Thats measuring the power INTO the power supply, not what its supplying
so isnt very useful for checking how close you are getting to the PSU rating.

Sure, but it certainly gives an upper limit for the output of the PSU.
So since my PSU never draws more than 180W on my Athlon 64 box, I know
that my 365W power supply is overdimensioned.

Of course one also has to take the load for the different voltages
into consideration, not just the overall rating, and the input wattage
does not help that much there.

PSU efficiency for typical loads seems to be around 70%-75% (give or
take a few percent depending on the quality of the PSU).

Its just a matter of time before all power supplies have some sort of load
monitoring method, just like most all motherboards now have software for
monitoring fan speeds, temperature, voltage from the PS. Has anybody seen a
smart power supply that can indicate load?

That would be a bad move on the part of the PSU manufacturers: It
would cost them money to include this feature, and it would convince
their customers to get smaller (cheaper) PSUs next time.


Followups set to colh, because I read that.

Right, and to hell with everyone else, who doesn't. Stupid troll.

In that particular situation you know that anyway from a calculation.

Which is what I originally said.

Utterly mangled all over again.

Wrong. Some would buy a supply like that.

convince their customers to get smaller (cheaper) PSUs next time.

You dont know that either.

**** that. You have always been, and always
will be, completely and utterly irrelevant.
