S7 Pros.  I have the following question

My 240V outlets won't be ready until next week but I have the S7 today with the 120V EVGA G2 1300W PSU with plenty of extra dual Ported PCI-E cables from other purchases. The EVGA G2 only have 6 VGA connections for PCI-E but with the Dual ports it will be more than sufficient to meet the 10 PCI-E requirement.  That being said, will it work with my EVGA G2 PSU running at 120V and what is the best way to connect it to unit?
