Cost to install 15A GPO?

Afternoon guys,

I have purchased a used 1600W UPS that requires 15A GPO. I currently
only have standard 10A GPO's where the unit will be going.

As it stands now, all the gear that will be run off the UPS runs fine
off the one 10A GPO - three computers, no monitors and a bit of
networking gear. A very rough, completely over exaggerated estimation
they would draw 1400W.

The outlet is only 6M from the breaker board and is on the same circuit
as a home theatre system (large CRT TV, audio amp, Digital STB...etc),
microwave and other miscellaneous devices.

Two questions:

1/ I'm of the opinion that I shouldn't just run the UPS on the 10A GPO.
Is this technically correct? Given that the devices run fine now is it
one of those 'will probably work but don't do it' situations?

find out how much current the device uses to charge it's battery add that to
your total peak equipment load.

2/ If I have to install [wait, wait...if I have to pay a qualified
electrician to install] a new 15A GPO what is a rough guestimation of
cost?

That depends on where the cable is run and how hard it is to access those
places. cheapest is probably to cut a hole in the wall and pur in a pull
string the sparky can use to pull the wire through, (may involve drilling
studs, removing roofing material and other fiddly bits. but does give a good
finish)most expensive is getting the electrician to do the same but he
hopefully knows how,
in between is running the cable in a conduit where it can't easily be routed
under the floor or above the ceiling.

It also depends on how busy the building industry is this month...

I'd be most suprised if it can't be done for under $500 prolly muchh less.
but I'm guessing.


Bye.
Jasen

3 average PCs and the network gear might draw 300W tops on average,
probably less IMO. Maybe peaking
higher during disk activity, startup etc.
You don't know much about PC's then! A Pentium CPU by itself
requires
about
100W each. Have you ever wondered why a single PC power supply is
rated
at
300-500 Watts, or more? Maybe your "average" is for a 24 hour period
where
the computers are turned off 2/3rds of the time?


I suspect you are suffering under a misapprehension as to the actual
consumption and power rating of a power supply , perhaps you might
investigate OHM'S law .
I'm well aware of ohms law. You OTOH have no idea about modern PC
power
requirements when they are actually working.
Or maybe you are claiming to have a PC power supply with greater than
100%
efficiency??

Once again I say you sir really know sfa about the inner workings of a
computer , google surge and Ohms law .


What exactly should I be looking for? If Intel says a Pentium draws 135W
at
full load, (Ok the new ones are only 95W) how do I power it from a 100W
power supply? Where does the power come from for the rest of the
computer?
What is the efficiency of the PSU?
Please provide all the Ohms law calculations you believe are
appropriate.

Do you own work sport , it will be far more worthwhile.

In other words you have no idea what you are talking about. If you used
Google yourself, you could find out just how uninformed you actually are.

however keep in mind the power supply is work case max , it takes more
to spin a drive up than to keep it spinning .(generalized example and
have fun)

And hard drives are the least of your problems unless you have a few. Even
some video cards draw more than 100 Watt these days. The heatsinks and fans
aren't just for show!
But you may still be running an 8086 with CGA and floppy disk drive I guess
