depends how lone you want them to stay up - not long if they are only server connected....
APC has a chart showing how long the Battery will provide power based on standard 200W draw

the basic unit start @ 400VA if i remember correctly and provide like 5 min - enough for a short power hiccup
we use at least a 500VA which is good for about 10 minutes
or sometimes the 650 if we can get it cheap usually they are like $75
there are definitely bigger and better

If you are using remote desktop then the server is really the only thing that needs to have a UPS. All the lifting and data is help on the server and the connection will be kept alive.. seems like a strange thing to power proof these single workstations..

Do you get frequent power interruptions for 1 - 2 mins or something and its causing time issues..? otherwise I think this is an expenditure that is possibly pointless.

To keep alive at a minimum you need


And depending on how many switches/servers you use this may be quite high..
can you explain your setup a little more and what you are hoping to gain from power proofing these machines..?

all good comments...

so let me be a bit more specific .

my units are all PS clones which i built from components.  i am looking to protect them for about 10 minutes.... until power  brown out is restored, and absolutely from power surges.   all have a 400   - 600 power supply.  All have  1 or two hard drive and the MB. and a non-gaming video card or on board video.
what is my power need.

they are rated in measures   650 Va /390 W       i just do not understand how to convert this to my needs..

perhaps this is a clearer picture as to what i am looking to do.

any help appreciated.

i see units are rate

styles like this    APC Back-UPS BE550G     can they by standing upright, or must they be flat on the floor.  much less of a foot print on its side..?
don't use the power rating - measure what power you need for the pc, + screen, and whatevere devices you like to stay up
