If you are here wondering why your custom cables caused your RGB effects to be dimmer here are some answers.
   Drop Alt and Ctrl are possibly the most power demanding keyboards out there. 
The keyboard itself contains each individual key RGB lighting + More under-glows.
 The reason that it comes with such ashort cable out the box, is because with longer cables, power is lost in transfer due to the distance it has to travel. That's why your DROP keyboard may look dim with a Kustom Keys cable, as the coil makes the cable much longer,

How Can I fix this?

- Get a powered USB hub (USB hub + Power Outlet)
- Configure your motherboard's BIOS to deliver more power to the desired USB port
