When you’re getting one of the better mid-range options from Team Red’s 7000 series lineup, the Ryzen 7 7700X, the last thing you want to do is skimp out on the PSU. The power supply is responsible for delivering power and bringing your PC to life. If you go for a shoddy power supply, then you might just end up with fluctuating power delivery and, in the worst-case scenario, damaged components.

The Ryzen 7 7700X steps in with 8 cores and 16 threads. AMD claims a TDP of 105 watts for the CPU. As for clock speeds, it features a base frequency of 4.5GHz while boosting to 5.4 GHz under max load. If you check the PPT time limit for the Ryzen 7 7700X, then you’d be surprised to know that it draws a total of 140 watts under load, which is 35 watts more than the stated TDP.

What Power Supply Do I Need For The Ryzen 7 7700X?

Thankfully, the actual power draw of the 7700X is not far off from AMD’s claims of a max TDP of 105 watts. But you do need to factor in power overhead for overclocking, which could very well raise the TDP beyond this limit. Pair it with a beefy GPU and tuned clock speeds, and you could definitely look at sturdier PSU options.

If you go for a top-of-the-line graphics card, you raise the total power draw to around 900 watts. But if you’re going for a more budget-friendly mid-range build, you can opt to tone things down. Paired with a mid-tier GPU, the total power draw can range anywhere from 400 to 550 watts. Add some breathing room, and you’d see yourself buying a 600-watt PSU.
