Power Consumption

Power Consumption

In an IDLE state, a PC (Z170 / processor / 2x4 GB memory / GeForce GTX 780 Ti / SSD) consumes just under 65 Watts, remove the graphics card and run it from the IGP and that value will even lower itself to just under 50 Watts. This number depends on and will vary per motherboard (added ICs / controllers / wifi / bluetooth) and PSU (efficiency). Keep in mind that we measure the ENTIRE PC, not just the processor's power consumption. Your average PC can differ from our numbers if you add optical drives, HDDs, soundcards etc.





Based on just an IGP, thus no dedicated graphics card installed, we idle at 50 Watts and max out at roughly 115 Watts (no graphics card has been installed in that condition).


The above measurement is without a graphics card, thus IGP only. I want to make it very clear that power consumption measurements will differ per PC and setup. Your attached components use power but your motherboard can also have additional ICs installed like an audio controller, LUCID chips, network controllers, extra SATA controllers, extra USB controllers, and so on. These parts all consume power, so these results are a subjective indication. Next to that, we stress all CPU cores 100% and thus show peak power consumption. Unless you transcode video with the right software your average power consumption will be much lower.


Overall excellent temperatures, we are using a Corsair H110 LCS cooling setup.
