Yesterday I go Best Buy, but only good PSU in stock was Corsair CX750M 750W PSU. I buy this so I know I can definitely run 1 AntMiner at least and keep receipt in case I need returning it. 
I find out it bad idea to run 2 AntMiner blade on one PCI-E cable with other power supply. Cable cannot handle these loads and get hot like it going to melt so I turn it off fast. But I hear some people says CX750M can powers two AntMiner?
CX750M has two PCI-E cable with 2 plug ins each. But cables are very thick, unlike on other power supply. Maybe extra guage make them work?
Is possible to run both my AntMiner on CX750M? Right now I only runs one but wish I could run other till new PSU arrive.

Check out this thread, you can run two Ant's even over clocked off the DPS-800GBA

I've tried the CX750M to power two ants but It was _not_ reliable for me. I would frequently wake up in the morning to find that the PSU had over heated in the middle of the night and switched off and the problem seemed to occurred more frequently the longer I ran them. The cables do get a little warm but the real issue for me was the reliability two Ants is slightly above the rated capacity of those supplies I think.
Please buy RM 850 gold they're very stable!!! Cx750m cannot handle 2 oc ants!! Not even stock speed. You are endandering yourself be careful ! The psu and cable will get very warm be alert!
