Default Contact resistance in ATX power connectors causing grief

Just a thought, I imagine each embedded motherboard has several other

lot of people seem to think it is, shouldn't all the connectors be failing?

Probably right Lance, but maybe a bit of extra resistance does not
matter so critically in all circuits. Also the discussion has not
mentioned the necessity for good mechanical pressure in the
connectors. I had extensive problems with otherwise good connectors
in another set up where the spring fingers were not having or
retaining their intended springiness.
Also the contact material may not be as good or pure as hoped for.
