Strange PCI-E cable configuration.

    Decided to teach myself how to sleeve properly rather than the hashy rubbish I have done in the past, with that in mind I bought some lengths of sleeving from OCUK got a set of tools and started on one of my spare PCI-E cable and noted that it has what I think is a capacitor connecting a black and yellow wire. (See image 1 and 2) yet the one of the cables I had made by Pexon do not have this. (Image 3)

    I am confused, what purpose does this serve and if it is important why have the custom made cables have similar?
    PSU is a Silverstone Strider plus 500w.

    Having a look through my box of cables I noted that the PCI-E cable that has the capacitor has a blue 8 Pin Female PCIe GPU Power Connector on one end with a 6 pin connector the other and is 600mm long. The shorter version 400mm long has a black 8 pin connector at one end a a black 6+2. The shorter cable does not have the capacitor.
