Ok, now I must admit I am a little confused, sorry.

When I look at my psu fan it is an intake fan by default, so did you alter your psus in any way, like take the fan out and turn it upside down so it acts as an exhaust, in which case the back perforated side of the psu would be taking air in?

Btw, my case is similar to your second case picture (Cooler master haf 922), for your first case picture with the dividing plate just above the psu it would obviously make no sense to mount the psu with the fan towards the inside.
