Power Supply for 8 GPU Rig

What is the best power supply to use for an 8-GPU rig?

Will be using 8 RX 580’s and want to make sure I have enough juice to keep them all running.

1200psu for gpu, 700watt for mobo and risers

I really like server power supplies with a breakout board than going with a consumer power supply. I have a used parallel miner. You can do a quick google search to find them or a competitor. Newegg also have them.
