Are you running the 2 pci-e off 1 physical cable? I have one connection to my PSU that has 2 PCI-e off it. I was running this way but read it was bad so I switched to having one pci-e cable off 2 molex connectors. Now I read that having the molex to pci-e isn't enough power and isn't safe. What would be the best method of powering them?

I would not use the molex to PCIx to power an Ant. The molex cables aren't designed to feed that kind of power.

I think using two PCIx on the same cable (without adapters) from the PSU should be fine. The manufacturer intended them both to be used on a high end GPU, so you should be fine.

molex has only 1 yellow (12V) line, and is generally only safe for 50-80W (rated at 60W usually). A pci-e 6-pin has 3 12V lines so it can handle a lot more power. Quality cables tend to be 16AWG or 18AWG and are needed if the antminer is going to draw 160-200W per port.

cheap chinese cables or molex-pci / atx-pci cables tend to be poor quality and often are 20AWG or even 22AWG (I has an atx-pci with 4->3 12V wires burst into flames in minutes. It was marked as 18AWG but during its autopsy the wiring looked like it was probably a 22AWG it was so thin) AVOID THESE

tldr; use one dedicated pci cable per antminer, and make sure its a good quality/brand
