The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the net early on.
However, Marseille fired two times late to take a surprise 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 fortune, Goncalo Ramos snatched a vital equaliser in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen seasons.
