Seasonic M12D 850W Rail Configuration

post #1 of 4
Thread Starter 
I recently bought the Seasonic M12D 850W, but this PSU is a dual rail design and there is no label or manual telling me which output is connected to which rail. I tried to search on review and there is no indication which connector isl inked to which rail. Can someone let me know which PCI-E is connected to the first rail and which PCI-E is connected to second rail? Thanks in advance!

It still only has one 12V power source, so don't worry about it too much. There aren't really two rails, just two copper traces (monitored individually, with OCPs calibrated at 40A each) coming from the same +12V source.
But if you're curious, Jonnyguru's review of that unit appears to have that information if you scroll to near the bottom of the first page:

At the bottom of the review it says the one of the hardwired PCI-E is on 12v2 and other on 12v1. Any idea which cable is it?

There's nothing more I can tell you. You'd have to open up the PSU to know for sure, assuming the PCB is properly marked.
But like I've mentioned, I think you're worrying about it too much. I'd just hook everything up and move on.
