Quick question about 6 pin pci-e cables

post #1 of 5
Thread Starter 
Are the wires interchangeable from harness to harness. For instance, I have a modular psu and my 6 pins have a harness on either end. On each harness pins 1-3 are are yellow wires and pins 4-6 are black wires. If I run a yellow wire from from pin 1, harness 1 to say pin 3, harness 2, would that hurt anything?

So my question is does the placement of the wires within the 3 pins (yellow on 1-3 and black on 4-6) have to match from harness to harness?

I know that's confusing, but I don't really know how to explain it any better.

I'm assuming it would matter, but try it at your risk.....

If the electricity flowing through each of those pins is different, it would matter. The one case I know it wouldn't matter is if you are just replacing one of the wires with a different one, and have harness 3 to pin 3 or whatever you're saying. As long as it is in the circuit it was intended for.

For those it doesn't really matter as long as the color coding is correct. The reason is that the contacts in the PSU originate and on the GFX card they are also all connected together; the reason the PCI-e power harness has 3 +12V lines is so that it can draw more current than it could over a single +12V line.

That's exactly what I assumed, but it's good to hear it from someone who knows. The reason I was curious is that I wanted to braid my individually sleeved cables. I wanted to know how careful I needed to be about labeling the wires in the pci harnesses.

Thanks for the input guys...
