A power supply is the most crucial element of building PCs that are often looked over. Having an inadequate power supply can result in catastrophic results such as damage to the motherboard, GPU, and even your CPU. So, it’s essential to choose an adequate power supply, especially if you’re aiming to play CPU-intensive games or run equally demanding productivity applications. Today, we’ll be looking at the best PSUs available on the market for the Intel Core i5 13600K.

The Core i5 13600K is a 14-core CPU, with 6 performance cores and 8 efficiency cores. On top of that, you get 20 threads with a CPU boost frequency of 5.10 GHz. While the i5 13600K is rated at a TDP of 125 Watts, power consumption can go beyond this threshold, reaching a max TDP of nearly 180 Watts. Therefore, you really need to get a beefy power supply to run this CPU paired with an adequately power-hungry GPU.

Intel Core i5 13600K power requirements

Despite Intel’s claimed TDP of 125W, the Intel Core i5 13600K can reach a max TDP of around 180W when running under full load at its boost frequency of 5.10 GHz. Based on these metrics, you’ll need a sufficiently beefy power supply. While you’d be fine with a PSU that outputs around 500W, it would be better to give the CPU and GPU a bit of headroom of 200–250 Watts.

This would not only give breathing room to the CPU and GPU but create tons of overclocking headroom if you plan to overclock the unlocked CPU. Considering the i5 13600K is an unlocked “K” variant CPU, you can tinker around with CPU frequencies to your heart’s content.
