The Parisian club has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele found the net early on.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
