Power consumption

Such total measurement is possible only if the PSU supports power consumption monitoring. Otherwise you get partial values for some components/rails only.
Many thanks for quick reply, Martin and greetings from Heinsberg, the most western town of Germany.
Have a nice weekend.
Alternatively a good/accurate power meter or energy meter can be used, you know, the ones you plug between the wall outlet and the PC (or any other device one wants to measure). In German they're called "Energiemessgerät" or "Energiekostenmessgerät".
