If you are from general category and somewhere near 60 you will easily get admission in some of the top colleges for masters but regarding PSUs, it is difficult to ascertain whether you will get the call or not.

IITB,IISC will close at approx AIR100.
IITD,IITM, approx AIR 150 to AIR200
IITK Separate Written Test,Interview(Shortlist Cutoff AIR400-500)
IITKGP,IITR approx AIR 150 - AIR 300
IITH,
IITJ,IITP, Approx AIR 200 - AIR 350 - AIR 500 - AIR 600

NITT,NITK,NITW etc Approx AIR400 - AIR1000
NITC,NITA etc Approx AIR 800- AIR 1200
DCE,NSIT,COEP etc Approx < AIR 1400,1500

SO overall i can say that if your score is above 65 nobodies can deny the calling from psus for interview round.
