AMD TR2990WX Power Consumption and Best PSUs Recommendations

In our recent post, we discussed 2^nd gen AMD Threadripper processors. Today, we will go a little bit deeper into AMD TR2990WX power consumption matrices. We have a list of benchmarks describing power consumption of new Threadripper 2990WX on different applications and performance levels. It will help us to understand which PSU will be best for a rig powered by TR2990WX.

Before we jump to the list of best PSU recommendations for the new 2^nd Gen ThreadRipper 2990WX Processor, have a look at following table describing various facts and figures about power consumption of ThreadRipper 2990WX:

Table of Contents

ThreadRipper 2990WX Power Consumption:

As we discussed before, Both ThreadRipper 2990WX and ThreadRipper 2970WX has a TDP of 250 Watts. TDP stands for Thermal Design Power / Point. It indicated the maximum amount of heat generated by a processor chip. It barely affects the maximum power consumption but is positively related to it.

TDP	250 Watts
Power Consumption Idle	34.5 Watts
Power Consumption CAD(2D / 3D)	65.8 Watts
Power Consumption Gaming	86.1 Watts
Power Consumption Torture Loop	498.7 Watts
ThreadRipper 2990WX

Idle:

Now let’s talk about these figures. When a Windows 10 desktop powered by ThreadRipper 2990WX was kept idle for 30 minutes, the total power consumption by CPU was around 34.5 Watts. AMD’s efforts for minimizing idle power consumptions are pretty clear and impressive as TR 2990WX performed better than previous gen Treadripper processors.

CAD (2D / 3D):

The performance of this chip was not that impressive on CAD testing. Despite this test utilizing only four cores of the processor, the Threadripper 2990WX consumed almost 65.8 Watts of power. The TR 2950X performed much better in this aspect, which is pretty considerable as its performance level is pretty low compared to the TR 2990 WX.

Gaming:

When it comes to gaming, TR 2990WX beat most of the previous gen processors by both AMD and Intel. Playing Witcher 3 with 1080p resolution on GeForce GTX 1080 Ti (@ 2.1 GHz Water Cooled), overall CPU power consumption was 79.6 Watts. It is better than Threadripper 2950X, Core i9 7960X and many other older Intel and AMD chips. The benchmark implies that AMD’s second-gen Threadripper processors are way better in gaming compared to their predecessors. Even turning PBO didn’t leave any noticeable power consumption impact.

Torture Loop:

While trying to push the 2^nd gen AMD ThreadRipper processors on their edge, the TR 2990WX consumed about 498.7 Watts. It’s a worst possible scenario for any CPU chip, and mainstream users are very unlikely to confront it. However, we included these results to give you a better idea. Note that performance of TR 2990WX was worst compared to previous gen AMD ThreadRipper, Ryzen, and other Intel chips.

Best PSU Recommendation for TR 2990WX:

Considering that the chip requires an extreme cooling solution and other high-end components, the rig powered by a 2^nd Gen ThreadRipper 2990WX processor will require a stable, high efficient power supply which keeps the overall system nice and stable. Moreover, here we should also consider the possible memory and CPU overclocking. Thus, we recommend at least 800-1000 Watt PSU for an average build. Here are some recommendations:
