Guus Hiddink's PSV are well off the pace set by Ajax, but they proved too good for RKC.
Jan vennegoor of Hesselink set the ball rolling with a strike on nine minutes, but they had to wait until after the interval before making the game safe.
Two goals in five minutes by Mateja Kezman and Park Ji-sung took the game beyond RKC.
As RKC chased the game, Kezman took advantage of the space to net his second of the match on 82.
AZ Alkmaar kept up their push for a European place with a 2-1 home win over struggling Vitesse Arnhem.
Martijn Meerdink and Robin Nelisse put the game beyond Vitesse with goals on 52 and 56 respectively.
The one crumb of comfort for Vitesse was the goalscoring return of Matthew Amoah who scored in his first competitive game of the year.
Mika Vayrynen's late goal handed high-flying Heerenveen a 1-0 win at Roda JC.
Basement boys Zwolle took a point from their trip to RBC Roosendaal, but they saw the side directly above them Volendam take all three points from their game at Twente.
Adil Ramzi fired Twente in front, but Volendam showed real spirit and goals by Maurice Buys and Dion Esajas completed a fine comeback.
