It seems that they test and label their power supplies at 25 C, ...
Have you tested the high power performance at lower temps, or is this just speculation?

We wonder how this unit got the 80 Plus Bronze certification.
Perhaps the certification was given with the unit rated for 230V input only (increasing the efficiency)?

Speculation. Another cause could be that they send "golden samples" for the 80 Plus testing, a "tweaked" pre-production sample.

80 Plus tests are done at 115 V, not 230 V. Also pay attention how the manufacturer claims 89% efficiency on its website...

Normally yes, but not always. As per the test protocol, page 15, paragraph 4.2.1:
"The UUT shall be tested at one of the above voltage and frequency combinations that is closest to its nameplate input voltage and frequency."

If the tested unit isn't labelled for 115V but for 230V, then 230V is to be the test voltage.
