It should be noted that the LED lighting is active ex works even when switched off. On the one hand, this can be annoying, but it also results in unnecessarily high power consumption. The board consumes a full 4.5W when switched off. By deactivating the LEDs, the power consumption can be reduced to 2.5 W when switched off (depending on USB devices and standby). A certain amount of power consumption can never be completely avoided when a PC is switched off. The power supply unit supplies power to the motherboard via the 5VSB line even when switched off, e.g. to enable connected components to be charged via USB or the PC to be switched on via LAN.
How high the power costs of the PC are with or without overclocking depending on the performance and running time can be calculated with our interactive PC power cost calculator:
