PSG has now won the season-opening trophy on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck twice late to take a surprise advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen years.
