We ask the question whether supernovae created by young and massive stars within Nuclear Star Clusters (NSCs) can feed Supermassive Black Holes (SMBHs) at the centers of galaxies. We use numerical simulations showing that supernovae occurring near the galaxy rotational axis or inside Circum Nuclear Disk (CND) supply to the vicinity of the central accretion disk surrounding the SMBH the supernova ejecta combined with the mass collected from the interstellar medium by the expnading supernova expanding shells. The mass deposited by individual supernovae varies between 1 and a few 100 solar masses depending on the position of the supernova and on the density of the ambient medium. Supernovae occurring in the aftermath of a starburst event can deposit 10^3 - 10^6 Msun into the vicinity of the accretion disk within 30 Myrs. The fate of that mass is split between the growth of the SMBH and outflow from the nuclear accretion disk.
