Building a Mid-Range Gaming PC.
SSDs typically draw 2W–8W, while HDDs use 5W–10W.
The CPU is often the second or first largest power draw. Manufacturers provide a Thermal Design Power (TDP) rating (e.g., 65W, 105W). However, TDP is a metric for heat dissipation, not electrical consumption.
To estimate total wattage, one must analyze the consumption of individual components.
Multiply the total by 1.2 to 1.3 to create a 20–30% buffer. This accounts for transient power spikes and allows for future upgrades.
