Just a note, you will very rarely see the stress they put on the cross load, if using the PSU in a Pc, especially for gaming.
For mining, you may have a point on the +12v crossload tests, but isn't this a DC-DC unit?
Nah, it's a bog-standard double-forward group regulated unit, no DC-DC.

Pretty much the same other than the fan and connectors / housing. Same for M12II 620W.
The "crossload 1" test some reviewers do, with the heavy load on +3.3V and +5V and little on +12V, corresponds to conditions no computer will ever see. Maybe something from the 20th century without hard drives, possibly. It's kind of an academic exercise, not any real cause for concern if that goes wrong. A typical computer in the last several years and more may draw say 90% of its power from +12V. Some gaming builds might even peak at more; a fileserver with a bunch of drives when they're all spun up may have considerably less but nothing approaching even a 50-50 split, where TPU's crossload is like 15-85).
In other words, not really a concern. Cheaper power supplies tend to have group voltage regulation and have these issues under unrealistic test conditions (and a little worse performance overall under the realistic ones, though heavily depending on design and the load you use).
