Well I don't know, do the math and calculate your power needs. You need to take into account that this is not an easy case to use two separate psu (I'm not gonna test my welding skills against price of 4x7990 rig What I can tell you is that I'm going to build 3x 7990 next week with one psu G1600 air cooling in open case like lian li ti60 or i will make my own open case. If you want you can wait I will sure post my experience.
