The Parisian club has now claimed the season-opening cup on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 champions and the French Cup winners after the French winger opened the net early on.
Yet, the southern French side struck two times late to take a shock lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
