PC Power Draw Estimator
From component load figures, estimate what your PC actually pulls from the wall.
Estimate idle and load power draw from your CPU, GPU, and the rest of the system. Use this to size your PSU and estimate running costs.

Idle includes light browsing/desktop; load is a heavy render or benchmark. Size the PSU ~30% above peak load (700 W) for efficiency and headroom. See the PSU Wattage Calculator for a full parts list.
Idle vs load
Idle draw covers light desktop use and browsing; load draw is a render, benchmark, or heavy game. Annual energy blends the two using your daily load hours. Size the PSU roughly 30% above peak load for efficiency and headroom. For a full parts list, use the PSU Wattage Calculator.
