Does grounding a PC lead to less power usage ?

Hello,

Question:

Does grounding a PC lead to less power usage ?

(If it's not grounded than 120 volts placed on pc chasis so they say.)

Will this 120 volts placed on pc chasis lead to higher energy bills ?

They say the ampere/flow of electricity is low because of condensators or
something... but is this really the case ?

Do the power supplies perhaps have some switching electronics which will
make their work more efficiently when they
"detect" (?) grounding wire ?

Or is there no detection involved/no switching ciruits and is 120 volts plus
ampere simply send directly to ground wire ?!

To me this seems a bit strange but ok...

What would happen in a tower like "The World Trade Center" if it was stocked
with pc's everywhere... perhaps such a large building would have special
things... so how about a large appartment complex ?!?

Weird.

Bye,
Skybuck.

Hello,

When you touch the chassis and connect yourself to ground, there will
be some small heating effect in your body (and you will also
experience it as unpleasant). So see it just as a thought, not
something that you should actually do.

So theoretically spoken there can be some additional dissipation
because of Y-capacitor leakage through dissipating materials. However
when you look to the numbers, it will be negligible.

As that ground wire is essential for the safety of the equipment, the
equipment's plug should be plugged into a socket with safety ground
only.

A pure inductive/capacitive reactance across the line voltage does not
dissipate power by definition.

Of course the capacitive reactance will add some reactive current to
the line and hence cause some heat dissipation in copper series
resistance.

Since these filter capacitors are allowed to conduct only a few mA of
current (for safety reasons), the copper losses are nearly
unmeasurable compared to several amps load current in the same leads.
