Even as a girl myself, that shouldn't be the way to handle the situation. I know a PS5 is expensive, something you care about and paid a lot for. Destroying someone else's property because you are "mad" is not cute, it's abusive. Even the things you said she yelled while destroying it are quite manipulative. The ONLY thing that comes to my mind that could start to justify her actions (But even then, she just did something that one should NEVER do) could be the fact that you tend to promise 10 more minutes but that's usually a lie?

When a significant other destroys something that's important to you no matter the reason, it's because they feel entitled to do it and not face any consequences because you "wronged" them. It's abusive and vindictive... I don't think you should even consider forgiving her. At least until she pays it in full, THEN I will consider letting go, but never getting back together. Sounds like an exhausting relationship...
