Quick question does it matter which way I plug my cables in?

[spat55]

Just had a thought and I don't think I've ever researched this but does it matter which way the ATX/PCI/EPS leads go into the motherboard? I'm 99% sure it doesn't but maybe the alcohol has screwed with me too much

It should not be physically possible to connect them in the wrong orientation. So the question isn't "does it matter", it's "is it possible".

On my boards, that's an 8-pin plug wire, and there's only one 8-pin plug for it on a motherboard.

Or maybe I misread what you mean by "ATX/PCI/EPS." That power-plug wire is usually designated as "ATX/EATX." At least, as I recall . . .

Yes, it does matter.

If you look at them they are keyed to only go in one way. Look at the ends and you will see squared off terminal housing tips and round ones. I thought everybody knew this.

As did I, or I might have explained it myself.

I was just interested as I've always put my connectors on with how they have the clip to hold them onto, when I took my PC apart for dusting I had a proper look at all the cables, I hadn't really thought about it in my time building.

Now you know.
