Power Consumption and Temperatures

For temperature measurement, I use a Reed SD-947 4 channel Data Logging Thermometer paired with four Omega Engineering SA1 Self Adhesive Thermocouple probes. One probe directly touches the chipset and two are placed on select power stages. The last probe actively logs the ambient temperature.


For the ASUS TUF Gaming X570-Pro (WiFi), one probe is centered along each bank of power stages. A probe is left out to log the ambient temperature. All temperatures are presented as Delta-T normalized to 20 °C, which is the measured temperature minus the ambient temperature plus 20 °C. The end result accounts for variation in ambient temperature, including changes over the course of a test, while presenting the data as if the ambient were a steady 20 °C for easy presentation. Additionally, there is no longer any direct airflow over the VRM with this new setup, placing extra strain on the VRM cooling.

For the numbers seen in the chart above, I am now using Prime95's Small FFT test for power consumption. For temperatures, I am using the maximum temperatures recorded over the course of my standard benchmark suite (this is almost always during either wPrime or Blender). However, relatively short tests do not put enough strain on the system to get a look at how the VRM performs at the limit, so I added an additional test to try to thermally abuse Vcore as much as possible.

This test typically involves a 30 minute Prime95 run at the maximum overclock the motherboard can maintain, again with no airflow over the VRM. For testing with my Ryzen 9 3900X sample, I chose 4.2 GHz at 1.35 V as the most intensive load I could manage in long tests without thermal throttling the CPU. Temperatures are logged every second, subtracting the ambient to calculate the Delta-T. The results are charted below.


The ASUS TUF Gaming X570-Pro (WiFi) did extremely well in my VRM torture test, with the hotter probe maxing out at around 65 °C. While the lack of a heatpipe between the two VRM heatsinks leads to a larger than normal delta between the two probes, both readings are easily within component tolerances.

There should be no doubt that this board can handle anything AMD has to offer.
