[SOLVED] Why is my power button led flickering?

[Nomion108]

Recently, I built a new pc (specs at the end) and once I booted it up I noticed that the led on the power button on top of the case (NZXT H510) was flickering. I went back and made sure the front panel connector was fully plugged in, but it kept flickering. Just wondering if this is a problem I should be worried about or it its normal.
