Did not register with me that that was a laptop.
As such power would be via an adapter or a battery. Appears to be 180W or perhaps 230W

That said, does the following link match your laptop?

I immediately noted under CONS: " Keyboard doesn't support RGB backlighting"
And you are plugging the k68 rgb keyboard into one of the laptop's USB ports - correct?
Not sure that that is at all workable as I understand the circumstances and specs.
