Still think 1000W PSUs are overkill for gaming builds

Three years ago I built my rig with a 750W unit and regretted it after adding a 3080 and overclocking my i7 last month. Power spikes kept tripping the OCP during Warzone drops and I finally swapped to a 1000W Corsair last week. Anyone else find that their high-end parts need way more headroom than the calculators suggest?

Yeah that "1000W is overkill" thing is exactly like how people say you only need a certain size fridge for a family of four. Then you get the thing home and realize the freezer can't hold a single Costco run and you're wedging leftovers in like Tetris. I ran a 750W on a 3080 with a mild overclock and got shutdowns just loading into Modern Warfare lobbies. Swapped to 1000W and it's like buying the bigger fridge - you don't use all of it every day but man is it nice not having to plan around the limits.

The transient spike thing is the REAL issue nobody talks about when they say 750W is fine. Even the best 750W units can trip OCP when a 3080 pulls 450W for just a millisecond during a loading screen. I had to underclock my Core i9 just to keep my old Seasonic from freaking out. The calculators don't factor in those microspikes and its a total nightmare when your PC hard crashes mid raid.
