PSG has now claimed the season-opening trophy on fourteen separate times.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times late to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a vital leveler in the dying moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a convincing shootout win.
The record champions Paris Saint-Germain, who met 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 seasons.
