PSG has now secured the season-opening cup on 14 separate times.
The Parisian giants required a stoppage-time 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 European champions appeared to be sailing towards a straightforward win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele opened the net early on.
However, the southern French side fired two times late to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 seasons.
