When even the bloody high-end 80 PLUS Gold Fortron Aurum haven't turned off while having 10,79 V at +12 V, I somewhat came to the conclusion the bloody cheap Weltrend secondary monitors are PoS. If you are interested, I can translate the review later. My editor in chief will come back from IFA soon and take a look at the Huntkey FX500SEs visit rate so we'll decide if it's worth publishing at Diit.
Now they even state mostly in the very datasheet they have so wide range of input that they are more or less useless if you ask me. I mean the voltage tolerance but obviously the current tolerace is same shit. Maybe they are good for the scenario you load the PSU with 150 % it's power instantly, but that's all.
I don't want to read through all that reviews of mine but from all the PSUs I reviewed so far which did have this IC, maybe one or two have actually shut down (if any, don't really remember). The rest either blew up or I just stopped it before it happened because it was pretty much sure where it leads. I also count in the 8pin versions which do not monitor current but should at least shut it down when voltage goes too low.
Part of the problem may also be the fact manufacturers use Pi coils as shunts more and more. I asked about this phenomenon here before with no conclusive answers but I haven´t seen many true shunts lately. I think their resistance DOES vary with flowing current and that they are generally very inaccurate.

Half of the computer problems is caused by bad contacts
