Choosing the Right Power Supply
Why Recommend Headroom?
Modern graphics cards experience microsecond transient power spikes. Recommending a PSU with 20% safety headroom prevents sudden system shutdowns.
80 Plus Efficiency
PSUs convert AC wall power to DC power. 80 Plus ratings (Bronze, Gold, Platinum) represent conversion efficiency, reducing wasted energy, heat, and fan noise.
TDP vs. Power Draw
Thermal Design Power (TDP) represents a chip's heat output targets, not its absolute peak power draw. High loads like gaming can draw more than listed TDP.
