Yes, it comes under the TNAU counselling.

May I know what's your rank?

The admission process of PSG College of Technology is based on Tamil Nadu Engineering Admission (TNEA) conducted by Anna University Chennai. Further, TNEA is a counselling process, which is based on 12th marks. Hence your JEE percentile does not matter here. If you have good marks in 12th then apply for TNEA counselling process under other state quota by using TNEA website:
