[SOLVED] What is a power SW and a power LED and what do they do?

[blocklerpath]

I am building a gaming PC for the first time, but there are some things I am confused about. There is a power SW cord, and a power LED cord. What is the difference between them, what do they allow to work, and do I really need them? Thanks

The power SW allows you to power the computer using the power button on the PC case.
I think you might need that one.
The power LED shows a LED light on the computer case when the power is turn on.
The power LED might change colors or blink depending of the state of your system (power on = solid / sleep = blinking)
