What power supply?

Aren't most modern high end PSUs going to have a 0db mode while they operate under a certain temperature?

Yeah, but not a wattage-based thing, it's a heat-based thing. If you hotbox the unit at a 50W load then the fan will still make jet engine noises.

Aren't higher wattage PSUs going to be more efficient at lower loads?

If it's 0db until 30% load doesn't the 1000W unit have a higher floor for 0db mode vs a 450W unit?

That's entirely bullshit, if your PSU intake is 25c then it's *technically* correct, but on a higher end system that won't be the case. 0DB modes also increase component stress. A good PSU without 0DB mode is better as it can remain silent (enough that you won't hear it over anything else) whilst maxing component reliability.

Aren't most PSU components like motherboard mosfets/caps only going to have major issues above 90C?

Yes and no, most parts are fine well above 100c, but their lifespan increases exponentially below their rated temp - a rule of thumb (at least for caps) is double the lifetime for a 10c reduction.
