PSU Wattage Impact
Intel Core i5-13600K adds 217W to your system's transient peak (181W sustained × 1.20 transient factor).Intel Core i7-12700K adds 228W (190W × 1.20).
When pairing with a high-end GPU (RTX 5090: 902W transient peak), the CPU transient adds 217W or 228W respectively. Note: Intel Core i5-13600K can draw up to 181W sustained under all-core boost — ensure your motherboard VRM and PSU can support this. Note: Intel Core i7-12700K can draw up to 190W sustained — account for this in your PSU budget.
Frequently Asked Questions
How much power does Intel Core i5-13600K use at full load?
Intel Core i5-13600K draws 181W sustained (PL2 / all-core boost) and can spike to 217W during transient loads. Its base TDP is 125W. For PSU calculations, always use the sustained draw (181W), not the base TDP.
How much power does Intel Core i7-12700K use at full load?
Intel Core i7-12700K draws 190W sustained and peaks at 228W. Base TDP is 125W. Use 190W in your PSU sizing calculation.
Which CPU needs a bigger PSU?
Intel Core i7-12700K requires more PSU wattage with 190W sustained vs 181W. The difference of 9W sustained matters most when combined with a high-end GPU. Use PSUCheck's full PSU calculator to get the total system recommendation.
