How much power does the Ryzen 9 7950X3D need?

The Ryzen 9 7950X3D needs a surprisingly low TDP of 120 watts, which basically means it consumes 120 watts of power under full load. That’s incredibly power-efficient, especially for a flagship processor. 

To give you some more perspective, the 7950X (non-3D) has a TDP of 170 watts, and the Intel i9-13900KS, the direct competitor to the 7950X3D, can consume as much as 320 watts of power under full load. 

The 7950X3D’s relatively low power consumption allows you some more options when choosing a PSU. But it’s important to understand that the bulk of a computer’s power usage belongs to the GPU, not the CPU. 

The 7950X3D is strong enough that you can easily pair it up with any GPU out there. Most users who opt for this processor will likely be looking to pair it up with an RTX 4090 to create the ultimate gaming rig. 

The 4090 has a massive TDP of 450 watts. This is something to consider when choosing a PSU.

Do I need a new power supply for the 7950X3D?

The 7950X3D itself doesn’t need much power. It really depends on the GPU you choose to pair it up with. If you pair it up with a low-power GPU such as the 130-watt RTX 3050, you could get away with using an older, weaker power supply. 

But the thing is, pairing up the 7950X3D with something as weak as an RTX 3050 would be a tremendous waste of resources. 

This ~$800 processor should really only be used in conjunction with the very strongest cards around today, such as the RTX 4090 and the RX 7900 XTX. Such cards have a TDP closer to 400 watts, so an older power supply likely won’t be sufficient. 

Ultimately, it comes down to the power rating of your PSU and whether or not it’s adequate for your build. 

There’s also the fact that older PSUs tend to not have the multiple 8-pin and 12-pin power connectors required by modern GPUs, so you would have to resort to using third-party adapters, which is extremely dangerous and highly inadvisable.

What goes into choosing a power supply?

• Wattage: Your PSU should have enough wattage to supply your PC build with its maximum theoretical power demands and then some. Having 20 to 30% headroom is recommended. 
• Efficiency: The more efficient a PSU, the less heat it produces, and the quieter it runs. You also save energy and pay lower electricity bills for your computer usage. Power supplies are rated according to their efficiency. 
• Modularity: Modular PSUs allow you to detach the power cables from the main brick. You can keep the ones you need and remove everything else to end up with less internal clutter. It’s best to have a modular or at least semi-modular PSU these days.

It’s perfect for a PC build with a 7950X3D. No matter what GPU you choose to go with in this build, the MPG A1000G will be sufficient. It comes equipped with the latest 12-pin power connectors. 

The PSU is 80+ Gold Certified. That’s not the best standard we have today (that would be 80+ Platinum), but it’s very respectable nonetheless. The actual efficiency of this power supply during operation varies from 87 to 90%, depending on the load.  

The MPG A1000G has a Zero Fan mode for quieter operation, and even when the fan is running, it doesn’t make a lot of noise. 

MSI is known for its reliability and offers you a 10-year warranty to guarantee long-term functionality.
