Update 2-3-2015

Installed a second PSU (750w) because the Corsair AX1200i was being short on watts and the system would restart. I have the 1200W powering two cards, hard drives and the motherboard and the 750W powering just two GPU cards. All fine till now. The Corsair Link is telling me that the system is just pulling 750W, so there is enough room to spare.  I will keep a lookout.

This is how it looks now.
