I did not say a damned thing about current limiting.

It is surge sensing. If your PC is up with its 1000W supply only
using 250W of it, and you try to add a hard drive while it is live, you
can cause the entire supply to shut down, even though the HD and all of
its inrush only taxed the rail a few more watts. It can also happen
merely adding a CD or DVD reader as well. It is the change it senses,
even if well below its max capacity.

Hot swap supplies do not do this function. ATX supplies do. That is
why they are so hard to use as a bench supply.

but if a laptop
is on the edge of the maximum current from a PSU, then it could shut
down intermittently or have other problems, the cause of which may not
be clear to the user.


Hardly a difference one would experience in your example of a mere 0.5
amp differential. Now try to move the goal posts again.


You're clearly after an argument. I'm just suggesting the way that a
standard for laptop power connectors could be implemented, bringing
up largely irrelevant points isn't going to get anywhere whether
they're right or not.

Probably China, but ASUS should have some control over the design
and manufacture.

No. The chinese ps makers have their own engineers and are the best
at it after decades of doing it (literally), and ASUS picks one from
their lines and has several M of them made, and they only thing they get
that is custom is the labeling and a guarantee that they will not kill
(read stop producing) the model.


Then that's the control ASUS have over the design and manufacture of
their power supplies. Cheap ones from Ebay do not have the assurance
of that approval by the laptop manufacturer.

Knock-offs bought directly from China may not have
been adiquately designed for the application,

Nobody said anything about buying a false branded "knock-off".

There are literally hundreds of ps makers who make good products and
they do not need a brand sticker to guarantee tagged performance. That
is what CE and TUV and UL certs are for. And YES, they ARE valid cert
declarations.

Sheesh.


Some of the laptop power supplies on Ebay are fake OEM products, I
should have said "third party" instead of knock-off, but I meant ones
that are not OEM branded. Either way, there is little assurance that
the design is sound and truely approved. There are plenty of poor
charger designs, some with fake certifications, shown in teardowns
on the web.


No need for any tear down. Place the output on a scope and put the
supply under its full rated load and look at the ripple. It really is
that simple.

Come back an hour later and check the case temperature and ripple
again.

Easy greasy chin-o-****in-nesey.


That covers safety for equipment before the components age. It doesn't
reveal safety for people with regards to things like circuit board track
spacing that are covered by safety certifications.

The average consumer also has to brave the electronic frontier without
the aid of an Oscilloscope or variable load.

Defecant_Linux_Luser_Numero_Uno is a very angry person with some serious
mental issues. He needs to make an appointment with a good shrink.
It seems to be common in the Linux community for some odd reason.

Anyway, here is a tear down of a cheap iPad adapter vs the real thing.
It has nothing to do with being made in China and everything to do with
being made to manufacturer's specifications vs something that is made as
cheaply as possible and barely works.

**** you, you retarded jackoff.

Somebody should take a nice, splintery NYPD broomstick handle and
shove it up your ass till it comes out your mouth.

It appears that trip would only be a couple inches, however.

Disappointing Decadumper, not even 3 inches.

Is there a more recent article like the following...

for the US market?
