My concern is who works in a room where the temp is 45C plus? I understand the PSU can get that warm internally (is that what they are talking about essenially?), but the intake air is still 23C or so, right?
Is there anything wrong of using a lower temperature to test power supplies? No. It is just our personal preference to test power supplies at real-world temperatures.
The “problem” is that during our reviews we’ve seen several power supplies that received a certain 80 Plus certification but at a higher temperature they don’t achieve the same efficiency level. For example, some power supplies labeled as “80 Plus Silver” would need to be labeled as “80 Plus Bronze” if they tested the unit at a higher temperature range.
the air in your case doesnt stay at 25c forever now does it?
Is the ambient temp the same as the operating temp of a PSU?
I'm sure a PSU with an appreciable amount of load will be hitting 45°C internaly.
Maybe I wasnt being clear or I am misunderstanding this. Like a CPU the ambient temp is not the same as its operating temp, unlike a CPU there are numerous components to a PSU that do not operate at the same temp. How do you tell what the actual operating temp is then?

There is no one single operating temp for a PSU. Best you can do is monitor the exhaust temp.
The ambient temp rating on a PSU is for the temperature of the environment the unit is installed into. If it's 50, that means the OEM has carefully designed it so the internal components don't fry when the incoming air is 50 degrees.

I'b be about ready to pass out with 50 C incoming ambient while I was reaching for a cold Sam Adams.
