AMD Ryzen 7000 & Ryzen 7000X3D CPUs Show Very High Power Draw When Running Idle

wccftech.com:

AMD Ryzen 7000 & Ryzen 7000X3D CPUs seem to have very high power spikes even when running in idle mode, as discovered by Hardware Busters & Igor's Lab.

Although AMD has discovered the root cause of the burnout issues that are currently affecting several users and their Ryzen 7000 / Ryzen 7000X3D CPUs, some tech outlets started their own investigation and discovered something interesting. The testing done by Hardware Busters and Igor's Lab seems to show that at idle, the latest AM5 chips produce very high power spikes that might not be related to the burnout issue but something that could be addressed by AMD & its partners in future BIOS updates.

The testing was done using the Powenetics v2 system for testing which allows full measurements of power including transients. Transients have been a topic for a long time but the recent ATX 3.0 push made it come to the limelight as most PSU manufacturers showed how the newer standard has been designed to tackle these high transient specs that can be up to 4x the typical usage and power load.

For testing, a variety of AMD Ryzen 7000 & Ryzen 7000X3D CPUs were tested, & the most extreme case of these high transient spikes was seen on the Ryzen 9 7950X3D CPU. The CPU sipped an idle power draw of 130.04W (peak) which is above its nominal TDP of 120W and also far above its idle average which sits at around 50W.

The AMD Ryzen 9 7900X also saw an idle power consumption of 109.005W at the peak which is almost twice its average idle consumption of 63.798W. The Non-X Ryzen 9 7900 also saw a 95W idle peak whereas the average idle draw is around 48W.
