Find the TDP (Thermal Design Power) or "Graphics Card Power" for your CPU and GPU. Go to PCPartPicker

Adding a 30% buffer ($615 \times 1.3 \approx 800W$). Result: An 850W PSU would be perfect for this system, allowing for spikes and slight overclocking. Find the TDP (Thermal Design Power) or "Graphics

Once you have your total estimated wattage,

125–250W (especially when overclocked) 3. Motherboard and RAM These are relatively low-draw but still count. Motherboard: 40–80W RAM: Approx. 3W per stick of DDR4/DDR5. 4. Storage and Cooling SSD/HDD: 3–10W each. Fans/RGB Strips: 2–5W each. Liquid Cooling (AIO): 15–30W for the pump and fans. Step 2: Use a PC Wattage Calculator
