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?

The 1300G2 will work fine with an S7, but you have to manage the current flow in the PCIe connectors. The 1300G2 has 6 PCIe connectors. Use 5x single PCIe cables, and 1x double PCIe cable. Connect 2 cables to each blade of the S7 (the S7 does not need all 3 blade connectors to be populated; it runs fine with just 2 connectors per blade). One output of the double connector goes into an S7 blade; the other output goes into the S7 controller. This works because the controller requires very little power. So you end up with 6 cables from the 1300G2 going into 7 S7 connectors.

Each of the 3 S7 blades uses about 400 watts (~1200W total for an S7). Splitting that between 2 PCIe cables means 200W per cable. This is well within spec for the 16-gauge wires that the 1300G2 comes with. Note that each S7 blade has 3 PCIe connectors, but only 2 are required.

this WILL void warranty as per BMT. if possible i would connect all 3 pcie to each hashboard.
