PSU wiring question

post #1 of 5
Thread Starter 
I have a seasonic X-750 one of the 3.3v, one of the 5v and one of the ground wires is split into two at the motherboard connector. I am trying to sleeve it and because if the split wire the heatshrink makes it too big to fit.
I was wondering if it would be ok for me to clip one of the ends at the PSU side and just use a single wire at the motherboard connector? Im guessing this should be fine, but just wanted to ask to be sure before i toasted some of my gear. Or should i move the split and then sleeve that way?

Thanks guys

That's part of the voltage sense circuit. There should be a few other wires like that as well. Don't mess with them or you could affect the PSU's voltage regulation, or perhaps it might refuse to turn on.

Would it be ok to do this?

Thanks for the help Guru of All That Is PSU

I'm not sure. V-sense circuitry can be a little finnicky. With that setup it would be monitoring the voltage at the point it leaves the PSU, as opposed to where it reaches the motherboard. That would cause a difference in reading, thus a difference in output voltage, but it might not be a big enough difference to be an issue.

I'm not sure on this one, sorry.
