So that in the not so distant future less than 6 months I'll be adding a second gtx 780,classy to my build and in the next week be upgrading the rest of the computer.

I5 4670k
Corsair Vengeance 8gbs 1600
Motherboard GA-Z87X-HD3
Evga GTX 780 DUAL Classified ACX

I'm trying to find a good PSU that will power an additional classified in the future.

Will the corsair CX 750 M manage both and I don't mean watts I mean power off the 12v will be adequate if a classified requires 42a off the 12v and the PSU has multiple 12v rails less than 42a is it sufficient

Yea, a 750W should be able to power that just fine. The power requirements listed in product specs are typically based off the user having a low quality PSU and includes a worst case scenario CPU (say an overclocked AMD chip) in the figure. For instance I'm assuming from your mentioning of it that it says 42A on the product page? Thats 504W, far more than any GPU I know of can ever draw.

I would personally get a better PSU than a CX750, but in terms of pure wattage its more than enough.
