With my EVGA it just had a 24pin plug with the jumper wire attached. No extra mess. But since then I've made my raspi gekko Rig and using it via an ATX breakout board and voltage converter.
I have the same cable, but it's big and takes up space,
My OCD kicks in and I feel all that wire can be replace with a short jumper.
I'm also trying to find a wired or wireless relay controller to make this a switchable device, which I can do remotely, preferably from anywhere in the world
