PSG has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions 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, Marseille fired two times late to seize a shock lead. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing shootout victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
