!forgive me if this is wrong place


Dear mates

I am having .5KVA UPS in that i have connected my 17" monitor and my CPU + printer

according to my ups vendor i have to get the power backup for 15 mins, but i will be getting oddly 4-5 mins, in between if i am switching off and switchon the monitor, thats up,

UPS will go down abruptly,

what i wanted to know is

how much power the pc consumes?

CRTs consume REALLY TOOOOO MUCH power. I too have a cerebra ups which is supposed to give backup of 25 mins on 14" col monitor, but for my 15" Samsung monitor, i get 15mins

I bet if it was an LCD, it would last for atleast an hour!!!

oops i forgot this:

U better not connect ur printer to ups especially if its laser.
The printer consumes a noticable amount of power (i think )

With out specific info like CPU, motherboard and type of stuff inside we can only guess. Backup time depends on the amp / hour rating of the battery and how much load.

A very rough guess which might be on the low side:
PC - 450 VA
Monitor - 172 VA
Printer - ?
Total - 622 VA

Your total load on the UPS is greater then its rating. If you want a longer backup time you will either need to reduce the load on the UPS or buy a bigger unit.

I would say that when you turn the monitor off / on you are creating a surge to the UPS which exceeds its capacity.
