Generally people recommend large amounts of headroom when putting together a new build in case you want to upgrade in the future. Not that you should buy a new PSU every time you change graphics card. Buying a new one just for the sake of it for an existing build when the one you have works just fine makes zero sense. Equally, at the time I bought my current PSU back in 2014, 750W was always the wattage that people suggested as being more than enough for any single-card system, with anything higher being "overkill". I guess people didn't imagine a future where GPU power consumption continued to rise despite companies shaving 20nm off the manufacturing process since then. I remember how much people freaked out about the power consumption of the R9 290X at the time, yet now we have cards that can easily pull 150W more than one of those and it's "normal" now and you should have definetly bought a 1000W PSU bare minimum.

Doesn't bother me anyway, as I always undervolt my cards. Already have a 900mV profile done that seems stable for my 3080, which performs slightly better than stock because it no longer crashes against the power limit constantly.
Most quality PSU’s will do more than their sticker rating by at least 10% and then shut down without spiking power into any other components. The Superflower Leadex III 650W Gold I bought went over 700W before shutting down in tests. The 750W version went to 833W.
With you there bro
Yeah but why would you risk using over-design limits? Everything is heading the wrong way - temps, efficiency, longevity nooh!
It's also coped with other high power draw cards like the Radeon VII on silent mode for years too, really solid units.If I was building a whole new PC knowing I would have a 3080 of course I’d buy a higher wattage.What GPU do you have? In 99% of games I play, my 3080 is at between 300-350W in GPUZ. Basically, whenever your playing a modern game at a high resolution, a 650W PSU or some 750w's will be close to 90%, depending what CPU/other components you have.
Not a wise decision, though let the ignorant face the consequences I say
