will that psu be enough?

my kill-a-watt confirms the accuracy of this calculator to an error of only 7 watts. use it and size your own psu

This calculator gets my system wrong by about 215w (about 30% off), adjusting load accordingly. Unfortunately, this has been typical for the several online PSU calculators I've used across many builds. Same for the recommendations from various component manufacturers—they all tend to overestimate by a significant margin.

you included your overclock and used a good tool to actually test your system at full load? sorry to hear that was so far off.

the one i linked says i need 514W at full load with my exact system specs and overclock in addition to 10% capacitor aging (my psu is 2 years old). i verfied with my kill-a-watt, which shows i'm running around 520W while running OCCT's psu stress tester. that's pretty damn accurate of a guess from an online calculator.
