Hey guys I'm wondering about how my Seasonic 750 handles PCIe power over the supplied cables.
I'm sure other PSUs are like this as well: I'm running my 290x on a single line from the PSU - the line on the GPU-end is split to offer two eight-pin connectors (which can be split again for 2x 6-pin connectors). No problems so far, but I got to thinking about how these were wired up...
I assume Seasonic supplied the proper wire gauge to handle both connectors but the thing that concerns me is the way the 2nd connector is split from the first. The second connector's wires basically nest into the first connector. If that doesn't make sense, here is a picture: Link - imgur.com
I am no electrician, but I can imagine running all the current through one connector like that might not be the best idea. I haven't been having any problems, but due to paranoia I will go ahead and install a second power lead. Initially I thought that less cable mess would be nice, but now I'm thinking this might not be a good idea if I want to exceed 300w on the GPU. Is this something to be concerned about or is this a non-issue? I know my PSU is a single rail, so the power is all coming from the same source - its just this split connector I'm worried about.
