I loaded the PSU at 110% of its max-rated capacity at 42C, and it didn’t break! This is something to write about! The 230VAC input helped here, so this unit is only rated at 200-240VAC. Moreover, the group regulation scheme brings problems in the CL1 and CL2 tests, where I apply a high load on the 5V rail. During the CL4 test, the 12V rail also drops low, but it doesn’t cross the 11.4V limit.
Load regulation is loose on all rails, with 5V achieving the best performance, with a 2.66% deviation.

Ripple is high, as expected, at 12V during the full load test but is at reasonable levels at lower loads. The unit only fails at 5VSB, at the 110% load test, where I pushed the PSU beyond its capabilities.

In the pro and cons section you mention that it has both high build quality and low build quality. which one is it?
I left an error on purpose to see who would notice 😀
Bad build quality
