I wonder if my system is good or bad. My server needs 0.1kWh.

    You might have your units confused.

    0.1kWh over how much time? Per day? Per hour? Per week?

    Watthours refer to total power used to do something, from a starting point to an ending point. It makes no sense to say that a device needs a certain amount of Wh, unless you’re talking about something like charging a battery to full.

    Power being used by a device, (like a computer) is just watts.

    Think of the difference between speed and distance. Watts is how fast power is being used, watt-hours is how much has been used, or will be used.

    If you have a 500 watt PC, for example, it uses 500Wh, per hour. Or 12kWh in a day.
