PSU wattage estimator
Choose your CPU and GPU, tweak drive and fan counts, and we'll tell you what PSU wattage actually fits. Sized to the PC-building-community convention of ~60% sustained load — so the PSU runs cool, efficient, and lasts.
Each NVMe / SATA SSD / HDD adds ~7 W under load.
120 mm fan ≈ 2–3 W. AIO pump adds another ~5 W.

We need both a CPU and GPU pick to estimate the total system draw.
