    Looking for a little guidance for an assignment my teacher gave out. I'm not looking for a direct answer but some kind of input how I can figure this out. I'm pretty sure it has to do with what hardware I'm running but is there anything I need to know about the PSU to figure out the question below???

    "In this assignment, you have to select a power supply unit (PSU) for a
    desktop computer that consumes approximately 20 watts at idle time and
    60 watts at full load. The main criteria for selection is to minimize
    wastage of power. Provide a detail rational for your selection."

    The question seems like its missing some info...a PSU will run differently on different combinations of hardware correct? Shouldnt he be giving me the hardware that this PSU should be running on?

    The power consumption of a PSU will be the same regardless of the hardware configuration. What you need is a power supply that can handle at least 60 watts. The information of the idle power consumption is obsolete.
