iBuyPower at CES 2018: RGB LED Lighting... on Power Cables
 

There's almost nothing left inside a PC that could be fitted with RGB LEDs. At least that was our assumption until we came across iBuyPower's suite at CES this year. For the person that has RGB everything, how about some RGB cables to go with it?

Technucally iBP isn't adding LEDs to cables themselves here - they are lit up through a cable management piece which connects to the cables as opposed to the cables themselves. The RGB LED cables to provide their light through cable management attachments which mount to individual cables shining their light down and around the cable path. iBuyPower wanted to integrate the lighting right into the cables themselves, however, after testing they found it was not practical as the wires were too rigid among other findings. Users are able to daisy chain up to three of these devices which connect to an RGB header on your motherboard allowing you to light up the full length of most cable runs.
