| I plan to hook only the PC and the monitor. How much should I plan for future? How power future computers will need? (Less/More) |

|  If you don't have a printer or any other dvice, which shares power from UPS, 500VA is enough. But if there is, you need a 600 or better 800VA UPS. Choose the one that gives good out put voltage with less fluctuations for a long time. |

| Depends on how long you want the PC to run with the power off. 350VA will buy you about 5 minutes (with monitor, no printer), where 500VA will give you a little short of 10. Obviously larger VA ratings will give you longer run times. Most of the run times I'm accustomed to are based upon CRT monitors. LCD's will likely give you more time since they draw less current than CRT's. BTW: DON'T attempt to run a laser printer off a UPS...the laster draws too much amperage for the UPS to handle and will likely trigger the UPS alarm as soon as it's turned on. An inkjet will not have this problem, but, unless you're in the professional print business, don't connect your printer to it. |
