I am not familiar with computer hardware, and I am trying to change my graphics card. I currently have a GT 610, but I am trading it out for a GTX 1050 Ti
GT on the left, GTX on the right:

I am trying to get the GTX to fit, and I am certain it will fit (just barely). The problem is, there are some wires in the way that, if I can move them, I can get the graphics card in, and then easily move the wires around/over/under the card. I was able to move all the other wires, but I am not sure what this one wire is, and I do not want to try to remove it until I do know what it is, and how to remove it.

The Wire (2):

What is this wire, and how do I remove it? I would seriously appreciate the help, I just spent $229 dollars on this card, and I don’t want it to go to waste.
