AMD Ryzen 7 1800X Review - Power Consumption

Power Consumption

In an IDLE state, a PC (motherboard / processor / GTX 1080 / memory / SSD) consumes roughly 50 Watts. This number depends 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. 

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, 3rd party 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 stress/load temperatures are very nice with temps at the ~70 C marker peaks (with a simple heat-pipe based Noctua U12S SE AM4 cooler). These, of course, are default results and not tweaked. The processor idles at roughly 45 to 50 Degrees C. Again, we used the AMD review kit supplied Noctua cooler here for cooling. We also received a liquid cooling kit (Predator 240 from EK) which we will use in the overclocking segment. That unit keeps the cores chilled at roughly 65 Degrees C under stress and being tweaked. Overall we are very happy with the temperature results here.
