The release of the highly anticipated Ryzen 9 7950X3D gives gamers an alternative to the almighty Intel i9-13900K when building the ultimate gaming PC. However, with a flagship processor like this, choosing the best power supply unit (PSU) is crucial. In this article, we’ll be discussing the best PSU for AMD Ryzen 9 7950X3D and what factors you should consider when selecting a PSU for your computer.
One of the advantages of the 7950X3D is its surprisingly low thermal design power (TDP) of only 120 watts, making it a highly power-efficient processor compared to other flagship processors. This allows users more options when selecting a PSU.
That being said, keep in mind that the GPU consumes most of the power in a computer, not the CPU. So, when selecting a PSU, it’s important to consider the TDP of the GPU you plan to pair with the 7950X3D.
Most users will likely choose an RTX 4090, which has a massive TDP of 450 watts, or another power-hungry GPU, so it’s essential to consider this factor when selecting a PSU.

What wattage does the AMD Ryzen 9 7950X3D CPU need?
As mentioned the AMD Ryzen 9 7950X3D boasts an impressively low TDP. The previous, non-X3D variant 7950, came with a 170W TDP, showing a high degree of power efficiency from the latest SKU.
The low TDP means you are going to be able to save a bit of money in the power department but it is still essential to ensure your GPU has adequate power.
Final word
It is important to have a good understanding of how much power your components will require. This will help you choose an appropriate power supply unit for your build.
To estimate your power requirements, you should consider the most common components you might use in your build, including the 7950X3D CPU, top-tier and mid-tier graphics cards, motherboard, optical drive, hard drives, and different-sized case and CPU fans.
By adding up the peak power usage of your components, you can get an estimate of the minimum wattage PSU you’ll need to power your build. We also recommend adding a buffer of 100-150 W to your estimate to allow for some flexibility and future upgrades.
It’s important to remember that if you intend to overclock your CPU or GPU, you should factor in the extra power needed. It’s recommended to choose a power supply unit with a slightly higher wattage than what you need to ensure that your system remains stable.
