Sorry to say but these marks aren't enough to get any nit however you'll surely be able to other colleges which took admission through jee mains including IIITs but the chances of getting CSE are bit low but I think in further round of counseling you'll manage to get CSE so positively so for counseling.

Sorry, but I misunderstood your obc rank with general kindly ignore my previous answer.

Congratulations for scoring such a good rank in jee mains you'll get admission in any of the top NITS very easily that too with the core branches like CSE or ECE you just need to wait for counseling process to begin
Till then you can predict the colleges and streams you might be getting with the help of jee main college predictor and can also check the previous year's cutoffs of different nits .
