The Ryzen 9 7950X is AMD’s answer to Intel’s Raptor Lake lineup, and it performs exceptionally well across the board–both as a gaming CPU as well in CPU-intensive applications across the board. When you’re done marrying it to the right motherboard and GPU, you might want to take a minute to think about the PSU unit you’d hook it up to. If you think a 500-watt PSU would do the trick–owing to current-gen CPU efficiency, you would be wrong.

While AMD claims that the Ryzen 9 7950X has a total power draw of just 170 watts, that’s far from the truth. If you check out the Package Power Tracking on a Ryzen 9 7950X, you’ll find that the total power draw tops off at around 230 watts under max load and at a boost frequency of 5.7 GHz.

What PSU Do I Need For The Ryzen 9 7950X?

Despite AMD’s claims of a total power draw of just 170 watts. The Ryzen 9 7950X tops off at around 230 watts, which is just 60 watts shy of the actual rating. But there are lots of factors to account for when choosing a suitable PSU. Surely, you’d marry your beastly processor to an equally exceptional motherboard and a beefy GPU. 

Then you would have to account for GPU and CPU overclocking headroom if that’s your cup of tea. And finally, you’d have to look at the number of peripheral components attached to your PC including; case fans, RGB lighting, NVMe, SSDs, and optical drives. If you’re going balls to the walls, then we’d recommend a 1000-watt power supply, but if you’re just doing some CPU-intensive stuff and don’t mind using low-budget components, then you’d be fine with a 650-watt PSU.
