The power doesn’t change, but you get 12 systems that each need to dissipate 600Wh instead of a single system that needs to dissipate 7200Wh. You can for example partially buffer the heat if you know that you only need to handle that load for a few minutes. It’s much harder to sustain the same energy dissipation for an hour.
