Power Consumption

Power Consumption

In an IDLE state, a PC (Z97 / Pentium G3258 / 2 x 4 GB memory / GeForce GTX 780 Ti / SSD) consumes roughly 40 to 50 Watts, remove the graphics card and run it from an IGP and that value will even lower itself. Bear 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.

Now more interesting is to remove the graphics card and to see how it behaves then. As shown in the chart above only the embedded IGP is used, the power consumption is great. In IDLE we measured 40~50 Watts and, with processor load, 77 Watts for the entire PC. That is very low.

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 this is an indication. Next to that, we stress all CPU cores 100% and thus show a PEAK power consumption. Unless you transcode video with the right software your overall/average power consumption will be much lower.

Overall very nice temperatures, we are using Corsair H110 LCS cooling setup.
