Asia was touted as a supergroup in the 80s.
Apparently you weren’t paying attention. I heard them on the radio all the time.
If you mean groups that started/broke big in the 80’s and lasted quite a while, I think these qualify:
Metallica
Guns N’ Roses
Culture Club
Devo
Duran Duran
Tears For Fears
INXS
REM
