Beck's conjecture on coloring of graphs associated to various algebraicobjects has generated considerable interest in the community of discretemathematics and combinatorics since its inception in the year 1988. The versionof this conjecture for power-graphs of finite groups has been addressed andpartially settled by previous authors. In this paper we answer it in theaffirmative in complete generality, and, in effect, we establish a "nicer"statement on a larger class of graphs. We also clear up certain ambiguitiespresent in the way the previous versions of the conjecture were posed.
