Someone please correct me if I am wrong, but I believe just the Jupiter alone will need 4 PCI-E connectors. I believer each of the PCB takes one PCI-E connectors, so for both of your orders, you will need 6 PCI-E Connectors. Seems you might be needing to get that extra PSU.
Ok, a clarification on the thermaltake psu. It's got EIGHT 8-pin pci-e power connectors on four cables, which is what I meant by four connectors. Each cable splits into a pair of 6+2 pci-e power connectors. It will definitely power two miners.
Which leads back to my original question: Should I run two miners on one psu? Is it safer to run a separate psu for each unit? I do have a spare 650W corsair psu, which I could use for my Saturn and save the Thermaltake for the Jupiter. This may not be as efficient at the wall, but it could prevent both miners from crashing if a single psu fails. How often does that really happen with a 1475W thermaltake gold psu, though? The geek in me says I should use the single PSU for both units. Not just for efficiency of electricity, it means having less power cords to deal with and less space taken up by external psu's.
