Now with the new Ryzen 7000 non-X series, there is a focus on better power consumption and much lower temperatures. The Ryzen 7000 series runs hot, and they can consume a lot of power and so it can be a bit of a turn-off.
So now with the non-X SKU, we get a lower TDP and power consumption. This will make it easier to run and won’t require as much of a cooling solution. Which makes it a bit more efficient to run in your system.

Although if you’re wondering about the wattage of the system then you need to find out how much each component will consume. And even though the CPU has some impact it’s not as great as a graphics card.
What is the Ryzen 7 7700 TDP?
With the drop of the X, there has been a drop of 40W as well. This means you get a lower power usage along with a lower temperature of the chip. Dropping that much from the 7700X means the new TDP is only 65W.
So there is a much lower impact on the overall power of the system. And it gives you more power to put into the graphics card. With a bit less power needed from the PSU.
Do I need a new PSU for Ryzen 7 7700?
Now if you’re looking to feature the non-X CPU in your build you may be looking for a new system. But just because you are buying a new CPU doesn’t mean you need another power supply if you already have one it could do the job.
So if your old PSU has enough wattage for the new build then it should be enough. As long as it is also working well, and is from a trusted brand that can still deliver good power years on. Also as long as it also has all the features you need like the right power connectors.
