Case cables confused

Solution
Hmm you pictures didn't seem to come out. I think you need to have a couple more posts under your belt before you can post pictures. If you want you can PM them to me and I can take a look/post 'em here for you.

Edit: Ohhh I see what happened. nevermind your images work fine, I am just dumb :)

Anyhow, those are molex Y connectors. They are used for daisy chaining multiple devices off of a single molex coming from the PSU. Its safe to use them and it looks like you have them plugged in correctly. One of those ends should be plugged into the PSU.

So I should connect the male part to the PSU and just leave the female one alone?

 


If you have nothing else to plug the female part into, yes.
 

I took the cable from my psu labeled PERIF and connected it. Thank you all!
