2 risers with one dual molex?

I have a brend new Seasonic GC650, and it's non modular, has only two dual 8pins and 1 triple molex cable, didn't check when i ordered it : /

Thanks in advance!!!
