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. 

Above, in blue the Ryzen 3 1200 and in black the 1300X under various load conditions - there is a dedicated graphics card installed (GTX 1080)

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.
  

 
We use the cheapest AMD compatible heatpipe cooler for this review. With the Noctua cooler we see the Ryzen 3 1200 (shown above) with a max temp UNDER 40 Degrees C. That is running a 1024M Prime test.
 

 
The Ryzen 3 1300X runs max 50 Degrees C, which is still very little considering we use heat-pipe cooling and are running 1024Mb of Prime calculations.
