According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

The heat will be too much of a problem unless you water cool.  They will not last. 
Seller since 2011 hundreds of orders shipped

i have added all possible coolers and maybe will only work 3 of them at every machine..

but for now i need to know if it works out with the power consumption on the 1200watt PSU ?

Do note, You will still need a radiator/pump and reservoir for those water cooled cards. All they come with is a waterblock preinstalled.
