It's a Corsair CX600M. Is anybody else using those with the AntMiner? How are you connecting the PCIE cables?
I just bought the same power supply (Corsair CX600) for the AntMiner S1.
It looks like there's only 1 PCI-E wire with two 6-pin connections.
You must be confusing something! The CX has two 500 mm cables, each with a 8-pin (6+2) PCI-E connector. (

Is it safe to use that 1 cable and connect to 2 boards of an AntMiner?
If the PSU had only two 6-pin connectors, it would be probably not powerful enough at all, as they were only designed to provide 2x 75W max.
On the other hand - even if there were two 8-pin connectors on one single cable, I would not expect problems in environments with normal ambient temperatures, because the manufacturer had to design it to provide 2x 150W, which nearly matches the overall power requirement of an antminer.
Overclocked, it will be around 30% over specs and will heat up the cables+connectors - an aspect which must be taken care of in any case (single or dual cables).
