No, it isn't. We just always see it being used by a very evil guy.
From the script of Ocarina of Time:
The Triforce...the sacred triangle...it is a balance that weighs the three forces: Power, Wisdom and Courage. If the heart of the one who holds the sacred triangle has all three forces in balance, that one will gain the True Force to govern all. But, if that one's heart is not in balance, the Triforce will separate into three parts: Power, Wisdom and Courage.
Only one part will remain for the one who touched the Triforce... the part representing the force that one most believes in. If that one seeks the True Force, that one must acquire the two lost parts. 674
Those two parts will be held within others chosen by destiny, who will bear the Triforce mark on the backs of their hands.
<PERSON> touches the Triforce in an attempt to use its wish-granting powers, but his heart is not in balance. He ends up with the Triforce of Power, while the other two pieces ultimately grant themselves to <PERSON> and <PERSON>.
Seven years ago, <PERSON>, the King of Thieves, used the door you opened in the Temple of Time and entered the Sacred Realm. But when he laid his hands on the Triforce, the legend came true.
Although I don't think the specifics are discussed, it's clear from the games that having one piece of the Triforce does grant some manner of special powers. <PERSON> seems to be more or less immortal even in his human form. However, there is no indication that the Triforce piece has granted him evil powers; rather, he is evil, and uses the Triforce to do evil things.
From <PERSON>'s answer:
The Triforce grants wishes to those who touch it. Since the Triforce does not distinguish between good or evil, it allows both good and bad wishes.

It stands to reason the same goes for the powers of the individual Triforce pieces.
I don't believe the depiction of <PERSON> turning evil you reference is canon or based on canon details.
The games have never shown us anyone besides <PERSON> being granted the Triforce of Power, so we don't know when or how else it's been used. Based on the way the pieces of the Triforce grant themselves to humans, you could say the Power fragment is the most likely one to go to an evil person, though. 674
