The French champion has not lost in its last 26 league games since a 1-0 reverse away to Reims on March 2, with its previous best of 27 being set in 1994 on its way to a second Ligue 1 title.
Having won the title under Carlo Ancelotti last term, PSG has pushed on under Laurent Blanc and is top of Ligue 1, although Lille closed to within a point on Tuesday with a last-gasp 1-0 win over Olympique de Marseille and a staggering 11th consecutive clean sheet.
The consistency of Lille and the attacking prowess of Monaco - which beat Nice 3-0 on Tuesday despite the absence of Radamel Falcao - means les Parisiens face a fight to defend their title, but their crushing 4-0 win over Olympique Lyonnais on Sunday showed they remain the side to beat this season.
Zlatan Ibrahimovic scored twice from the penalty spot, adding to efforts from Edinson Cavani and Thiago Silva.
In the way of the milestone sits an Evian team without a win in three games and sitting 16th in the table.
Pascal Dupraz's side went down to a 2-0 defeat at Bastia on Sunday, leaving the coach lamenting some sub-standard defending.
The suspended Fabrice Ehret is unavailable for Dupraz, while the game may come too soon for striker Kevin Berigaud (thigh).
PSG may also have to reshuffle for the clash with Thiago Motta having been withdrawn at half-time in the Lyon win, putting his involvement in doubt
