The Parisian club has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the French league winners and the French Cup winners after Ousmane Dembele found the net early on.
However, the southern French side fired twice in the closing moments to take a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
The record winners PSG, who met 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 thirteen years.
