The Parisian club has now secured the prestigious cup on 14 separate times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to get past 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 featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired twice late to seize a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
