PayPal Unauthorized Transaction

January 30th or 31st I sold this gpu on ebay to paige , it was delivered to provided address on February 3rd.
Today is now may 3rd and I receive an email saying he preformed a chargeback as "unauthorized transaction" .
Is paypal going to fuck me? The tracking number shows it was delivered . So that's the proof I have. I think I might have transactions from my bank from when I purchased the shipping.
Will paypal favor him in this case, will I really have to pay the 107 back ? Anyways to avoid it?
