And I need your help with installing the PSU.
Which is the correct PSU orientation --the psu fan facing up or down, and why?

You should try with the fan facing down. You could do with fan facing up but the airflow in that case towards the PSU would be stifled by the PSU basement baffles.

You mean if I have PSU with fan facing up would be stifled by the PSU basement baffles. Right?

Not with your be quiet! case. There's a lot of space between the PSU and tho top of the PSU shroud, but you have to lower the front casefan a bit that it blows air under the shroud.

What do you mean? Can you explain again please?

Mounting the PSU with the fan facing up is possible but there must be some airflow under the PSU shroud. You can create that by lower the front casefan that blows air under the PSU shroud.

Okay. Do you know, if I find a example?

 

[--SID--]

Example of what?

My advise: mount the PSU with the fan down because that's what the grill and filter on the case floor are made for.

 

[elegendx]

Okay.
In which PC Case would the power supply be with the fan facing upwards?
Can you see me a PC case?

Barely any case and in reality none.

99% of decent cases now have bottom mount psu slots with an external grill and filter.


These cases are designed to face the psu fan down and isolate the psu entirely from the rest of the system airflow and temperature wise.

Really the only time a psu fan should be pointing into the case if it's an old style topmount slot in which case you have no choice.
