The CX750's have 4 PCIe connectors but they are doubled up on only 2 sets of wiring so if you plan to max out the power draw realistically you should be careful not to burn your wires. A couple pages back there is a photo from someone who burned up the wires on their CX600 which has two connectors on one set of wires.
You're slightly wrong, cyper didn't burn up his cx600m. He was using an extender cable on his cpu power cable and the extender burned up. I'm currently using the same cx600m that has a single pcie with split ends. At default clocks, the psu is holding up well. The wire gets extremely warm but not hot. I don't understand how people read one thing and get it all switched around and post something different. It's like that gossip game kids play where you whisper something in someone's ear and pass it down. So much wrong info by the end of it.
Yes and the Ebay seller who sold me the extension cables refunded me today.
The CX600M have more than enough power for even the highest possible overclocked Ant. Just make sure you cut and strip the CPU cables and use these for one of the boards.
Also the max Amp per 12V cable for 24/7 use according to CoolerMaster is:
The official standard only allows for 75W on a 6-Pin PCI cable. I don’t know why this value is so low (it’s not a free specification for some reason). More info here:
http://www.playtool.com/pages/psuconnectors/connectors.html#eps8I found several different information as to the max Amp on one cable (7A for 18 AWG seems most common) so 252W per cable.
Unofficially it would be ok but it’s at your own risk! Just make sure you have plenty of airflow running over those cables.
I don’t know why there are only three cables included. We can send you another cable. Please send us your full address.

And the max safe temp is:
Apologies for the late reply.
That is correct, all cables are rated 80 degrees Celsius for testing. You can withstand temparature up to 80 degrees Celsius with any issues.

Notes:
Stock power consumption is approx 360w and approx 400w-ish for OC power consumption.
Someone feel free to correct me if I'm wrong.
P.S. a Corsair CX-500 will work just fine with 1 ant miner (42A on the 12v line; same as the CX-600).
I measured 320W stock.
Also CX500 has only 34A on the 12V line, so might not be enough for overclock.
