which is really more of an RGB fiber optic overlay held on by strategically placed cable combs to look like 24 lit wires going to your motherboard's 24-pin header.
I'm a little confused on how this works? The sentence above seems to explain it but it sort of goes over my head.
The actual light-generating LEDs are likely located at the end of the cable, and the light travels along the optic fibres to cover the length of the cable.
If you look at the 2nd picture, you can sort of see the comb. The point being made is that it isn't the actual wires coming from the PSU that are being lit up. It's just an array of 12 fibre optic wires, each of which are held directly over the 12 pairs of wires that are in a 24 pin cables. Each pair of wires along with one of the fibre optics fit between teeth in the comb, holding the fibre optics in place and in line over the PSU wires.
Idk if that makes it any clearer lol.
