An estimate, not a spec sheet. It uses typical tier wattages, not your exact parts, and adds ~40% headroom so the supply runs cool, quiet and efficient (and leaves room for an upgrade). Check your GPU maker's own recommended PSU too — a spike-prone card can want more. Nothing you pick leaves the page.
