There is no assumptions. We did those calculations. And then designed the hardware. Temperature were cooler (as expected) because heat was also removed by chassis metal.
Meanwhile the point again. That computer that supposedly needs a 700 watt power supply is only rarely consuming 350 watts. We tell computer assemblers to buy a 700 watt PSU since they do not have (or have forgotten) basic electrical concepts even taught in high school physics.
If that computer was consuming anywhere near 700 watts, then it could also toast bread.
A 500 watt UPS is typically more than sufficient for a 700 watt PSU assembled by the typically computer assembler. Why so large? So that it can still provide 350 watts after three years.
