Best Power Supplies For AMD Ryzen 7000

Ryzen 7000 power supply

The role of power supplies is often underestimated and while it is true that it doesn’t affect your PC’s performance, it does directly affect your components in many ways.

If you ignore the importance of a good power supply, then you may put your whole PC in danger. Therefore, we always recommend buying a solid and reliable power supply that can last for several years.

As the Ryzen 7000 series is out, things have changed somewhat when we consider the power requirements of these new processors. In this post, we will talk about how this will affect the power draw and what power supplies will be best for your PC.

Using Your Current Power Supply

If you already own a power supply from your previous or current build which has enough wattage capacity, you can simply skip buying a new power supply.

Most power supplies that have 4+4 EPS power connectors for powering a CPU will be sufficient for your Ryzen 7000 CPU needs. However, if your wattage is falling short, it’s time to buy a new one.

It’s still important to understand that if your power supply doesn’t have at least 4+4 pin EPS power connectors, you must buy a new one because the power requirement of Ryzen 7000 CPUs particularly the higher-end ones is much more than the previous Ryzen CPUs and many Z690 motherboards come with 4+8 pin power ports.

So, providing a sufficiently reliable and continuous voltage is essential especially if you plan to overclock which may succeed the stated TDP of these processors.

Power Requirements Of Ryzen 7000 CPUs

Since it’s important to consider the power consumption of your processor before buying a power supply, here is a chart of Ryzen 7000 CPUs with their default TDPs.

ProcessorsCores/ThreadsTDP
Ryzen 5 7600X6/12105W
Ryzen 7 7700X8/16105W
Ryzen 9 7900X12/24170W
Ryzen 9 7950X16/32170W

Note that these are the default TDPs as stated by AMD and the real-world power consumption will differ based on the load and clock speeds of these processors.

These CPUs easily exceed their TDPs even when they are not overclocked and when they are run at 100% load on their boost clock speeds. The 7900X and 7950X are particularly known to draw a power ranging from 170W-200W and 200W-250W respectively which are significantly higher than the stated TDPs.

This means you cannot just add the TDPs of all your system’s components and get a power supply based on that.

You should always add another 200W on top of the total max power consumption of your whole system if you don’t want your system to bottleneck.

For example, if the total max power consumption according to the default TDP of your PC components is 470W, get at least a 650W power supply to be on the safer side. You can always go higher which allows further smaller upgrades and even the continuation of the same PSU when you change your components.

Best Power Supplies For Ryzen 7600X and 7700X

Considering that you will use a CPU cooler, at least 2 storage drives, a few case fans, a GPU with around 150-300W of power consumption, and one or two additional accessories, you should add 250-400W by default to your power requirements.

Add another 120W on top of that for your CPU which includes the 7600X and the 7700X both of which have a TDP of 105W. So, we have a total max power consumption of your system somewhere between 370W-520W. This means we need at least 550W-650W of reliable power supply.

Best Power Supplies For Ryzen 7900X and 7950X

Assuming that you are going with a higher-end GPU with the 7900X or the 7950X, the power requirements will increase and as both these CPU consume considerably higher power than the 7600X and 7700X, we will need a higher wattage PSU.

If you are buying a GPU like RTX 3080 or 3090, we recommend going with the 850W PSU listed below or if you are considering a more power hungry GPU like the RTX 3090 Ti or 4090, consider the 1000W PSU.
