Yes, unless it's a thin computer cable or unless you jump into the noose from a height. If you don't drop into the noose from a height, AND it's a thick computer cable, it should work. Make sure what you're suspending from is also strong enough. If you jump from any height, you could easily be applying a force of 2-5x your weight or even more depending on how flexible the support is etc which could snap even a thick cable with your sudden deceleration
