PSG has now claimed the prestigious trophy on fourteen different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the match between the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired twice late to seize a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
