Power Supply Wattage 'link' Now

Efficiency is the ratio of DC output power to AC input power. Losses are dissipated as heat.

| Component | Typical Power Draw (Watts) | |-----------|----------------------------| | Low-end CPU (e.g., Intel i3) | 35–65 | | Mid-range CPU (Ryzen 5 / i5) | 65–125 | | High-end CPU (Ryzen 9 / i9) | 125–250+ | | Low-end GPU (GTX 1650) | 75 | | Mid-range GPU (RTX 4070) | 200–250 | | High-end GPU (RTX 4090) | 450–600 | | Motherboard + RAM | 30–70 | | Storage (SSD/HDD) | 5–10 per drive | | Fans & USB devices | 10–30 total | power supply wattage
