Choosing the best PSU for Intel Core i7-12700K

Finding the right PC components for a compatible build means considering the combined power requirement. The 12th Gen Intel Core i7-12700K has a TDP (thermal design power) rating of 125W base and 190W max, so creeping close to 200W on the CPU alone means taking a close look at your remaining hardware. Power supplies around the 650W mark are perfect for most modern builds, with the EVGA SuperNOVA P2 coming out on top in our best PSU for a gaming PC roundup and well suited here for the Core i7-12700K CPU.

Dropping any lower than 600W isn’t recommended unless you’re sticking to the onboard Intel UHD Graphics 770 GPU included with the i7-12700K, so the Thermaltake Smart is our choice for a budget PSU that’s easy enough to upgrade later. On the other hand, if you go all-out with a high-end graphics card and push the limits of PC gaming, you’ll need a premium PSU like the be quiet! Dark Power Pro 12, ready for 1200W of efficient power output. It’s the best PSU for Intel Core i7-12700K processors paired with high-end components.
