Question: how much power supply for overclocking?
Answer: So, now our power requirements look like this: 200W for CPU/motherboard, plus 250W for GPU, plus 75W for other components, plus 100W for overclocking. This totals up to 625W. We recommend that you select a PSU that will meet your system's target power requirements when running at 50 to 80% of its rated wattage.
