No, you cannot multiply the rails like that. If you check the label (picture available on Newegg), you'll see that there is 680W availalbe for the 3.3V, 5V, and 12V rails combined. Thus, no more than 680/12 = 56.67A is available on the 12V rails, under the (rediculous) condition that there is no load on the 3.3V and 5V rails.

Moreover, the GameXStream is identical to the FSP Epsilon 700W (yes, the one in my rig), and the FSP website states that the max load on the 12V rails is 50A.

With multiple rail PSUs, you rarely see that the total max load on the 12V rails is the same of the individual rails added up. The limit of the individual rails is exactly that: the max load on that one single rail.

PS: 72 x 12 = 864W.... bit high for a 700W PSU...
